Description

When your Ford truck build demands a TKX with the shifter in the straight-up OE position, this MDL exclusive modification delivers exactly that. Standard TREMEC TKX shifter locations work great for many applications, but some builds -- particularly trucks with floor-mounted shifters or specific console clearances -- need the stub positioned differently. MDL solves this problem through careful machining and component integration that brings the shifter stub straight up with no offset, all while maintaining the TKX's legendary durability and shift quality.

The front mount tall body configuration provides additional shifter height, making this transmission ideal for truck installations where the standard shifter housing sits too low. MDL's engineering team hand-prepares each transmission, ensuring precise shifter positioning and flawless operation before it ships. This level of customization simply isn't available from TREMEC's standard catalog.

Built on TREMEC's proven TKX platform, this transmission delivers 600 lb-ft of torque capacity with engine speeds capable of 8,000 RPM and shifts at 7,500 RPM. The close-ratio gear set features a strong 2.87:1 first gear for confident launches and a deep 0.68:1 overdrive that drops highway RPM for relaxed cruising and improved fuel economy. Multi-cone synchronizers with hybrid carbon/bronze rings deliver superior shift quality at high RPM, while the ribbed 3-piece aluminum housing provides outstanding structural stiffness with reduced NVH. Tapered roller bearings on input, output, and countershafts combined with caged needle bearings on the mainshaft ensure long-term durability.

This Ford-pattern TKX requires a Ford Wide Pattern bellhousing and 26-spline clutch disc. The 0.670-inch pilot tip fits standard Ford applications. Both mechanical (7-tooth cable drive) and electronic (OSS two-wire analog sensor) speedometer outputs are included. Fill with 2.7 quarts of Dexron-III ATF, TREMEC HP-MTF, or Mobil 1 Synthetic ATF.

Description

When track time demands maximum shifter precision and your Ford build needs the most aggressive shift position possible, this MDL-modified TKX delivers road race-ready performance in an exclusive configuration you cannot buy from TREMEC. The tall body shifter mounts in the furthest forward position on the case with zero offset on the shift stub, placing the shift lever exactly where a road racer needs it during hard cornering and aggressive downshifts.

The TKX platform represents TREMEC's ground-up redesign of the five-speed manual for the aftermarket. Its end-loading three-piece aluminum case reduces overall height and width compared to the TKO it replaces, eliminating tunnel modifications in many classic applications while increasing structural rigidity. The close-ratio gear set opens with a 2.87 first gear to keep the engine in its powerband through technical sections, while the 0.68 overdrive delivers highway cruising capability for track day drives. Multi-cone synchronizers with sintered carbon/bronze hybrid rings and double-lined carbon-fiber facings enable clean, positive shifts at 7,500 RPM - a major improvement over older five-speeds.

TREMEC engineered the TKX with special gate chamfers and ball detents on all three shift rails for improved shift quality with reduced notchiness. All gears and shafts are manufactured from ASTM 4615 special-grade steel with oversized gear widths for maximum durability. Tapered roller bearings on the input, output, and countershafts reduce noise while caged needle bearings support all gear positions. The internal three-rail shift system with steel shift forks keeps all linkage lubricated and protected.

This Ford-pattern TKX bolts directly to Toploader-style bellhousings and shares crossmember mounting points with TKO transmissions for straightforward swaps. The 31-spline output shaft accepts Ford C6-style slip yokes with 1310, 1330, or 1350 U-joints. Both mechanical and electronic speedometer outputs are built in. Short input shaft kits are available separately for applications using original four-speed bellhousings.

Description

When your truck build demands factory shifter positioning, standard TKX configurations fall short. MDL's modified TREMEC TKX solves the tall body shifter challenge with precision machining and custom component integration that brings the shifter stub up to the OE truck position. This isn't a bolt-on shifter - it's a completely reworked transmission with the tall body shifter housing integrated as part of the unit. Every modified TKX is hand-prepared at MDL's Caldwell, Idaho facility to ensure quality and precision.

The TREMEC TKX represents the next generation in 5-speed design with its compact end-loading architecture. This layout delivers greater tunnel clearance, increased case strength from the ribbed three-piece aluminum housing, and fewer case seams with gaskets at all mating surfaces to eliminate fluid leaks. The slim profile fits most transmission tunnels without floor modifications while the robust internal design handles serious power.

Shifting performance comes from multi-cone synchronizers and sintered carbon/bronze hybrid synchronizer rings with a non-leading tooth profile - enabling smooth, positive engagement even at 7,500 RPM. Tapered roller bearings on the input, output, and countershafts reduce noise and improve performance, while a caged needle bearing supports the mainshaft. The single-piece countershaft and oversized gear widths increase torque-carrying capacity across all gears.

The Ford Wide Pattern bellhousing interface provides broad compatibility with Ford applications. Both mechanical (7-tooth cable drive) and electronic (OSS two-wire analog) speedometer outputs are built in, along with a reverse light switch on the left side and cruise control safety switch on the right.

Description

Eliminate bellhousing flex and the accelerated drivetrain wear that comes with it. The QuickTime RM-6060 steel bellhousing connects Ford small block engines (289, 302, 351C, 351W) to Ford T5 Mustang, TKO 500/600, TKX, or TR3550 transmissions using standard-length input shafts. Unlike cheaper alternatives made from rolled or stamped steel, QuickTime's unique spin-forming process creates a cone that maintains perfect engine-to-transmission alignment throughout the entire RPM range.

The engineering advantage is measurable: high-grade steel that work-hardens to over 80,000 PSI delivers more than twice the strength of competing steel bellhousings while keeping weight down to approximately 20 pounds. This rigidity translates directly to reduced input shaft wear, consistent clutch engagement, and improved power transfer. The bellhousing is 6.925 inches deep with a universal transmission bore of 4.850/4.910 inches, designed for use with 157-tooth flywheels and clutches up to 10.5 inches.

This is a universal-fit bellhousing -- not vehicle-specific -- making it ideal for engine swaps, restomod builds, and custom applications where the factory bellhousing won't work. Universal shifter fork brackets accommodate mechanical, cable, or hydraulic clutch linkages. Note that transmission mounting bolts are not included. QuickTime holds patents on 16 points of bellhousing design and process, with input from OEM engineers, engine builders, transmission builders, and racers. Made in the USA.

Important: This bellhousing is NOT SFI certified. Many sanctioning bodies require SFI 6.1 certification for cars running 11.49 or faster in the quarter mile. If you need SFI certification, see QuickTime RM-6065.

Description

When you're running deep into the 11s or faster, track officials aren't going to let you stage without an SFI-certified bellhousing. The QuickTime RM-6065 delivers that certification while solving another critical problem: bellhousing flex. Lesser bellhousings made from rolled or stamped steel distort under load, causing accelerated wear on your input shaft, pilot bearing, and clutch assembly. QuickTime's patented spin-forming process creates a bellhousing that maintains perfect engine-to-transmission alignment throughout the entire RPM range.

The difference is in the manufacturing. QuickTime cones are spun rather than rolled or stamped, resulting in the most dimensionally stable bellhousing on the market. This high-grade steel construction work hardens to over 80,000 PSI - more than twice the strength of conventional steel bellhousings - while keeping weight down to just 22 pounds. The compact design provides clearance for headers without requiring tunnel modifications.

The RM-6065 connects 6-bolt small block Ford engines (289, 302, 351W, 351C) to Ford-pattern T5 (standard-length input shaft), TR3550, TKO 500/600, or TKX transmissions. The universal 4.850/4.910-inch transmission bore accommodates all these gearboxes, while the 157-tooth flywheel compatibility and 10.5-inch maximum clutch diameter handle serious power. Universal fork brackets work with diaphragm or cable-operated linkage, and the bellhousing accepts cable, hydraulic, or mechanical clutch release systems.

This is a universal fit bellhousing - not vehicle specific - making it ideal for swaps, restorations, and custom builds where you need proven SFI 6.1 protection without compromise. Proudly made in the USA with patents on 16 points of bellhousing design and process.

Key Features

• Complete transmission-to-bellhousing fastener set sized specifically for aluminum bellhousing applications
• Engineered for TREMEC TKX installations on Ford Small Block engines (289, 302, 351W)
• Bolt lengths optimized for aluminum bellhousing thread engagement - not compatible with steel bellhousing kits
• High-grade steel construction with hardened washers for reliable clamping force
• Eliminates hardware guesswork when upgrading from factory T5 or other transmissions

Description

Factory T5 transmission-to-bellhousing bolts are incompatible with TREMEC TKX transmissions, and aluminum bellhousings demand different fastener lengths than their steel counterparts. This hardware kit eliminates the guesswork by providing the correct transmission-to-bellhousing fasteners specifically sized for TKX-to-aluminum bellhousing installations on Ford Small Block applications.

Aluminum bellhousings have different thread depth characteristics than cast iron or steel units, which means using the wrong bolt length risks either insufficient thread engagement or bottoming out before achieving proper clamp load. This kit contains bolts cut to the precise length required for aluminum bellhousing applications, ensuring full thread engagement without interference.

Built from high-grade steel with hardened washers included, these fasteners deliver the clamping force needed to keep your transmission securely mounted under hard acceleration and aggressive shifting. Whether you're building a Foxbody Mustang, classic small block-powered Ford, or any other vehicle running a TKX behind a 289, 302, or 351W, this kit ensures you have the right hardware for a proper installation.

Note: This "AL" kit is specifically for aluminum bellhousing applications. Bellhousing bolt lengths differ between aluminum and steel bellhousings - some bellhousing manufacturers include their own bellhousing-to-block bolts, so this kit focuses on the transmission-to-bellhousing fasteners you need to complete the job.

What's Included

• High-grade steel transmission-to-bellhousing bolts (lengths optimized for aluminum bellhousing)
• Hardened steel washers

Key Features

• Bolt lengths sized specifically for steel bellhousing applications - not interchangeable with aluminum bellhousing hardware

Description

When upgrading to a TREMEC TKX 5-speed transmission, factory T5 transmission-to-bellhousing bolts are incompatible with TKX applications. This hardware kit provides the correct bolt lengths and grade specifically engineered for steel bellhousing installations on Ford applications. Steel bellhousings require different bolt lengths than aluminum bellhousing kits - using the wrong hardware can result in improper engagement, case damage, or unsafe mounting conditions.

This MDL hardware kit solves the sourcing headache by providing the exact fasteners needed for your steel bellhousing installation. The Grade 8 bolts deliver the clamping force necessary to handle the TKX's 600 lb-ft torque capacity, while hardened washers ensure even load distribution across the bellhousing mounting flange. Proper hardware is critical - never use transmission-to-bellhousing bolts to draw or pull the transmission up to the bellhousing, as damage to the pilot bearing and transmission case ears may result.

This kit is designed for use with popular steel scatter shields including QuickTime and Lakewood bellhousings for Ford small block applications paired with the TKX transmission. When installing, ensure the transmission is fully seated by hand against the bellhousing before torquing fasteners to specification. Made in the USA with lifetime tech support from MDL.

Description

Running a classic Ford small block and want flexibility in your clutch setup? This dual-pattern cast iron flywheel eliminates the one-flywheel-per-clutch-size limitation that plagues so many builds. The machined face accepts both the 10" long-style diaphragm clutches found in vintage applications and the 10.4" metric diaphragm clutches used on high-performance '79–'01 Mustangs — so you can start with a stock-style clutch and upgrade to a higher-capacity unit later without pulling the flywheel.

Cast iron construction delivers the rotating mass needed for civilized street manners: smooth idle, progressive engagement, and excellent heat absorption during stop-and-go driving. The 157-tooth ring gear mates with the smaller-diameter bellhousings and starters common on '64–'68 Mustangs and other early Ford small block applications. Precision machining ensures a flat, true friction surface that improves clutch performance and reduces vibration.

The 28oz external imbalance is correct for pre-1981 Ford Windsor and Cleveland engines — 260, 289, 302, 351W, and 351C. (Post-1981 5.0L engines use a 50oz imbalance; verify your engine's balance before ordering.) The 6-bolt crank pattern with 7/16" hardware provides a secure connection to the crankshaft flange.

Compatible with 3-speed, 4-speed, and T5 5-speed manual transmissions. While cast iron flywheels work for light motorsports use, understand the RPM and load limits — billet steel offers better stability for sustained high-RPM or competition applications.

Kit Includes

• Cast iron flywheel with 157-tooth ring gear and dual clutch pattern (10" long / 10.4" metric)
• Pre-installed metric alignment pins for 10.4" clutch pattern
• Clutch alignment pins

Key Features

• Cast iron construction for durability and heat dissipation in street applications
• 157-tooth ring gear for proper starter engagement with small-block Ford bellhousings

• 6-bolt crankshaft mounting pattern matches Ford factory configuration
• 19 lbs flywheel weight provides optimal rotational mass for smooth street driving
• Includes clutch alignment pins for precise pressure plate installation

Description

When Ford switched the 302 to the 5.0L designation in 1981, they also changed the external balance from 28oz to 50oz. That means every '81-'95 5.0L Windsor needs a flywheel with the correct counterweight to maintain proper engine balance and eliminate vibration. This cast iron flywheel delivers exactly that - the right balance for your late-model small-block Ford, with the 157-tooth ring gear that mates to standard small-block bellhousings and starters.

The 10.4" metric clutch pattern is a Ford-specific design that uses alignment pins rather than shouldered bolts to locate the pressure plate. These equalizing pins ensure precise concentricity between the pressure plate and flywheel - critical for smooth clutch engagement and even wear. The metric pattern accommodates modern diaphragm-style pressure plates with 8mm hardware, making it compatible with factory and aftermarket clutch assemblies designed for '83-'95 Mustangs and other 5.0L applications.

Cast iron provides the strength and thermal stability needed for street duty, absorbing and dissipating heat through repeated clutch engagements without the hot spots that can develop on lighter materials. At 19 lbs, this flywheel maintains enough rotational mass for smooth idle and progressive engagement - the kind of drivability you want in a daily driver or weekend cruiser. The 6-bolt crankshaft pattern bolts directly to the factory crank flange with no adapters or modifications required.

Description

When you're building a high-revving Ford small block, your flywheel needs to handle the abuse without becoming a liability. Cast iron flywheels can crack under stress, and non-certified components may not meet the safety standards required at the track. This SFI certified billet steel flywheel delivers the strength and peace of mind that serious builds demand - meeting the rigorous testing standards established by the SFI Foundation for replacement flywheels and clutch assemblies.

The billet steel construction provides superior tensile strength compared to cast alternatives, resisting the centrifugal forces that tear lesser flywheels apart at high RPM. The lightweight design reduces rotating mass for quicker throttle response and faster revs, while maintaining enough thermal mass for consistent clutch engagement. Zero balance (internal balance) simplifies installation on Ford 289, 302, 351W, and 351C engines that use internally balanced rotating assemblies.

Versatility is built into the design with dual clutch bolt patterns. The 10" long pattern accepts 5/16" pressure plate bolts, while the 10.4" metric pattern uses 8mm bolts - and the metric alignment pins come pre-installed so you're ready for either setup. The 6.00" clutch damper counter-bore provides proper clearance for diaphragm-style pressure plates. Note that 157-tooth flywheels require a 3/4" offset starter (often labeled as "automatic" in parts catalogs) for proper ring gear engagement.

Manufactured in the USA with US-milled steel, this flywheel delivers the quality and consistency that American craftsmanship is known for. Whether you're building a weekend warrior or a dedicated track car, SFI certification means this flywheel meets the standards required by most sanctioning bodies for competition use.

Overview

Factory cast iron flywheels have their limits. At high RPM or under aggressive clutch clamping loads, they can develop stress cracks that compromise both performance and safety. This lighten billet steel flywheel replaces that weak link with a material that's fundamentally stronger—billet steel resists cracking and remains stable under the demands of performance driving.

The "lighten" designation refers to strategic material removal that reduces rotational mass without sacrificing structural integrity. At 19 lbs, this flywheel strikes the sweet spot between weight reduction and street manners—light enough for improved throttle response and quicker revs, yet heavy enough to maintain smooth idle characteristics and prevent the stalling issues common with ultra-lightweight aluminum units. The result is a flywheel that feels responsive on throttle tip-in while still delivering civilized behavior in traffic.

Dual clutch bolt patterns machined into the friction surface eliminate fitment guesswork, accepting both 10" and 10.5" pressure plates. The 157-tooth ring gear and 28oz external imbalance match OE specifications for pre-December 1982 small block Fords, ensuring proper starter engagement and crankshaft balance. This flywheel fits Ford 289, 302, and 351W Windsor engines, plus Ford Racing 363ci and 427ci stroker crate motors that use the 28oz balance specification.

Six-bolt crankshaft mounting provides secure attachment, while included clutch alignment pins ensure proper disc positioning during installation. Every flywheel is precision-machined from US-milled steel and manufactured in the USA.

Description

Cast iron flywheels can't handle serious RPM or the repeated abuse of high-horsepower launches. This billet steel flywheel is precision CNC-machined from certified steel, engineered to survive the stress levels that crack and shatter cast units. At 19 pounds, it sheds significant rotating mass compared to heavy OEM flywheels -- translating to quicker revs, faster deceleration between shifts, and reduced parasitic drag on the crankshaft.

The 28oz external balance is critical: all Ford 221, 260, 289, 302, and 351W engines built before December 1982 use a 28-ounce offset balance. Mismatch the balance weight and you'll introduce severe harmonic vibration that punishes bearings and shortens engine life. Post-1981 5.0L High Output engines switched to a 50oz balance -- this flywheel is not for those applications. Match your balance weight to your engine's build date, not the vehicle year.

The dual bolt pattern accommodates both 10" and 10.5" clutch assemblies, giving you flexibility when selecting or upgrading your pressure plate without swapping flywheels. The 157-tooth ring gear is the standard configuration for most small block Ford manual transmission applications in vintage Mustangs, Falcons, Fairlanes, and similar platforms.

SFI certified for competition use where sanctioning bodies require rated flywheel and clutch assemblies. Compatible with Ford small block Windsor engines using the standard six-bolt crankshaft mounting pattern and requiring 28oz external balance.

Description

Factory cast iron flywheels become the weak link when you push serious power through a 5.0L Windsor. Cast iron is prone to stress cracking under repeated high-RPM clutch engagement, and a cracked flywheel at speed is a catastrophic failure waiting to happen. This lightened billet steel flywheel delivers the strength needed for high-performance street builds and competition use while shaving weight to improve engine response.

Billet steel is considerably stronger than cast iron and remains free of the stress cracks that plague factory flywheels under heavy use. The lightened design reduces rotational mass compared to standard-weight flywheels, allowing faster throttle response on acceleration and quicker RPM drop on deceleration - a noticeable improvement whether you're rowing through gears on the street or chasing lap times. The 50oz external balance matches factory 5.0L engine specifications for 1981-1995 applications, ensuring smooth operation with no vibration.

The dual clutch pattern provides flexibility in clutch selection, accepting both 10.5" metric diaphragm pressure plates and 10" long-style setups. Metric alignment pins come pre-installed to ensure proper clutch disc centering during installation. Note that diaphragm clutches require metric pressure plate bolts (MD-403-2003 or MD-403-2003ARP), while the 10" long pattern uses 5/16" bolts (MD-403-2004).

Engineered for Ford small block Windsor engines with 157-tooth starter ring gear applications. Fits all 1981-1995 Ford 5.0L engines requiring 50oz external balance. Proudly made in the USA using US-milled billet steel.

What's Included

• Lightened billet steel flywheel with 157-tooth ring gear

Description

Shed rotational mass without sacrificing reliability. This lightweight aluminum flywheel weighs just 19 lbs compared to heavy cast iron units, helping your engine reach higher RPMs quicker due to reduced rotating mass. That reduced inertia translates to improved throttle response and acceleration - the engine spends less energy spinning up the flywheel and more energy putting power to the wheels.

The riveted steel clutch facing provides superior heat dissipation and wear characteristics compared to bonded surfaces. Unlike cheaper aluminum flywheels that use pressed-on ring gears, this 157-tooth steel ring gear is mechanically fastened to the flywheel body, preventing the ring gear separation failures that can occur under high-stress conditions. The dual bolt pattern accommodates both vintage 10" Long-style and modern 10.4" metric pressure plates with dowel pins - eliminating compatibility guesswork across Ford's clutch evolution.

Engineered specifically for Ford small block 289, 302, and 351W Windsor engines, this flywheel comes standard as zero balance for internally balanced engines. For externally balanced applications, 28 oz or 50 oz counterweight options are available to match your specific crankshaft requirements - pre-1981 302s and all 351Ws use 28 oz imbalance, while 1981+ 302/5.0L engines require 50 oz.

Note: Aluminum flywheels spin up faster but have less stored energy than cast iron, which can make the engine easier to stall at low RPMs. If paired with a dual clutch set, this helps offset some of the characteristics. Aluminum flywheels should never be paired with ceramic or bronze clutches due to the added heat they generate. It is recommended to warm the flywheel before installing on the crank. Not SFI approved - intended for street performance and moderate competition use. Made in the USA with lifetime technical support.

What's Included

• CNC-machined aluminum flywheel body (19 lbs)

• Made in the USA

Description

Ditch the heavy factory cast iron flywheel and drop serious rotating mass from your Ford small block. This aluminum flywheel delivers the weight reduction performance builds demand while maintaining the durability street engines require. Lighter rotating mass means quicker engine response and faster acceleration through the gears - your engine revs up and recovers faster between shifts.

The engineering here focuses on heat management and longevity. The riveted steel clutch facing provides a durable friction surface that handles heat far better than aluminum-on-aluminum contact, preventing warping and premature wear in spirited driving. The high-carbon steel ring gear is riveted to the aluminum body rather than pressed or shrunk on - this prevents the ring gear from walking off the flywheel under the repeated thermal cycling and shock loads of hard use.

This flywheel carries the correct 28oz external balance for pre-1981 Ford 289 and 302 engines, as well as all 351 Windsor engines regardless of year. The 157-tooth ring gear is sized for small bellhousing applications - the compact aluminum bellhousing, not the larger cast iron 164-tooth style. Includes dowel pins for proper clutch alignment with 10.5-inch diaphragm clutch kits.

Installation note: It is recommended to warm the flywheel before installing on the crankshaft for proper thermal expansion and fit. Aluminum flywheels should not be paired with ceramic or bronze-faced clutch discs due to the excessive heat these materials generate. Made in the USA.

What's Included

• Aluminum flywheel with steel clutch facing
• 157-tooth steel ring gear (riveted)
• Clutch alignment dowel pins for 10.5-inch clutch

Key Features

• Riveted steel clutch facing permanently fastened to aluminum body - prevents ring gear separation under high loads
• 157-tooth ring gear for proper starter engagement on 5.0L HO applications
• 50oz external counterweight matches factory balance on 1981-1995 Ford 5.0L HO engines
• 19 lb total weight - reduces rotating mass versus stock cast iron flywheels
• Six-bolt crankshaft mounting pattern for direct replacement installation
• 10.4" metric clutch bolt pattern with alignment pins
• Made in the USA

Description

Cut rotating mass from your 5.0L drivetrain with this aluminum flywheel, purpose-built for 1981-1995 Ford 5.0L HO engines. Weighing just 19 lbs, it delivers noticeably quicker throttle response and faster RPM changes compared to stock cast iron units - ideal for road racing, autocross, and spirited street driving where nimble engine response matters more than low-RPM grunt.

The critical engineering detail is the riveted steel clutch facing. Unlike cheaper aluminum flywheels that rely on shrink-fit alone, this design permanently fastens the steel ring gear to the aluminum body using mechanical fasteners. This prevents the ring gear from walking or separating under hard launches and high-heat clutch engagement - a common failure mode when differential thermal expansion rates cause the steel ring gear to loosen on an aluminum body.

The 50oz external imbalance is factory-correct for Ford 5.0L HO engines from 1981-1995, ensuring smooth operation without vibration. The 157-tooth ring gear matches OEM specifications for proper starter motor engagement. Six-bolt crankshaft attachment follows Ford's original pattern, and the 10.4" metric clutch bolt pattern with alignment pins accommodates most performance clutch upgrades.

Important: Aluminum flywheels reduce stored rotational energy, which can make low-RPM driving feel less forgiving - they're easier to stall from a stop. This flywheel should not be paired with ceramic or bronze clutch discs, as the excessive heat generated can damage the aluminum body. It is recommended to warm the flywheel before installing on the crankshaft for optimal fit. Made in the USA.

What's Included

• Aluminum flywheel with riveted steel clutch facing
• Clutch alignment pins

When you've built serious power but need a clutch that remains civilized on the street, the McLeod RST twin disc clutch kit delivers an economically priced solution for high-horsepower Ford applications. This kit solves the fundamental problem of single-disc clutches that either slip under power or become unbearably harsh for daily driving - without requiring you to purchase a new flywheel.

Capable of handling 800 horsepower, this clutch manages extreme power while remaining street-friendly. The twin-disc design spreads clamping loads across two organic friction surfaces, reducing pressure plate spring tension compared to equivalent single-disc setups. Organic-faced twin sprung hub friction discs provide smooth engagement with soft pedal effort and excellent release characteristics, making this ideal for enthusiasts who demand performance without sacrificing driveability.

The small ring adapter configuration works with Ford 157T flywheel bolt patterns. The 26 x 1-1/8" input spline accommodates transmissions like the TKO-500/600, TKX, and T56 Magnum. McLeod's patent-pending adapter ring ensures proper pressure plate positioning and prevents the binding issues common with universal adapters. This kit requires your existing flywheel, which must be properly resurfaced before installation. Flywheel surface must have a coarse texture from a stone grinder - if you run your fingernail across it, the texture should catch your nail.

Compatible with Ford applications using 10" Long bolt patterns with 8mm hardware for 10.5" bellhousing configurations. Note: This clutch is designed for high-horsepower street use and is not intended for competition environments. Made in the USA.

Description

When your build pushes past 500hp and you still want to drive it on the street, single-disc clutches start showing their limits. The McLeod RXT twin disc clutch kit delivers 1,000hp holding capacity in a package that maintains street manners - soft pedal effort, smooth engagement, and the kind of durability that lets you drive to the track, run quarter-mile passes, and drive home without drama.

The engineering centers on dual ceramic friction discs mounted to a Blanchard ground floater plate. The ceramic facings provide slightly aggressive engagement with excellent release characteristics - enough grip for serious power without the on-off grabbiness that makes some racing clutches miserable in traffic. The floater plate distributes heat across both friction surfaces, preventing the hot spots that kill single-disc setups under sustained abuse. McLeod's diaphragm pressure plate maintains consistent clamping force throughout the disc's lifespan while actually delivering lighter-than-stock pedal effort.

This kit uses McLeod's patent-pending large gold metric adapter ring, eliminating the need for a dedicated flywheel. The adapter ring bolts directly to flat-style metric flywheels found on Ford 164T Modular engines (4.6L, 5.0L Coyote, 5.4L) and GM 168T LS1/LS6 applications. Critical note: this kit will NOT fit factory 2011-17 Coyote flywheels, recessed LS2/LS3/LS7 flywheels, or flywheels with crank reliefs larger than 6.250 inches in diameter. The 1-1/8-inch x 26-spline input shaft fits T-45, TR-3650, T-56, TR-6060, and TREMEC Magnum transmissions with 26-spline inputs.

Break-in requires 500-750 miles of stop-and-go city driving to properly seat the friction surfaces - no drag racing or dyno pulls until you've actuated the clutch 1,200-1,500 times. Always resurface the flywheel with a coarse stone-ground finish, replace the pilot bearing, and verify bellhousing alignment during installation.

Description

Converting your '61-'66 Ford F-Series to modern hydraulic clutch actuation typically means fighting heavy pedal pressure and firewall interference. Traditional hydraulic conversions bolt a 3/4" or 7/8" bore master cylinder directly to the pedal with a short 1" stroke--this creates excessive pedal effort, requires mounting the cylinder higher than the stock clutch rod hole, and causes interference with the firewall and pedal assembly. The LF Series solves all of these problems with a precision-engineered linkage system that transforms how hydraulic clutch actuation works in your classic truck.

The engineering breakthrough is MDL's mechanical pedal linkage. Instead of mounting the master cylinder directly to the pedal, this linkage creates leverage that matches pedal travel with the master cylinder's long 1.4" stroke. The result is dramatically reduced pedal effort while using the stock clutch rod hole location. The 0.700" bore paired with that long stroke generates sufficient fluid volume to actuate most aftermarket external slave cylinders and internal hydraulic release bearings without requiring excessive pedal travel.

The remote silver billet aluminum reservoir mounts separately on the firewall, eliminating the bulk of integral reservoir designs and providing a clean, professional installation. The system uses standard DOT 3 or 4 brake fluid and includes MDL's exclusive One-Man-Bleeder kit for straightforward bleeding without a helper. If your clutch pedal bottoms out or feels spongy, check the master cylinder throw distance (should be 1.4") and adjust the clevis and pedal height as needed.

Description

Converting your 1967-1972 Ford F-Series to modern hydraulic clutch actuation eliminates the binding, constant adjustment, and heavy pedal effort that plague mechanical linkages in these classic trucks. The MDL LF Series Master Kit addresses the unique challenges of F-Series installations—starting with the notoriously thin factory firewall that flexes under pedal pressure and robs you of consistent clutch feel.

The engineering centers on a firewall support bracket that ties the firewall to the dash structure, creating a rigid mounting platform that eliminates flex entirely. The 0.700" bore combined with 1.4" stroke delivers 0.539 cubic inches of fluid displacement per stroke—optimal volume for most aftermarket slave systems while the small bore and long stroke design keeps pedal effort light and controllable. The direct pedal linkage bypasses stock clutch rod complexity while preserving original pedal mounting points.

The silver billet aluminum remote reservoir mounts cleanly away from the firewall, simplifying both installation and ongoing maintenance access. The system runs on standard DOT 3 or DOT 4 brake fluid with no need for high-temperature formulations. Each kit includes comprehensive instructions and MDL's unique One-Man-Bleeder Kit that eliminates the need for an assistant during system bleeding.

This kit relies on factory components being in good working order—any modifications or damage to the firewall, pedal, or pedal hanger will affect master cylinder performance. Made in the USA with lifetime technical support included.

Description

External slave cylinders create clearance headaches and bellhousing compatibility issues that derail Ford TKO and TKX swaps. The Tilton 6000 Series Hydraulic Release Bearing eliminates those problems entirely. This internal hydraulic design slips directly over the transmission's bearing retainer - no machining, no adapter plates, no fighting for space. The result is a clean installation that works with most bellhousings, including original 4-speed and big block bells that external slaves can't accommodate.

Tilton builds this bearing to race-proven standards. The billet aluminum body and piston are precision-machined in-house at Tilton Engineering, then fitted with a high-temperature mono-seal that incorporates a quad tensioner to maintain proper seal tension under extreme conditions. The constant contact design keeps the bearing face against the pressure plate fingers at all times - no gap to manage, no adjustment as the clutch wears. Pedal feel stays consistent from fresh install through the clutch's entire service life.

The stainless steel threaded adjustment sleeve delivers nearly 1.25" of height adjustability, accommodating bearing heights from 1.77" to 3.00" to work with a wide range of clutch configurations. The flat face bearing design with 1.71" to 3.03" contact diameter is engineered for 8.5" to 11" bent-finger and lever-type pressure plates. With 0.7" of piston travel, this bearing handles aggressive clutch setups without running out of stroke.

Compatible with Ford TKO and TKX transmissions with 1.430" bearing retainer guide tube diameter. Will not work with big-input Toploaders. For a complete hydraulic clutch system, pair with an MDL LF Series Master Clutch Kit and a steel braided line of appropriate length (24" recommended for most applications).

Description

Factory plastic clutch lines deteriorate under heat and age, leading to spongy pedal feel and inconsistent clutch engagement. This premium stainless steel braided hydraulic line eliminates that weak link with high-strength construction rated for racing and high-heat applications. The Teflon inner lining delivers chemical compatibility with all brake fluids while providing smooth, unrestricted fluid flow that translates directly to crisp pedal response.

The stainless steel braid resists expansion under pressure—a critical factor in hydraulic clutch performance. Unlike rubber lines that balloon slightly under load, braided stainless maintains consistent internal volume for immediate, predictable clutch actuation. The clear plastic outer coating shields the braid from road debris and corrosion while preserving the polished stainless appearance gearheads expect in a quality engine bay.

This is the same 30-inch hydraulic line included in MDL's LF Series slave cylinder kits, proven across thousands of transmission swaps from mild street builds to extreme-duty track cars. Straight -4AN female fittings on both ends provide universal compatibility with hydraulic clutch systems, master cylinders, and slave cylinders across Ford, GM, and Mopar applications. Whether you're completing a TREMEC five or six-speed swap or upgrading your existing hydraulic clutch setup, this line delivers the durability and pedal feel your build demands.

Description

Crown Vic front clip conversions deliver modern independent front suspension and rack-and-pinion steering to classic Ford F-Series trucks, but they create a significant challenge: the driveline now sits centered on the frame rather than offset like the factory setup. The OEM transmission crossmember wasn't designed for this geometry, leaving builders to fabricate solutions or compromise on driveline angles. This Stifflers tubular transmission crossmember solves that problem with a purpose-built design for 1948-1979 Ford F-1, F-100, and F-150 trucks running 34-inch wide frame rails with Crown Vic clip conversions.

The single tube construction offers far greater stiffness and strength than the stamped steel factory crossmember, eliminating flexing under power that causes driveline vibration and premature wear on U-joints and transmission mounts. Bolt-on mounting brackets provide complete adjustability over driveline height and angle without any welding or fabrication - critical when adapting modern transmissions to vintage chassis geometry. The custom adjustable transmission mount allows further fine-tuning to dial in the perfect transmission position for smooth, vibration-free operation.

Stifflers engineered this crossmember specifically for the centered driveline position that Crown Vic clip swaps create. Rather than trying to modify a Mustang crossmember or fabricate a one-off solution, you get a bolt-in piece that addresses the unique requirements of this popular conversion. The powder-coated finish protects against corrosion, and the entire design keeps weight to a minimum while delivering maximum strength.

This crossmember works with virtually any transmission you might install in your F-Series build, including AOD, AODE, 4R70W, C4, C6, T-5, T-45, T-56, TKO, 3550, 3560, TH350, TH400, and Powerglide units. Designed and manufactured in the USA by Stifflers Chassis & Suspension - a company founded by former IndyCar engineers who bring professional-level engineering to enthusiast suspension and drivetrain components.

What's Included

• Stifflers tubular transmission crossmember with powder-coated finish

Description

Ford Hi-Boy trucks present unique shifter challenges with their divorced transfer case configurations and twin-stick setups. The separate transmission and transfer case shifters require a boot that accommodates multiple openings while sealing properly against dust, moisture, and debris. Standard single-opening boots simply cannot handle the Hi-Boy layout - this purpose-built shifter boot solves that problem for transmission and twin-stick transfer case applications in Ford 4WD builds, including TKX transmission swaps.

The engineering focuses on durability where it matters most. Hand-sewn construction uses US-sourced high-quality automotive textured vinyl rather than the stiff, heavy marine vinyl that cracks and splits under hood heat and constant flexing. The material formulation resists oil contamination and sulfide exposure - critical when dealing with transmission fluid and exhaust gases that plague floor-mounted shifters in working trucks. Mildew resistance prevents the deterioration common in moisture-prone areas around the transfer case tunnel.

Safety compliance meets Motor Vehicle Safety Standard 302 for flammability, a critical consideration for floor-mounted applications near the drivetrain. The included stainless steel trim ring provides both edge protection and a finished appearance that matches the utilitarian aesthetic Hi-Boy builders demand. Whether you are restoring a numbers-matching truck or modernizing with a TKX swap, this boot delivers the fit and durability the application requires.

Made in the USA with quality materials and hand-sewn craftsmanship - not a mass-produced overseas part that will deteriorate in a season.

• Direct fit for Ford T5, T45, TKO, TKX, and T56 Magnum transmissions
• Precision-molded construction for smooth, reliable operation

Description

When you swap to a 5- or 6-speed transmission, your original speedometer gear won't work with the new final drive ratio, throwing off your speedometer readings. This 16-tooth driven gear provides the correct gear ratio match to restore accurate speedometer operation in Ford T5, T45, TKO, TKX, and T56 Magnum applications.

Selecting the correct driven gear depends on your rear axle ratio and tire diameter. The wine-colored housing provides instant visual confirmation of the 16-tooth count during installation and future service, eliminating guesswork when fine-tuning your speedometer calibration. Each tooth change adjusts the speedometer reading approximately 4-5 mph, so selecting the right gear for your combination is critical.

This is the correct driven gear for all Ford T5, T45, TKO, TKX, and T56 Magnum transmissions. Whether you're building a street machine that sees daily driving or a weekend cruiser that needs reliable instrumentation, this precision-molded gear delivers smooth, accurate speedometer operation mile after mile.

What's Included

• 16-tooth speedometer driven gear with wine-colored housing

Key Features

• 17-tooth driven gear with white color coding for easy identification
• Direct fit for Ford TREMEC transmissions: T5, T45, TKO, TKX, and T56 Magnum
• Precision-molded plastic construction for smooth, quiet operation
• Lower tooth count for higher axle ratios and/or taller tires
• Works with cable-driven mechanical speedometer systems

Description

Swapping to a 5 or 6-speed TREMEC transmission changes your final drive ratio, which means your factory speedometer gear combination no longer reads accurately. This 17-tooth white driven gear lets you recalibrate your mechanical speedometer to match your new drivetrain setup.

Speedometer driven gear selection depends on four variables: drive gear tooth count (on the output shaft), driven gear tooth count, tire diameter, and axle ratio. The 17-tooth count is typically paired with lower-numerical axle ratios or taller tires. Use a speedometer gear calculator to determine the correct tooth count for your specific combination of drive gear, rear end ratio, and tire height.

The white color coding makes this gear instantly identifiable, both in your parts bin and during installation. This precision-molded plastic gear meshes smoothly with the transmission's output shaft drive gear, delivering reliable operation without the noise or wear issues that can plague poorly-manufactured replacements.

This driven gear fits all Ford TREMEC transmissions including T5, T45, TKO, TKX, and T56 Magnum. Whether you're building a classic Mustang, Fairlane, or any Ford platform with a mechanical speedometer, this gear helps dial in accurate speed readings after your manual transmission conversion.

• 17-tooth speedometer driven gear, white plastic

Speedometer Driven Gear | Ford T5/T45/TKO/TKX/Magnum | 18-Tooth Yellow

Key Features

• 18-tooth driven gear for speedometer calibration on Ford-pattern transmissions
• Yellow color-coded for quick identification during installation and service
• Fits Ford T5, T45, TKO, TKX, and T56 Magnum transmissions
• Precision molded for accurate tooth engagement and long service life
• Direct replacement--installs into existing speedometer drive housing without modification

Description

When you swap in a 5- or 6-speed manual transmission, your factory speedometer gear ratio goes out the window. The new transmission's final drive ratio won't mesh with your original speedo gear, leaving your speedometer reading inaccurately--sometimes wildly so. This 18-tooth yellow driven gear lets you dial in the correct speedometer calibration for your specific tire size and rear axle ratio combination.

This driven gear fits the full range of Ford-pattern TREMEC transmissions: T5, T45, TKO, TKX, and T56 Magnum. The industry-standard yellow color coding makes identification simple--no guessing which tooth count you're running when it's time for service or recalibration after a gear ratio change. The precision-molded construction ensures consistent tooth engagement with the drive gear for accurate, reliable speedometer readings mile after mile.

Installation is straightforward--the gear slides directly into the transmission's speedometer drive housing. If your speedometer calibration calculations call for more than 21 teeth (the maximum available driven gear size), you'll need to reduce the drive gear tooth count instead. Use a speedometer gear calculator with your tire diameter, axle ratio, and transmission drive gear tooth count to determine the correct driven gear for your application.

Kit Includes

• 18-tooth yellow speedometer driven gear

Key Features

• 19-tooth driven gear for precise speedometer calibration
• Pink color-coded for instant tooth count identification
• Fits Ford T5, T45, TKO, TKX, and TREMEC T56 Magnum transmissions
• Essential for correcting speedometer accuracy after gear ratio or tire size changes
• Precision molded construction for reliable, long-lasting operation

Description

When you swap transmissions, change rear axle ratios, or bolt on different tire sizes, your speedometer no longer reads correctly. This 19-tooth driven gear lets you recalibrate for accurate readings by changing the gear ratio between your transmission's output and the speedometer cable. It's the driven gear -- the one that mounts to the speedometer cable end and inserts into the transmission tailhousing.

The pink color follows Ford's standardized identification system, making it easy to confirm the tooth count at a glance when you're sorting through your parts bin or comparing against your current setup. If your speedometer reads too fast with your current gear, stepping up to this 19-tooth unit will slow the reading. Each additional tooth changes the speedometer reading by approximately 5-6%. If you need an even higher tooth count, 21-tooth is the largest available in the driven gear; beyond that, you'll need to reduce the drive gear size instead.

This gear fits all Ford T5, T45, and Ford T56 transmissions, as well as all TREMEC TKO, TKX, and T56 Magnum units. Installation is straightforward: remove the speedometer cable from the tailhousing, swap the driven gear, and reinstall.

What's Included

• One 19-tooth speedometer driven gear (pink)

Key Features

• 20-tooth driven gear for precise speedometer calibration
• Black color-coded for easy identification per Ford specification
• Fits Ford T5, T45, Ford T56, TREMEC T56 Magnum, TKO, and TKX transmissions
• Direct replacement for worn or incorrect factory gears
• Precision-molded plastic construction for durability and accurate engagement

Description

Transmission swaps and axle gear changes throw off speedometer accuracy - this 20-tooth driven gear gets your needle reading true again. When you install a five- or six-speed manual, the final drive ratio no longer matches your original speedometer gear, leaving you guessing at your actual speed. The correct driven gear restores accurate instrumentation so you know exactly how fast you're going.

This precision-molded driven gear is color-coded black for 20-tooth identification, following the standard Ford speedometer gear system. It pairs with the 7-tooth drive gear found on TREMEC TKO 500, TKO 600, TKX, and T56 Magnum transmissions to dial in speedometer accuracy for specific tire and axle combinations. Calculate your correct tooth count based on your tire diameter and rear axle ratio - if your math points to 20 teeth, this is your gear.

Note that 21 tooth is the largest driven gear size available for these applications. If your calculations call for a larger tooth count beyond 21, reducing the drive gear size provides the necessary calibration adjustment. Compatible with all Ford T5, T45, Ford T56, TREMEC T56 Magnum, and all TKO and TKX variants.

What's Included

• One 20-tooth driven speedometer gear (black)

Key Features

• 21-tooth red gear follows Ford's factory color-coding system for manual transmissions
• Largest standard driven gear tooth count available for maximum speedometer correction
• Fits all TREMEC transmissions using Ford-style speedometer systems: T5, T45, TKO, TKX, and T56 Magnum
• Precision molded nylon construction for smooth, quiet operation and long service life
• Direct drop-in replacement--no modifications required

Description

Swapping to a 5 or 6-speed TREMEC transmission changes your final drive ratio, which throws off your factory speedometer calibration. This 21-tooth red driven gear lets you recalibrate your mechanical speedometer to read accurately with your specific tire size and rear axle ratio combination--no electronic tuner required.

Ford has used a consistent color-coding system for manual transmission speedometer gears since the 1960s: 16-tooth wine, 17-tooth white, 18-tooth yellow, 19-tooth pink, 20-tooth black, and 21-tooth red. As the largest tooth count in the standard range, this red 21-tooth gear provides maximum correction for applications with taller tires or numerically higher axle ratios. Each tooth of difference adjusts your speedometer reading approximately 5-6%, so selecting the correct count is critical for accuracy.

The driven gear installs into the speedometer housing on the tailshaft of your transmission, where it meshes with the drive gear on the output shaft. TKO, TKX, and T56 Magnum transmissions come from the factory with a 7-tooth drive gear, making this 21-tooth driven gear the correct starting point for common combinations like 3.55 or 3.73 rear gears with 26-inch or taller tires. Use a speedometer gear calculator with your actual tire diameter and axle ratio to confirm the correct tooth count for your build.

This gear is compatible with Ford T5, T45, TKO, TKX, and T56 Magnum transmissions. The driven gear works with both cable-driven and VSS-equipped speedometer systems--just swap it into your existing housing.

What's Included

• 21-tooth red speedometer driven gear (precision molded nylon)

Key Features

• Secures driven speedometer gear for proper placement and operation in Ford T5 transmissions
• Direct replacement for original clips that have become brittle from heat exposure
• Essential component for automatic-to-manual conversions where no clip exists
• Compatible with all Ford T5 transmissions

Description

Clip-style speedometer gears require a retaining clip to lock the driven gear securely in the transmission housing, and this replacement clip delivers the secure fit your Ford T5 needs. Without a properly functioning clip, the driven speedometer gear can back out of the housing during operation, causing inaccurate speedometer readings and potential fluid loss.

Original retaining clips often become brittle after years of heat cycling in the transmission environment. If you're servicing your Ford T5, T45, T56, TKO/TKX, and Magnum speedometer gear or coming from an automatic transmission that didn't use a mechanical speedometer setup, a new retaining clip ensures your driven gear stays exactly where it needs to be. This is an inexpensive detail that makes the difference between a speedometer that works reliably and one that gives you trouble down the road.

This clip is the correct fitment for all Ford T5 transmissions and works with standard Ford-style driven speedometer gears. Keep one on hand whenever you're doing speedo gear service work.

What's Included

• One (1) retaining clip for Ford driven speedometer gear

Key Features

• 16-pulse Hall effect sensor delivers 16,000 pulses-per-mile output for accurate electronic speedometer calibration
• Direct bolt-in fitment for Ford gear drive TKO and TKX transmissions
• Three-wire design with included 10-foot pigtail harness for flexible routing and clean signal transmission
• Allen-head mounting bolt provides body clearance in tight transmission tunnel applications
• Uses standard T5 driven speedometer gears - no adapter required for low-profile installation.
• Compatible with Ford T-5, T-45, TR3550, 5-speed and 6-speed Ford T-56, and Magnum transmissions (requires Ford-driven speedometer gears and retainer clip)

Description

Swapping to a TKO or TKX five-speed means ditching the factory mechanical speedometer cable - but your electronic dash, engine management system, or cruise control still needs a reliable speed signal. This digital speedometer sensor plugs directly into the Ford-style VSS port on your TREMEC transmission's passenger-side tail housing and delivers a clean 16-pulse signal that works with the industry-standard 16,000 pulses-per-mile input most aftermarket speedometers and ECUs expect.

The three-wire Hall effect design provides a stable square wave output that won't degrade over long wire runs. The included 10-foot pigtail harness gives you plenty of length to route wiring cleanly through the tunnel and up to your dash or ECU, with a three-pin connector for easy hookup. The Allen-head mounting bolt is a thoughtful detail - standard hex-head fasteners can interfere with the sensor body in tight quarters, so this design ensures proper installation without clearance issues.

Beyond the TKO and TKX, this sensor also works with T-5z 5-speed and 6-speed Magnum transmissions when paired with Ford-driven speedometer gears and a retainer clip. Note that it does not fit Super Magnum, Magnum XL, or Magnum F transmissions - those use a different VSS configuration. If you're running a Dakota Digital, Classic Instruments, Auto Meter, or other programmable electronic speedometer, this sensor's 16,000 PPM output drops right into their standard calibration range.

What's Included

• 16-pulse digital speedometer sensor with three-pin connector
• 10-foot three-wire pigtail harness
• Allen-head mounting bolt

This Neapco 31-spline forged steel slip yoke delivers the strength and precision fit required for Ford TKO, C6, and FMX transmissions, providing a direct-fit solution for street performance builds.

Forged steel construction eliminates the porosity and stress risers inherent in cast yokes. The result is a stronger, more consistent part that handles torque loads without cracking or deformation. The 1310 Series U-joint is rated for 400 lb-ft of continuous torque and 800 lb-ft short-duration loads--making this combination well-suited for street-driven cars producing up to approximately 500 hp, provided traction is managed with street tires rather than slicks.

Neapco's precision broaching process produces tight-tolerance spline fits that mate smoothly with the transmission output shaft. This accuracy, combined with reduced end play in the universal joint, minimizes driveline vibration and extends component life. The outside snap ring design allows for straightforward U-joint service when maintenance is eventually needed.

This slip yoke fits Ford transmissions with 31-spline output shafts, including the Ford TKO, C6 automatic, and FMX automatic. If your application requires higher torque capacity, consider upgrading to a 1330 or 1350 Series yoke and matching driveshaft components.

The increased torque from a modern 5-speed or 6-speed manual transmission demands a properly matched slip yoke that can handle the load without becoming a weak link in your driveline. This 31-spline slip yoke solves that problem with the proven 1330 series dimensions and D550 ductile iron construction.

The forged steel construction provides the tensile strength needed for high-torque applications while maintaining the precise tolerances required for smooth, vibration-free operation. The 1330 series u-joint dimensions - 3-5/8" overall width with 1-1/8" bearing caps - deliver more driveline angle capability than the smaller 1310 series while keeping overall packaging compact. Outside snap rings secure the u-joint caps, making future service straightforward without specialized tools.

The 31-spline internal configuration directly matches the output shaft splines on TREMEC TKX, TKO, and Magnum transmissions, as well as some T56 variants, Ford C6 automatics, and FMX transmissions. Built by Neapco to OEM standards, this slip yoke bridges the gap between your transmission upgrade and your existing driveshaft, accepting standard 1330-series u-joints for flexibility in choosing greaseable or sealed units based on your application.

Description

Upgrading to a TREMEC transmission puts serious torque capacity in your drivetrain, but your existing slip yoke often becomes the weak link. TREMEC TKO, TKX, and Magnum transmissions all feature a 31-spline output shaft that requires a matching slip yoke to handle the increased power these transmissions deliver. This MDL slip yoke solves that problem with cast steel construction and 1350 series U-joint capacity.

The 31-spline output shaft on TREMEC performance transmissions uses the same diameter as Ford C6 automatics—a proven design that has been handling serious torque for decades. The 1350 series U-joint provides a 1-3/16" cap diameter and 3.625" overall width, delivering significantly more strength than the smaller 1310 series joints found in many factory drivelines. When you're pushing 600 lb-ft of torque capacity through a TKO or TKX, you need driveline components that can keep up.

This slip yoke is designed for Ford applications but works with any TREMEC transmission featuring the standard 31-spline output shaft, including the TKO-500, TKO-600, TKX, and T56 Magnum. Whether you're building a street machine that sees weekend abuse or a dedicated track car, this yoke provides the strength and reliability your upgraded drivetrain demands.
