Overview

If you are making over 400 horsepower and need to upgrade from a tired four-speed, the TREMEC TKX delivers everything your Ford build demands. Unlike repurposed OE transmissions, the TKX was engineered from the ground up specifically for the aftermarket - designed to handle serious power while fitting into classic Mustangs and other vintage Fords without the floor surgery typically required by larger transmissions.

The end-loaded case design is the key to the TKX's compact footprint. TREMEC eliminated the traditional side-loading architecture, resulting in a slimmer, more streamlined case that clears tight transmission tunnels. The three-piece ribbed aluminum housing (main case, intermediate plate, and rear extension) delivers outstanding structural stiffness while reducing overall weight to just 99 lbs dry. Fewer case seams mean fewer potential leak points, and gaskets at all flanges simplify installation.

Inside, the TKX punches well above its weight class. Wide gear widths increase gear life and torque capacity, while tapered roller bearings on the input, output, and countershafts reduce noise and improve durability. Caged needle bearings on the mainshaft optimize performance at all gear positions. The internal three-rail shift system provides robust, precise gear engagement, and the rear mainshaft support bushing has been relocated closer to the gearbox for improved support. Hybrid triple-cone synchronizers made from sintered bronze and carbon deliver smooth, notch-free shifts even at 7,500 RPM.

This close-ratio configuration (2.87 first gear with 0.68 overdrive) keeps your engine in its powerband during spirited driving while dropping highway RPM for improved fuel economy and reduced wear. Short input shaft kits are available for Ford 3-speed and 4-speed bellhousing applications. Made from 100% brand-new OEM-quality components.

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.

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

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.

Kit Includes

• Billet steel flywheel with 157-tooth ring gear
• Pre-installed 10.4" metric clutch alignment pins

Key Features

• Lighten billet steel construction resists stress cracking and handles higher RPM loads than cast iron
• 157-tooth ring gear with 28oz external imbalance for pre-1982 Ford 289/302/351W engines
• Dual clutch bolt patterns accommodate both 10" and 10.5" pressure plates
• 19 lb weight balances reduced rotational mass with smooth street drivability
• 6-bolt crankshaft mounting pattern; clutch alignment pins included
• Compatible with Ford Racing 363/427ci crate engines
• Precision-machined from US-milled steel; Made in the USA

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.

What's Included

• Lighten billet steel flywheel (19 lbs)
• 157-tooth ring gear (installed)

Billet Steel SFI Flywheel | Ford Small Block | 157 Tooth | 28oz | 10"-10.5" Clutch

Key Features

• Lightened billet steel construction -- stronger than cast iron with reduced rotational mass at just 19 lbs
• SFI certified for racing sanctioning bodies requiring SFI-rated drivetrain components
• 28oz external balance for pre-1982 Ford 221, 260, 289, 302, and 351W engines
• Dual bolt pattern accepts both 10" and 10.5" clutch assemblies
• 157-tooth hardened ring gear for proper starter engagement
• Six-bolt crankshaft mounting pattern -- standard Ford small block fitment
• CNC-machined friction surface for consistent clutch engagement
• Made in the USA with lifetime technical support from MDL

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. Made in the USA with lifetime technical support from MDL.

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
• Metric clutch alignment pins (pre-installed)

Key Features

• Lightweight aluminum construction at 19 lbs - significantly lighter than cast iron for faster engine response
• Riveted steel clutch facing for superior durability and heat dissipation
• Dual clutch bolt pattern: 10" Long and 10.4" metric with dowel pins for maximum compatibility
• Zero balance configuration standard; can be ordered with 28 oz or 50 oz counterweight options
• 157-tooth steel ring gear mechanically fastened to flywheel body - prevents ring gear separation
• 6-bolt crankshaft mounting pattern for Ford small block engines
• Made in the USA

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.

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

Description

When you need more holding power than a full-Kevlar disc can deliver but want to preserve some street manners, the Superior Kevlar/Ceramic clutch assembly is the answer. This hybrid design places Kevlar on the flywheel side for smooth engagement and extended life, while the ceramic facing on the pressure plate side delivers the aggressive bite and heat resistance demanded by drag launches and high-RPM road racing shifts. Great for 1986-1995 Ford applications running the 10.4" metric bolt pattern.

Ceramic friction material works harder as temperatures climb--the iron content in MDL's ceramic compound actually increases friction under heat, making this clutch stronger during abuse rather than weaker. That's why ceramic is the go-to choice for higher horsepower builds, quick shifts in road racing, and hard-launching drag cars. When a larger diameter disc isn't an option, the higher coefficient of friction delivers more holding power from the same surface area and clamp load.

Every Superior clutch assembly is hand-built in MDL's Caldwell facility using double-riveted construction and exacting quality standards. Each unit is checked and double-checked for accuracy before it ships, so you receive a ready-to-install premium product right out of the box. The 26-spline, 1-1/8" hub fits transmissions like the TREMEC TKO, TKX, or any 26-spline T5 variant.

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. This kit does not include a pilot bearing or throwout bearing.

• 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.

• 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, T-45, T-56, 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

• 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.

• Resists harmful sludge formation with seal conditioning to guard against leaks
• Compatible with T5 World-Class, T45, TR3650, TKX, T56, TR6060 and Magnum transmissions

Description

Modern manual transmissions feature complex internal components -- multiple gear sets, clutch packs and narrow oil passageways -- that demand a steady supply of high-quality fluid to function properly. Without it, wear and sludge formation can lead to reduced performance and even catastrophic failure requiring thousands of dollars in repairs. This AMSOIL Synthetic Automatic Transmission Fluid delivers the Dexron III specification required by TREMEC transmissions while providing protection that exceeds conventional fluids.

In both normal and severe service, this synthetic ATF resists wear to the transmission's valve body, gears, clutch plates and synchronizers, helping your TREMEC achieve long service life. The thermally stable formulation guards against the harmful effects of thermal breakdown in elevated heat conditions, while resisting heat-related evaporation and viscosity loss to keep internal components clean and protected.

Formulated with friction modifiers that promote fast, smooth clutch engagement, this fluid delivers responsive shift feel and efficient torque transfer. It remains fluid in sub-zero temperatures, resisting thickening and flowing quickly for reliable shifts during cold starts. The excellent low-temperature fluidity also maximizes fuel efficiency. Seal conditioners help guard against leaks at input shaft seals and other critical points.

TREMEC TKX transmissions use Dexron III or Dexron III/Mercon specification ATF fluid, and Dexron III ATF is also recommended for T56 and TR3650 models. The T5, TKO and TKX five-speed transmissions require approximately 2.75 quarts, while six-speed Magnum transmissions require approximately 3.45 quarts. TREMEC recommends changing fluid after the initial 500-1000 mile break-in period, then every 30,000 miles thereafter.

What's Included

• One (1) quart bottle AMSOIL Synthetic Automatic Transmission Fluid (Dexron III compatible)

Key Features

• OE-style replacement compatible with C4DZ-6068-A applications
• Precision-welded steel bracket with protective coating for corrosion resistance
• Rubber insulator dampens vibration without transmitting harshness to the chassis
• Direct fit for T5, TKO, TKX, and Toploader manual transmissions, plus C4 automatics
• Compatible with mid-1960s and later Ford vehicles and 1977-up F-Series trucks
• Made in the USA

Description

Maintaining proper driveline angle is critical for smooth operation, reduced vibration, and long-term drivetrain component life. Whether you're swapping to a modern overdrive transmission or replacing a worn-out factory mount, this precision-engineered transmission mount delivers OE-quality fit and durability for multiple Ford transmission applications.

The precision-welded steel bracket provides a solid, secure mounting point while the protective coating guards against corrosion over the long haul. Unlike polyurethane mounts that can transmit drivetrain vibration directly into the chassis and cabin, this mount uses a rubber insulator that effectively dampens vibration for a quieter, more comfortable driving experience. It's the factory-style approach for a reason.

This mount fits T5, TKO, TKX, and Ford Toploader 4-speed manual transmissions as well as C4 automatics. Application coverage includes mid-1960s and newer Ford vehicles plus 1977-up F-Series trucks. Requires MD-201-Mount 1101 hardware kit, sold separately.

Made in the USA with quality materials and precision manufacturing for applications demanding proper fit and reliability.

Description

When you upgrade to a high-performance transmission or build serious horsepower, your factory driveshaft becomes a weak link. This custom steel driveshaft replaces undersized OEM tubing and economy-grade components with engineering designed for real power. Built to order with your exact measurements, it delivers the strength and precision your driveline demands.

The foundation is DOM (Drawn Over Mandrel) 3-inch steel tubing - 15% stronger than OEM construction. DOM tubing is drawn over a precision-machined mandrel during manufacturing, producing straighter, more concentric material with tighter tolerances than standard electric-welded tube. This precision matters at high RPM, where even minor imbalances create vibration and accelerate component wear.

The 31-spline forged steel slip yoke mates to transmissions including TREMEC TKO-500, TKO-600, T56 Magnum, Ford C-6, T-45, 3550, 3650, FMX, and Top Loader units. The 1330 series U-joints feature 1.062-inch cap diameter and 3.625-inch width, offering greater operating angle capability than 1310 series while maintaining compatibility with common pinion yokes. Every shaft is professionally balanced for smooth operation across the entire RPM range.

This is a custom-built component requiring accurate measurements from your completed vehicle.
