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.

Description

Adding a modern overdrive transmission behind your Ford FE big block means solving the bellhousing puzzle - and cheap adapters just create new problems. The QuickTime RM-6056 delivers the dimensional precision that keeps your drivetrain aligned and your clutch releasing cleanly, whether you're bolting up a TKO, TKX, T5 Mustang, or TR3550 behind your 352, 360, 390, 427, or 428 FE.

QuickTime's proprietary spin-forming process creates a fundamentally different bellhousing than competitors. Where others stamp or roll their cones - introducing distortion and stress risers - QuickTime spins theirs from high-grade steel that work-hardens to over 80,000 PSI. That's more than twice the strength of conventional steel bellhousings. The result is a cone that maintains perfect dimensional stability through the entire RPM range, eliminating the flex that causes accelerated input bearing wear, pilot bushing failure, and power loss.

The RM-6056 features a 7.05-inch bellhousing depth paired with a universal transmission bore that accepts Ford T5, TKO500/600, TKX, and TR3550 input bearing retainers. It handles up to a 184-tooth flywheel with a 12-inch clutch and works with both Ford OE mechanical fork linkage and hydraulic throwout bearing systems. This is a universal-fit bellhousing, not vehicle-specific, making it the go-to solution for FE swaps and custom builds where factory pieces don't exist.

Note: This bellhousing is NOT SFI 6.1 certified. Many sanctioning bodies require SFI certification for cars running 11.49 or faster in the quarter mile - if that's your application, look for the RM-6056SFI. Founded by former dirt track racer Ross McCombs, QuickTime earned their reputation building bellhousings tough enough for racing abuse. Every RM-6056 is manufactured in the United States.

What's Included

• QuickTime RM-6056 spun steel bellhousing

Overview

Bolting a modern TREMEC 5-speed behind a classic Ford FE big block demands a bellhousing that won't compromise alignment under high-RPM loads. The QuickTime RM-6056SFI delivers SFI 6.1 certification for sanctioned competition while providing the dimensional accuracy that keeps your drivetrain aligned from idle to redline.

What separates QuickTime from conventional steel bellhousings is their exclusive spin-forming process. Rather than rolling or stamping the cone - processes that introduce stress risers and dimensional inconsistencies - QuickTime spins each cone from high-grade steel. This spin-forming process work-hardens the material to over 80,000 PSI tensile strength, delivering more than twice the strength of other steel bellhousings while maintaining the dimensional stability that prevents binding and premature drivetrain wear.

The RM-6056SFI bridges Ford FE engines (352, 360, 390, 427, 428, and 410 Mercury) to Ford-pattern TREMEC transmissions including the T5, TKO-500, TKO-600, TKX, and TR-3550. The dual transmission bore diameter (4.850-inch/4.910-inch) ensures proper fit across these applications. This bellhousing requires a 184-tooth flywheel and accommodates clutch discs up to 12 inches in diameter. Clutch release is your choice - the design accepts mechanical linkage, cable actuation, or hydraulic slave cylinder setups.

QuickTime holds patents on 16 points of bellhousing design and manufacturing process, developed with input from OEMs, engine builders, transmission builders, and racers. When you need the strength for serious horsepower and the precision to protect your investment, this is the bellhousing that delivers. Made 100% in the USA.

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.

What's Included

• Grade 8 steel transmission-to-bellhousing bolts (sized for steel bellhousing applications)
• Hardened steel washers
• Lifetime tech support from MDL

Key Features

• Zero-balance design for internally balanced Ford 390 and 427 FE engines - no counterweights on flywheel required
• 184-tooth hardened ring gear with 15.5-inch diameter for reliable starter engagement
• Cast iron construction delivers OEM-style mass and durability for street and moderate performance use
• 11-1/2 inch clutch bolt pattern accepts standard FE pressure plates
• Six-bolt crankshaft attachment pattern
• NOT compatible with 428ci FE motors (428 requires externally balanced flywheel)

Description

Finding a quality replacement flywheel for your FE-powered Ford shouldn't mean hunting through junkyards or settling for questionable cores. This cast iron flywheel delivers the OEM-spec foundation your 390 or 427 FE drivetrain needs, with the correct zero-balance design that matches how Ford originally engineered these engines.

Ford's 332, 352, 360, 390, 406, and 427 FE engines are all internally balanced - the crankshaft counterweights handle all rotational balance, so the flywheel itself carries no offset weight. This zero-balance flywheel bolts directly to those engines without any machine work or balancing. The cast iron construction provides the rotational mass these big-blocks were designed around, offering smooth engagement and proven durability for street driving and weekend cruising.

The 184-tooth hardened ring gear measures 15.5 inches in diameter, matching the factory specification for proper starter clearance and reliable engagement in any weather. The 11-1/2 inch clutch surface accepts standard Ford FE pressure plates, making this a direct bolt-in replacement for stock or mildly modified applications.

Critical fitment note: This flywheel is designed exclusively for internally balanced 390ci and 427ci FE engines. The 428ci FE is externally balanced and requires a weighted flywheel - see part number MD-LBS-428 for 428 applications. Using this zero-balance flywheel on a 428 will cause vibration issues.

Kit Includes

• Cast iron flywheel with hardened 184-tooth ring gear
• Clutch pattern chart reference guide (PDF)

Key Features

• Billet steel construction delivers superior strength and crack resistance over cast iron at high RPM

• Six-bolt crankshaft mounting configuration
• Precision-machined friction surface resists heat checking
• Made in the USA

Description

Factory cast iron flywheels served their purpose in stock applications, but they become a liability in performance builds. Cast iron is prone to stress cracking under high RPM and increased clutch clamping loads, and at elevated engine speeds, a failing iron flywheel can be catastrophic. This billet steel flywheel solves those problems while retaining the rotational mass needed for confident launches in torque-heavy Ford FE applications.

Billet construction starts with solid steel bar stock that is completely machined to final dimensions. This process eliminates the internal stresses and porosity inherent in castings, resulting in a flywheel that resists cracking and handles higher clamping forces from performance clutches. The material is significantly stronger than gray iron while maintaining the thermal stability needed for repeated heat cycles from aggressive driving.

At 30 pounds, this flywheel strikes the right balance for Ford FE street/strip builds. It is light enough to improve throttle response over a factory cast piece, yet heavy enough to store the rotational energy needed for smooth engagement and strong launches in heavier vehicles. The precision-machined friction surface works effectively with modern organic and ceramic clutch materials.

Designed as a direct bolt-in replacement for internally balanced (zero balance) Ford FE engines including the 390, 427, and 428. The 184-tooth ring gear ensures proper starter engagement, and the 11-inch clutch bolt pattern accepts standard pressure plates. Made in the USA with precision manufacturing standards.

What's Included

• Billet steel flywheel with 184-tooth ring gear
• Precision-machined friction surface
• Zero balance for internally balanced FE engines
• Lifetime technical support from MDL

Key Features

• Billet steel construction eliminates stress cracks and withstands high RPM and heavy clutch clamping loads
• 28oz external balance matches Ford 428ci FE engine requirements
• 184-tooth ring gear for correct FE starter engagement
• 30-pound optimized weight balances rotational inertia with improved throttle response
• 6-bolt asymmetric crankshaft mounting ensures proper counterweight indexing
• 11" clutch bolt pattern compatible with Long style and BBCO pressure plates
• Precision-machined friction surface for consistent clutch engagement
• Made in the USA

Description

Ford's 428ci FE is one of the few FE engines that requires external balance - 28oz of counterweight on the flywheel to offset the longer stroke. Cast iron flywheels handle the job adequately in stock applications, but under performance conditions they become stress-crack liabilities. When you're running aggressive clutch clamping forces and high RPM, you need billet steel.

This Lighten Billet Steel flywheel is machined from solid steel bar stock, delivering the structural integrity that cast iron simply cannot match. The 30-pound weight is deliberately optimized - heavy enough to store adequate rotational energy for smooth launches and drivability, yet light enough to sharpen throttle response compared to stock cast units. The integrated 28oz counterweight is precision-positioned and indexed via Ford's asymmetric 6-bolt crankshaft pattern, ensuring proper balance alignment every time.

The 184-tooth ring gear is correct for Ford FE engines from 1965-on and engages properly with standard FE starters. The 11" friction surface is machined for 11" and 11.5" Long style pressure plate bolt patterns - the same configurations used on factory FE clutch systems. This gives you flexibility to run either traditional Long style three-pair bolt patterns or modern diaphragm-style pressure plates designed for the Long pattern.

Direct bolt-in replacement for Ford 428ci FE engines requiring 28oz external balance. Also fits externally balanced 410ci FE applications. Single-disc clutch compatible. Proudly made in the USA with lifetime technical support from MDL.

Description

When upgrading a Ford big block to a modern TREMEC transmission, the clutch has to bridge two worlds - the original Ford bolt pattern and a 26-spline input shaft that the factory never anticipated. The Big Block Change Over (BBCO) pattern solves this, and MDL's Superior series clutch set delivers the quality and precision that serious builders demand. Hand-assembled in-house at MDL's Caldwell, Idaho facility, every clutch disc is double-checked for accuracy and tolerances before shipping, so you get a ready-to-install premium piece right out of the box.

The organic/organic facing combination offers the ideal balance for street-driven Ford FE, 385-series, and other big block applications. Unlike harsh ceramic or metallic facings that grab aggressively, organic material provides smooth, progressive engagement that's forgiving in stop-and-go traffic while still delivering a solid 400 lb-ft torque capacity. The 11.5-inch long pattern diaphragm pressure plate delivers consistent clamping force across the full disc face with lighter pedal effort than traditional three-finger Long-style pressure plates.

The 26-spline x 1-1/8-inch hub is purpose-built for TREMEC transmission swaps, mating directly to TKX, TKO, and T56 Magnum input shafts. The sprung hub design dampens driveline shock that would otherwise stress synchronizers and input shaft bearings - critical protection when pairing big block torque with a high-performance manual gearbox. This kit is configured for hydraulic release systems (internal or external slave cylinders), so no mechanical throwout bearing is included.

Description

Ford's 385-series big blocks--the 429 and 460--were designed as luxury-car torque monsters, but builders have been putting manual transmissions behind them for decades. The challenge? Finding a clutch that can handle serious torque without requiring a leg press workout at every stoplight. This Superior Series Big Block Change Over clutch kit delivers 650 ft-lbs of torque capacity through an 11.5" long pattern diaphragm pressure plate, giving you the clamping force needed for high-power street and strip duty while keeping pedal effort manageable in hydraulic release setups.

The hybrid friction material strategy is engineered for optimal performance and longevity. Kevlar on the pressure plate side handles initial engagement heat and provides excellent fade resistance under hard use, while the steel-backed organic facing on the flywheel side delivers smooth, progressive engagement for streetable manners. This combination gives you the best of both worlds--aggressive holding power when you need it, civilized behavior when you don't. The profiled clutch fingers ensure even pressure distribution across the entire friction surface.

Every MDL Superior clutch disk is hand-assembled in-house to exacting tolerances. Double-riveted construction ensures the facings stay put under repeated high-load cycles, and each assembly is inspected before it goes in the box. The 26-spline x 1-1/8" sprung hub provides proper damping and matches common Ford performance transmission input shafts. This kit is designed for hydraulic throwout bearing setups--note that the throwout bearing itself is not included.

Compatible with 11.5" long pattern flywheels on Ford big block applications. Made in the USA and backed by MDL's 1-year free-from-defect warranty and lifetime technical support.

Description

When your Ford big block swap needs serious holding power but you're constrained by the 11.5" long pattern bolt circle, the Superior Kevlar/Ceramic clutch kit delivers. The Kevlar/ceramic friction surfaces provide a higher coefficient of friction than standard organic materials, allowing the same clamping force to hold significantly more power--rated at 650 ft-lb of torque capacity. This makes it ideal for high-horsepower street builds, drag racing launches, and road racing where aggressive engagement is critical.

The ceramic face is engineered for racing applications where quick engagement and extreme heat resistance are essential. MDL's ceramic formulation includes iron content that actually increases friction as temperatures rise, making this clutch stronger under punishment rather than weaker. The Kevlar backing provides smooth street manners while the ceramic face delivers race-proven bite.

The 11.5" long pattern diaphragm pressure plate is specifically designed for Ford Big Block Change Over (BBCO) applications. Every Superior clutch disc is hand-built in MDL's Idaho facility to exacting tolerances, then double-checked for accuracy before shipping.

Pressure Plate Bolt Kit | 5/16"-18 x 3/4" | Set of 6

Key Features

• 5/16"-18 thread pitch with 3/4" under-head length
• Complete six-bolt set for standard pressure plate mounting
• Universal fitment for Ford, GM, and Mopar applications using 5/16" hardware
• Critical safety hardware for reliable clutch assembly retention
• Backed by manufacturer's warranty against defects

Description

Pressure plate bolts are among the most critical safety components in any drivetrain. These six fasteners are all that stands between a properly functioning clutch and a catastrophic failure that can destroy transmissions, scatter debris through the bellhousing, or worse. This isn't the place to grab whatever's sitting in the hardware drawer.

This six-bolt kit delivers the 5/16"-18 x 3/4" specification needed for the majority of domestic muscle cars and classic performance applications. The 5/16"-18 thread pitch provides the strength-to-weight balance that made this specification an OEM standard across Ford, GM, and Mopar platforms. The 3/4" under-head length accommodates most standard pressure plate thicknesses without bottoming out in flywheel threads or leaving inadequate engagement.

Unlike generic hardware-store fasteners, these bolts are designed specifically for clutch applications where vibration resistance, proper thread engagement, and precise clamping loads are essential. Proper pressure plate hardware prevents the loosening and shearing that leads to clutch separation under high-RPM loads. Whether you're rebuilding a numbers-matching classic or assembling a street/strip performer, using the correct pressure plate bolts isn't optional.

Compatible with most domestic clutch applications using 5/16" pressure plate bolts. Verify thread specification and length requirements for your specific application before installation.

Description

Every time you stab the throttle, your pressure plate bolts absorb the rotational forces trying to tear your clutch apart. Factory hardware is engineered to a price point - not a performance standard. ARP's High Performance Series pressure plate bolts are forged from premium 8740 chromoly steel and heat-treated to 180,000 PSI tensile strength, delivering a substantial margin of safety over standard Grade 8 fasteners that simply can't match this level of clamping force under stress.

These aren't generic bolts cut to length. Each fastener features a precisely engineered 0.780-inch underhead length optimized specifically for Ford 289-460 V8 applications (1985 and earlier). The large-diameter, low-profile hex head design provides increased shank strength and improved flywheel register engagement compared to OEM hardware. The black oxide finish not only resists corrosion in the harsh bellhousing environment but also looks right on a performance build.

Whether you're building a weekend warrior that sees occasional strip duty or a dedicated road course car that lives at high RPM, these bolts eliminate a critical weak point in your drivetrain. The included hardened washers distribute clamping load evenly across the pressure plate mounting surface, preventing galling and ensuring consistent torque values. For best results, ARP recommends using their Ultra-Torque assembly lubricant to achieve accurate, repeatable torque readings.

Direct fitment for Ford 289, 302, 351W, 351C, 351M, 400, 390, 427, 428, 429, and 460 V8 engines using the standard 5/16-18 six-bolt pressure plate pattern.

Description

Swapping a T5, TKO, TKX, or AOD into your '65-'66 Mustang means your original speedometer cable won't reach or connect properly to the new transmission. This 59" speedometer cable solves that problem, routing from your factory mechanical speedometer head to the speedometer drive on your modern transmission while maintaining accurate speed readings on your original dash.

The cable features the correct 5/8" barrel-style fitting that interfaces directly with the speedometer head used in 1965-1966 Mustangs. At 59" long, it provides proper reach for the routing requirements created by T5, TKO, TKX, and AOD transmission placements in these chassis. The cable also works with original 3-speed manual and automatic transmission configurations, making it a versatile solution whether you're completing a five-speed conversion or simply replacing a worn cable on an automatic-equipped car.

For builders who want to keep the original instrument cluster looking stock while running a modern drivetrain, this mechanical speedometer cable eliminates the need for electronic speedometer conversions or aftermarket gauges. Pair it with the correct driven gear for your tire size and rear axle ratio to dial in accurate speed readings.

What's Included

• 59" speedometer cable with 5/8" barrel connector
• Manufacturer's warranty

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)

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)
