Description

When you need serious torque capacity and crisp shifts in a package that fits classic GM muscle cars without floor surgery, the TREMEC TKX delivers. This all-new 5-speed was designed, tested, and built specifically for the aftermarket - not adapted from OEM production. The result is a transmission purpose-built for Chevelles, GTOs, Cutlasses, Novas, Camaros, and other GM A-bodies with a compact, end-loaded case design that clears most factory transmission tunnels without modifications.

The TCET17805 gear set pairs a 2.87 first gear for strong, manageable launches with a deep 0.68 overdrive that significantly reduces highway RPM for improved fuel economy and reduced engine wear. All gears and shafts are manufactured from ASTM 4615 special grade steel, while the robust internal three-rail shift system with steel shift forks ensures precise engagement through all five gears. Superior shift-ability comes from multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon, allowing confident shifts at engine speeds up to 7,500 RPM.

TREMEC engineers optimized the TKX's three-piece ribbed aluminum housing for structural stiffness while minimizing noise, vibration, and harshness. Tapered roller bearings on the input, output, and counter shafts reduce noise and improve durability, while caged needle bearings support all gear positions to reduce end play. Oversized gear widths increase gear life and torque capacity, and gaskets at all flanges eliminate fluid leaks and simplify installation.

The TKX bolts directly to standard GM Muncie bellhousings, making it a direct replacement for 3-speed and 4-speed Muncie transmissions. The 26-spline input shaft requires a matching clutch disc, while the 31-spline output shaft provides increased strength for high-torque applications. Includes a high-performance short-throw billet aluminum shifter that isolates road noise while delivering clean, crisp shifts. Like all TREMEC aftermarket transmissions, the TKX is made from 100% brand-new OEM-quality components. When purchased as part of an MDL complete conversion package, you receive an extended manufacturer warranty plus lifetime technical support.

Description

When your classic GM muscle car is making north of 400 horsepower and that antiquated 4-speed is holding you back, the TREMEC TKX delivers the overdrive upgrade you need. Unlike transmissions repurposed from OEM applications, the TKX was designed, tested, and built from the ground up specifically for the aftermarket. The result is a purpose-built 5-speed that combines universal packaging with the durability and shift quality that high-horsepower restomods demand.

The engineering focus shows in every component. All gears and shafts are machined from special-grade ASTM 4615 steel for increased torque-carrying capacity. Sintered carbon/bronze hybrid triple-cone synchronizers deliver smooth, precise shifts even at 7,500 RPM. The gear layout is optimized to minimize noise, vibration, and harshness while oversized gear widths and caged needle bearings in all gear positions maximize durability. A ribbed three-piece aluminum housing provides outstanding structural stiffness while keeping weight down to just 99 lbs dry.

The compact end-loaded case design clears most GM A-body transmission tunnels without cutting - Chevelle, GTO, Cutlass, Nova, and Camaro applications typically bolt right in. Three shifter positions offer flexibility for factory console alignment, and the low-profile shifter plate keeps everything tight. This close-ratio 2.87:1 first gear with 0.81:1 overdrive fifth provides strong acceleration while dropping highway RPM for comfortable cruising and improved fuel efficiency.

Bolts directly to existing GM Muncie bellhousings or Quicktime SFI-approved bellhousings. The GM-pattern input features a 0.590 in. pilot tip and 1.375 in. OD throwout bearing guide tube. Gaskets at all mating surfaces eliminate fluid leaks and simplify installation. MDL backs every transmission with an extended warranty and lifetime technical support.

Description

When your four-speed can't keep up with modern horsepower levels and you need a five-speed that actually fits, the TREMEC TKX delivers. This transmission was designed from the ground up specifically for the aftermarket - not adapted from an OE application - with classic muscle car tunnels in mind. The end-loaded case design provides superior tunnel clearance without the floor cutting that other swaps require, making it a true drop-in solution for GM A-bodies like the Chevelle, GTO, Cutlass, Nova, and Camaro.

This wide-ratio version pairs a deep 3.27 first gear for aggressive launches with a 0.72 overdrive fifth that drops highway RPM significantly - the ideal combination for street performance builds where you want strong acceleration off the line without sacrificing cruising comfort. All gears and shafts are machined from special grade steel (ASTM 4615) for increased torque carrying capacity, and tapered roller bearings on the input, output, and countershafts reduce noise while improving durability. The hybrid triple cone synchronizers - combining sintered carbon and bronze materials with a non-leading tooth profile - deliver smooth, positive shifts even at high RPM.

The TKX bolts directly to GM 3-speed and 4-speed Muncie/Richmond bellhousings, using the same mounting points as your factory transmission. The 26-spline input shaft accepts GM-pattern clutch discs, while the beefy 31-spline output shaft handles the transmission's full 600 lb-ft rating. A 0.590-inch pilot tip and 1.375-inch OD throwout bearing guide tube maintain GM compatibility throughout the drivetrain.

Every TKX ships with the high-performance short-throw billet aluminum shifter, reverse light switch (left side), and cruise control safety switch provision (right side). Recommended fluid is Dexron III ATF, Amsoil ATF, TREMEC HP-MTF, or Mobil 1 Synthetic ATF - capacity is 2.7 quarts.

Description

Getting a TKX shifter in the factory position on a '67 Camaro or Firebird means dealing with offset challenges the stock TREMEC shifter wasn't designed to solve. The MDL Qwik Stik is purpose-built for this application: a short-throw, close-ratio shifter with a 1" left offset and your choice of .65" or 1.15" forward stub placement to land the lever exactly where the factory console expects it.

The precision-machined billet aluminum construction eliminates the flex and vagueness of stamped steel designs while saving weight. Belleville washers create positive detent engagement that translates to lightning-fast, confidence-inspiring shifts—particularly noticeable in the 2-3 gate where sloppy shifters cost time. The compact top turret sits lower than stock, clearing tight F-body tunnel openings without floor modifications.

Unlike designs with internal stops that can break or wear, the Qwik Stik relies on the TKX's internal three-rail shift system for gear engagement, making service access simple when needed. The 7/8" on-center shift stub works with most aftermarket levers, so you can run your preferred setup. A high-temperature dust boot seals the assembly against oil and road debris.

Direct bolt-on installation to the TKX transmission with included mounting hardware. Designed, machined, and assembled in the USA with lifetime technical support available at 208-453-9800.

Description

When your build demands serious protection without compromise, the QuickTime RM-6022 bellhousing delivers SFI 6.1 certified scattershield strength between your small block or big block Chevy and GM-pattern manual transmissions. Factory bellhousings and stamped aftermarket alternatives flex under power, causing accelerated drivetrain wear and misalignment through the RPM range. QuickTime's proprietary spin-forming process eliminates that weakness entirely.

Unlike rolled or stamped steel bellhousings, QuickTime's spun cone work-hardens during manufacturing to over 80,000 PSI - delivering twice the strength of conventional steel designs while maintaining dimensional accuracy that keeps your engine and transmission in perfect alignment. This pinpoint precision protects clutches, input shafts, and pilot bearings from the flex-induced wear that destroys drivetrains. The process incorporates 16 patented design points that make this the most dimensionally stable bellhousing on the market.

The RM-6022 bridges Chevrolet small block and big block V8 engines (including 1992-96 LT1) to transmissions using the GM standard bolt pattern: Muncie, Saginaw, Richmond, Borg Warner T10, Jerico, Falcon, Bert, Brinn, and TREMEC TKO/TKX. The 9:00 clutch fork opening provides correct geometry for GM-style mechanical linkage, while the design also accepts hydraulic throwout bearings for modern clutch actuation. A 4.685-inch transmission bore diameter centers GM-pattern transmissions precisely.

This is a universal-fit bellhousing engineered for engine-to-transmission adaptation, not vehicle-specific applications.

Install Hardware Kit | Chevy SBC/BBC to TKX | Aluminum Bellhousing

Key Features

• Bolt lengths specifically selected for aluminum bellhousing applications - prevents thread damage from over-length fasteners
• Complete bellhousing-to-transmission hardware for TREMEC TKX installations on Chevy Small Block and Big Block engines
• Eliminates parts-counter guesswork when sourcing individual fasteners
• Professional-grade hardware engineered for high-torque drivetrain applications

Description

Aluminum bellhousings demand precise fastener selection. Run a bolt that's even slightly too long and you risk bottoming out in blind threaded holes, stripping threads, or failing to achieve proper clamping force between the bellhousing and transmission. This hardware kit takes the guesswork out of your Chevy SBC or BBC to TREMEC TKX conversion by providing bolts engineered specifically for aluminum bellhousing applications.

The critical difference between aluminum and steel bellhousing hardware kits comes down to bolt length. Aluminum castings often feature shallower thread engagement depths than their steel counterparts, requiring shorter fasteners to avoid damage. In some cases, certain bolts are eliminated entirely where the bellhousing manufacturer has already provided integrated hardware. This kit accounts for those differences, giving you exactly what you need for a clean, damage-free installation.

Whether you're dropping a TKX behind a classic small block in a Chevelle, Nova, or Camaro, or pairing one with a big block build, this kit ensures you have the correct mounting hardware from day one. Stop wasting time at the parts counter and get back to wrenching.

What's Included

• Bellhousing-to-transmission mounting bolts sized for aluminum bellhousing applications
• All necessary hardware for TREMEC TKX installation

Key Features

• Steel bellhousing-specific hardware kit -- correct bolt lengths for thicker Lakewood and QuickTime steel housings
• Grade 8 fasteners for high-torque, high-vibration drivetrain applications
• Hardened washers distribute clamping loads evenly across mounting surfaces
• Eliminates hardware store guesswork -- one kit, all the fasteners you need
• Torque specification: 35 ft-lbs for transmission-to-bellhousing bolts

Description

Steel bellhousings require different hardware than their aluminum counterparts. The thicker steel construction of Lakewood and QuickTime scatter shields demands specific bolt lengths that you won't find at the local hardware store -- and using the wrong fasteners means either insufficient thread engagement or bolts that bottom out before clamping. This hardware kit solves that problem with precision-selected Grade 8 bolts sized specifically for steel bellhousing applications.

The kit includes everything needed to secure your TREMEC TKX transmission to a GM-pattern steel bellhousing on small block or big block Chevy applications. Grade 8 fasteners deliver the strength required for high-torque drivetrains, while the included hardened washers prevent fastener galling and distribute clamping loads evenly across the mounting flange. Torque all transmission-to-bellhousing bolts to 35 ft-lbs for proper retention.

The GM TKX uses the same Muncie/Richmond 4-speed bolt pattern that's been standard on GM manual transmissions for decades, making bellhousing selection straightforward. This kit pairs with steel bellhousings designed for that pattern -- the thicker steel construction provides added safety in high-horsepower applications where an SFI-rated scatter shield is required or preferred.

What's Included

• Grade 8 transmission-to-bellhousing bolts (steel bellhousing length)
• Hardened steel washers

Key Features

• Nodular (ductile) iron construction delivers superior tensile strength, impact resistance, and crack resistance over gray cast iron
• 168-tooth ring gear with 14.086" diameter for compatibility with angle bolt pattern starters
• Zero balance for internally balanced Chevy small block and big block engines
• 12-5/8" pressure plate bolt pattern accepts 11" clutch discs
• 2.485" crankshaft register bore sized for two-piece rear main seal engines
• 6-bolt crankshaft mounting with 7/16" bolt pattern
• 30 lb. weight provides smooth engagement and adequate rotational mass
• Direct bolt-in replacement--no resurfacing of a worn core required

Description

Whether you're converting to a manual transmission or replacing a worn or damaged flywheel, this nodular iron unit delivers a cost-effective upgrade over gray cast iron without the expense of billet steel. Nodular iron--also known as ductile iron--transforms gray iron's crack-promoting graphite flakes into spheres through a specialized alloying process. The result is a material with superior yield strength, elongation, and impact resistance compared to conventional cast iron, making it an excellent choice for high-performance street engines.

This flywheel fits '55-'85 Chevy small block and big block V8s equipped with two-piece rear main seals. The 2.485" crankshaft register bore ensures proper centering on compatible cranks, while six 7/16" bolts secure the flywheel to the crankshaft flange. The precision-machined clutch surface provides consistent engagement, and the zero balance specification makes this flywheel compatible with all internally balanced engines from this era--265, 283, 302, 305, 327, 350, 396, 427, and 454 applications included.

The 168-tooth ring gear measures 14.086" in diameter and requires an angle bolt pattern starter. Transmission bellhousings will clear both 153-tooth and 168-tooth flywheels, but starter selection is critical--verify your block is drilled for the angle bolt pattern or plan to add the holes. The 12-5/8" pressure plate bolt pattern accepts 11" clutch discs, giving you access to higher-capacity clutch options compared to the smaller 153-tooth flywheels limited to 10.5" discs.

At 30 lbs., this flywheel provides adequate rotational mass for smooth idle and engagement characteristics on street-driven vehicles. Nodular iron is an ideal balance between the brittleness of gray iron and the cost of SFI-rated billet steel--well suited for spirited street use below 6,000 RPM. For dedicated racing applications or engines running sustained high RPM, step up to a billet steel SFI-rated unit.

Description

When GM introduced the one-piece rear main seal on 1991-and-later 454 big-block engines, the flywheel mounting dimensions changed significantly from the earlier two-piece seal design. This lightened billet steel flywheel is purpose-built for Gen V and Gen VI 454 engines, featuring the correct 2.485-inch center register bore and updated bolt circle that one-piece rear main seal cranks require. If your block rolled off the line in 1991 or later, this is the flywheel that fits.

At 25 pounds, this billet steel unit cuts significant rotational mass compared to heavy OEM cast iron flywheels while retaining the durability and heat capacity that street-driven big-blocks demand. The external balance design incorporates the precise counterweight distribution required by 454 rotating assemblies, which cannot achieve internal balance due to stroke length and counterweight packaging constraints inside the crankcase.

The 168-tooth ring gear ensures proper engagement with angle-bolt-pattern starters standard on big-block Chevy applications. The 12-5/8-inch clutch bolt pattern is sized for 11-inch pressure plates, making this flywheel ideal for street performance builds where improved throttle response and quicker revs matter without sacrificing smooth launches and daily drivability.

This flywheel will not fit earlier 1970-1990 Mark IV 454 engines with two-piece rear main seals--those applications require a different flywheel with different mounting dimensions. Precision-machined and made in the USA, this flywheel delivers the quality and fitment accuracy your 454 manual transmission conversion or rebuild demands.

What's Included

• One lightened billet steel flywheel with 168-tooth ring gear
• External balance counterweighting for 1991-up 454 applications
• Precision-machined friction surface

• Zero (internal) balance configuration for Chevy 265-427 and 572 engines
• 2.485" crankshaft register diameter fits 2-piece rear main seal applications
• Dual clutch bolt pattern accepts both 10.5" (11-5/8" bolt circle) and 11" (12-5/8" bolt circle) clutch assemblies
• Six-bolt crankshaft mounting pattern
• 25 lb. weight balances performance gains with street drivability
• Made in the USA

Product Overview

Reducing flywheel weight is one of the most effective ways to improve throttle response and free up horsepower that would otherwise be lost spinning excess rotating mass. This lightened billet steel flywheel strips weight strategically while retaining the structural integrity and heat dissipation characteristics that billet steel provides. The result is quicker revs, sharper acceleration, and a more responsive drivetrain without the harsh engagement or stalling tendencies of ultra-lightweight aluminum units.

This flywheel is engineered for internally balanced (zero balance) Chevy small block and big block engines with 2-piece rear main seals. That covers the classic 265, 283, 302, 305, 307, 327, 350, 396, 402, and 427 cubic inch displacements, plus the 572 crate engine. The 2.485" crankshaft register diameter and six-bolt flange pattern ensure proper centering and secure mounting on these applications. Keep in mind that 400 small blocks and 454 big blocks use external balance cranks and require a different flywheel.

The dual clutch bolt pattern gives you flexibility in clutch selection, accepting both GM 10.5" clutches with the 11-5/8" bolt circle and 11" clutches with the 12-5/8" bolt circle. At 25 pounds, this flywheel sits in the sweet spot between full-weight OEM units and aggressive race-only aluminum flywheels, delivering noticeable performance improvement while maintaining smooth engagement and everyday drivability. The 168-tooth ring gear works with standard Chevy starters and fits most aftermarket bellhousings.

Description

When you need better strength than brittle cast gray iron but don't require the cost of billet steel, nodular iron delivers the ideal middle ground. This flywheel replaces factory and gray iron units with superior nodular iron construction that transforms the crack-promoting graphite flakes found in conventional castings into spheres or nodules - giving the metal enhanced ductility, yield strength, and impact resistance.

At 30 pounds, this flywheel maintains the standard weight range that V8 street engines need for smooth operation. Heavier flywheels store more rotational energy to help get your vehicle moving smoothly from stops and reduce the abrupt engagement characteristics that lightweight flywheels can exhibit in traffic. The 168-tooth ring gear requires an angle-mount starter and fits large GM bellhousings - if you're switching from a 153-tooth flywheel, confirm your starter bolt pattern matches.

Designed specifically for 1986-up Gen II small block Chevy engines with one-piece rear main seals, this flywheel features the smaller 3.00-inch crankshaft bolt circle and 2.067-inch register bore that distinguish one-piece seal engines from earlier two-piece designs. The 23oz external imbalance is factory-correct for stock 305/5.0L and 350/5.7L rotating assemblies - note that this flywheel does not fit 383 stroker combinations, which typically require a neutral-balance or differently-weighted flywheel depending on crankshaft selection.

The 12-5/8-inch pressure plate bolt pattern accepts standard 11-inch single disk clutches. For motorsports applications, understand that while nodular iron offers significant improvements over gray iron, billet steel remains the preferred choice for sustained high-rpm use above 6,000 rpm or high-horsepower drag racing with sticky tires.

Description

High-output GM builds often face a clutch dilemma: maximum holding power is required, but engine bay constraints prevent stepping up to a larger diameter disc. The Superior 11" Kevlar/Ceramic clutch set solves this problem by combining aggressive friction materials with a low lever height design specifically engineered for hydraulic concentric slave cylinder applications. The result is 600 lb-ft of torque capacity in a package that clears modern hydraulic release systems without binding or inconsistent pedal feel.

The dual-compound friction disc places Kevlar on the pressure plate side and ceramic on the flywheel side--a combination that delivers the best of both materials. Ceramic's higher coefficient of friction provides the hard-hitting bite needed for drag launches and quick shifts, while Kevlar contributes smoother engagement characteristics. The ceramic material contains iron particles that actually increase friction as temperatures rise, making this clutch thrive under sustained abuse in road course and strip conditions where lesser friction materials would fade.

Every Superior clutch disc is hand-assembled in MDL's facility to exacting tolerances. Double-riveted construction ensures the friction material stays put under repeated high-load cycles, while the sprung hub design absorbs driveline shock and smooths power delivery. The diaphragm-style pressure plate provides consistent clamping force across the entire disc surface. This clutch set fits GM bellhousing patterns with a 12-5/8" equalizer bolt pattern and mates to any 26-spline, 1-1/8" input shaft--including TREMEC TKX, TKO, and T56 Magnum transmissions.

Description

When you have pushed past 1,000 horsepower and still need to drive to the track, run hard, and drive home, the McLeod RXT 1200 delivers the holding power without the leg cramps. This twin-disc clutch handles up to 1,200 crank horsepower while maintaining a comfortable pedal feel that will not leave you massaging a charlie horse after a trip through downtown at rush hour.

The RXT 1200 features ceramic-lined clutch discs that provide slightly aggressive engagement with soft pedal effort. The higher clamp load compared to the standard RXT gives you the grip needed for serious power while the twin-disc design keeps rotating mass low for quick revs. The Blanchard-ground floater plate with multiple straps minimizes driveline noise - you may hear some feedback tones between 1200-1900 RPM, which is normal for twin-disc applications.

McLeod's patent-pending large red adapter ring system eliminates the need for a dedicated flywheel. The ring mounts to your existing large-diameter flat-style flywheel (Chevy 168T and similar) and provides the proper mounting surface for the twin-disc assembly. This adapter ring approach reduces cost while maintaining strength.

Description

When your small block or big block Chevy build demands serious torque capacity without sacrificing street manners, the Tilton ST-246 twin-disc clutch delivers. Rated at 850 lb-ft with its sprung-hub organic discs, this assembly provides the holding power of a race clutch with engagement smooth enough for daily driving. The sprung center hub dampens engine vibrations and reduces gearbox noise—critical for street applications where you want performance without the harshness of a solid-hub setup.

Unlike many performance clutches that bolt a floater plate onto an OEM-type stamped steel pressure plate, the ST-246 was engineered from the ground up as a true twin-disc clutch. The precision-machined aluminum clutch cover shares technology directly from Tilton's championship-winning OT-Series racing clutches, delivering superior strength, stiffness, and dynamic balance compared to stamped steel alternatives. The high-mass main pressure plate and floater plate—machined from the same proprietary materials used in Tilton's racing clutches—provide exceptional heat capacity and resist warpage under hard use. The floater plate runs twice the thickness of most competing twin-disc designs, which eliminates gear clatter and dramatically improves heat dissipation.

The billet chromoly steel flywheel features a precision register that locates the clutch for optimal balance of the entire assembly—a significant improvement over the loose-fitting bolts and dowels typical of stamped steel clutch setups. The integrated 153-tooth chromoly ring gear matches early Chevy starters and eliminates the failure point of separate ring gear assemblies. Internal balance configuration suits traditional small block and big block Chevy engines.

This kit fits TREMEC T56 Magnum and TKO transmissions with 26-spline, 1-1/8-inch input shafts. Compatible with OEM release bearings for straightforward installation. Since 1972, Tilton Engineering has supplied small-diameter racing clutches to championships in F1, NASCAR, IMSA, IndyCar, SCCA, Formula Drift, and SCORE—the ST-246 brings that same engineering to high-performance street applications.

Description

Hydraulic clutch systems demand leak-free, pressure-resistant fluid lines that won't degrade over time or expand under load. This 24-inch stainless steel braided line delivers the durability and consistent pedal feel that separates a professional hydraulic clutch installation from a compromise. The PTFE (Teflon) inner lining provides excellent chemical compatibility with all common hydraulic fluids while resisting the swelling and deterioration that plague standard rubber lines.

The stainless steel braided construction prevents expansion under pressure, maintaining a firm, responsive clutch pedal. Unlike rubber hoses that can balloon and soften pedal feel, stainless braided PTFE lines keep the inner diameter uniform for efficient fluid transfer. The clear plastic outer coating shields the braid from abrasion, contamination, and corrosion while letting you visually inspect line condition at a glance.

At 24 inches with a 1/4-inch I.D., this line is sized specifically for hydraulic clutch applications. It's an excellent choice when pairing a Tilton 6000 HRB with an -4AN male union to a firewall-mounted or bulkhead-mounted master cylinder. The straight -4AN female fittings on both ends connect directly to standard -4AN male adapters without additional fittings, reducing potential leak points and simplifying installation.

Every line is pressure tested before leaving the facility to verify seal integrity. Premium stainless steel crimp sleeves and fittings ensure a permanent, vibration-resistant connection. Proudly manufactured in the United States.

Whether you're finishing a concours-quality restoration or building a street machine that gets driven hard, this shift ball combines authentic styling with materials engineered to handle real-world abuse.

The 5-speed pattern graphics are subsurface-engraved into the black polymer resin, meaning they cannot wear off no matter how many miles you log. Unlike painted or printed shift knobs that fade and flake over time, this pattern stays crisp for the life of the knob. The high-impact polymer resin is specifically formulated to meet performance-level torque and temperature requirements without developing stress cracks as it ages.

Underneath the show-quality exterior, a brass master insert provides the structural backbone. This insert exceeds automotive industry specifications of 200 lb/ft static pull and 20 lb/ft twist torque, giving you the confidence to bang through gears without worrying about thread failure.

Description

Worn shift balls with faded graphics look cheap and undermine an otherwise clean build. This MDL 5-Speed Black Shift Ball solves that problem with subsurface graphics that are embedded below the polished surface - they physically cannot wear off, fade, or chip regardless of how many miles you put on the car or how aggressively you shift.

The ball is constructed from a specially formulated high-impact polymer resin developed specifically for automotive applications. Unlike generic plastics that crack and degrade with age and temperature cycling, this formulation resists stress cracking even after years of exposure to heat, cold, and UV light. At 4 ounces, the weight is calibrated to provide positive shift engagement without the excessive mass that can stress synchronizers or create unwanted momentum during quick shifts.

Inside, a brass or aluminum master insert provides the threaded mounting point and exceeds automotive industry specifications - tested to withstand 200 ft. lbs. of static pull force and 20 ft. lbs. of twist torque. The 3/8"-16 internal threading fits most domestic shifter applications, and MDL stocks thread adapters for virtually any shifter setup if your lever uses a different thread pitch. Each ball is precision machined and polished to a high-gloss finish that looks as good as it feels.

Made in the USA by a manufacturer that has been producing precision shift components since 1952, this shift ball delivers the quality and attention to detail that serious builds demand. Whether you are finishing a classic muscle car, a restomod, or a modern performance machine, the MDL logo and 5-speed pattern tell everyone you built it right.

• Polished high-gloss finish for durability and professional appearance
• Made in the USA

Description

The shift knob is your primary connection point to the drivetrain during every gear change. This white 5-speed shift ball delivers the durability and feel you need with high-impact polymer resin specifically formulated for automotive applications. Unlike generic plastics that develop stress cracks over time from temperature cycling and repeated use, this material is engineered to handle real-world performance conditions.

The 1-7/8" diameter provides excellent grip surface and comfortable palm contact. The 5-speed shift pattern is applied subsurface, meaning the graphics are embedded within the material rather than printed on top -- they physically cannot wear off from years of shifting. The entire ball is precision machined and polished to a high-gloss finish that resists scratching and cleans easily.

At the core is a brass master insert machined to 16mm x 1.50 threading. This insert is tested to exceed automotive industry specifications: 200 ft-lbs of static pull and 20 ft-lbs of twist torque. Because the knob uses the common 16mm x 1.50 master insert, it accepts MDL's complete line of thread reducing inserts -- so you can adapt it to fit 3/8"-16, 3/8"-24, 5/16"-18, 12mm x 1.75, 10mm x 1.50, and other common shift lever thread sizes. If your shifter doesn't use 16mm x 1.50 threading, just add the appropriate reducer to make it work.

Weighing 4 ounces, this knob provides enough mass for positive shifting feedback without the excessive weight that can stress shift mechanisms or cause gear selection issues. Made in the USA with automotive-grade materials and quality craftsmanship.

• Includes wiring for various reverse lockout applications
• Compatible with thread reducers for adapting to other shifter thread sizes
• Made in the USA

Description

Slamming into reverse at speed is a quick way to grenade a gearbox. This 5-speed shift ball eliminates that risk with an integrated side-mounted push button lockout that requires deliberate activation before reverse can be selected. The button includes wiring for connection to various shifter configurations that utilize electronic or mechanical reverse lockout functionality.

The ball itself is built from specially formulated high-impact polymer resin designed specifically for the automotive industry. Unlike cheap plastic knobs that crack under stress or go chalky from heat cycles, this material resists stress cracking with age while handling the torque and temperature swings of hard driving. The 1-7/8" diameter provides solid palm contact for confident shifting, and the polished white finish cleans up easily.

Mounting uses a 16mm x 1.50 brass master insert with an included brass jam nut. This thread size is common on 1982-2002 Camaro and Firebird shifters, Pontiac Fiero applications, and various aftermarket shifters. For other thread sizes, pair this shift ball with MDL thread reducers to adapt down to your specific shifter requirements.

Made in the USA from a manufacturer that has been producing quality shift knobs for decades.

This 5-speed black shift ball puts a side-mounted momentary push button exactly where your thumb naturally rests, giving you instant access to nitrous activation, line lock, or other electrical accessories without fumbling for a dashboard switch or console button.

The side-mount placement is intentional: unlike top-mounted buttons that can be accidentally triggered during aggressive shifts, this configuration requires deliberate engagement. The included 18" wire harness gives you plenty of length to route to your relay or control module, with terminals ready for connection. Whether you're staging at the strip or wiring in a secondary system, the button is right there when you need it.

Built from black polymer resin, this 2-1/8" diameter shift ball delivers comfortable ergonomics for extended driving sessions while standing up to the abuse of street and track duty. The 16mm x 1.5 threads are the industry-standard size for shift knob adapters, which means you can pair this ball with MDL's thread reducing inserts to fit virtually any shift lever thread pitch -- from 3/8"-16 to 5/16"-18 and beyond.

Description

Upgrading to a Lokar shift lever on your TREMEC-equipped build but don't want to give up your favorite shift knob? This thread reducing insert solves the compatibility problem. Lokar shifters use 3/8-24 threads at the top of the lever, while many OEM and aftermarket shift knobs--including popular universal 16mm-threaded styles--won't thread directly onto that pattern. This insert bridges the gap, letting you mate a 16mm-threaded knob to your new Lokar lever.

The insert threads into the internal 16mm threads of your shift knob, presenting external 3/8-24 threads that mate directly to the Lokar lever. The included jam nut cinches down against the lever to lock the assembly in place, preventing the knob from backing off during spirited driving or repeated shifting. It's a small piece of hardware that makes a big difference when you're mixing and matching components to get exactly the look and feel you want in your build.

This reducer is a common solution for classic Jeep CJ5, CJ6, CJ7, and CJ8 later models, as well as 1936-1946 and 1967-1972 Chevy truck builds where Lokar shifters are installed on TREMEC T5, T45, T56, TKO, or TKX transmissions. If you've got a knob you love and a Lokar lever on the way, this is the adapter you need.

Description

TREMEC T-56 Magnum, TKX, TKO, and T5 transmissions use a Ford-based mechanical speedometer drive, which creates a problem when you're running a GM chassis with a 7/8" threaded speedometer cable. Without an adapter, you're stuck either fabricating a custom cable or dealing with a leak-prone import solution that fails at the worst possible time.

This precision-machined adapter is engineered to eliminate the chronic leakage issues that plague cheaper alternatives. The double O-ring seal system addresses leaks at the transmission case opening, while a dedicated internal seal prevents fluid from wicking up through the cable attachment point—a common failure mode on single-seal designs. The Swiss steel drive spindle provides extra strength and accuracy for consistent speedometer readings over the life of the build.

The billet housing paired with a naval brass bushing ensures smooth cable rotation and extended service life, even in high-vibration environments. The one-piece construction eliminates the potential leak paths and wear points found in multi-piece adapter assemblies.

Fits Ford T5, all 3550/TKO models, TKX, Ford T56 with cable drive, all TREMEC Magnum six-speeds, and Ford three- and four-speed transmissions. Made in the USA with full warranty coverage.

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.

Kit Includes

• 17-tooth speedometer driven gear, white plastic

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

• 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

• 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

• 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

Description

Big block swaps shift the drivetrain's centerline compared to small block installations, and that changes everything about crossmember fitment. When you're dropping a TREMEC TKX or TKO 5-speed behind a big block in your first-gen F-body or X-body, the factory crossmember won't work -- and neither will small block crossmembers. This Bowler tubular crossmember solves that problem with a design specifically engineered for big block positioning.

The slim tubular construction addresses one of the most common fitment headaches on these builds: exhaust clearance. Where bulkier OEM-style crossmembers force compromises with header selection or pipe routing, Bowler's design allows proper dual exhaust clearance while maintaining correct transmission mount positioning. The black powder coat finish provides durable corrosion protection that holds up under heat and road grime.

Installation is straightforward, using your car's original crossmember mounting points in the chassis -- no drilling or fabrication required. The crossmember works with both stock-height and 1/2-height body bushings, so it accommodates lowered cars without modification. Note that compatibility with aftermarket subframes depends on whether the vendor maintained OEM crossmember mounting locations; some aftermarket subframes relocate these points.

This crossmember fits 1967-1969 Camaro and Firebird F-bodies, plus 1968-1972 Nova X-bodies. It supports TKX, TKO-500, and TKO-600 transmissions when paired with big block engines. If you're running a small block, you'll need a different crossmember designed for that engine's positioning.

What's Included

• Bowler tubular steel crossmember with black powder coat finish

The smooth outer journal ensures uniform contact with the transmission seal, preventing leaks while promoting proper slip action during suspension travel. This attention to detail eliminates the fluid weeping common with lesser yokes.

This 31-spline configuration directly fits TREMEC TKX, TKO-500, TKO-600, and T56 Magnum transmissions, as well as Ford C6 and FMX automatics, Ford Toploader 4-speeds, and ZF 5-speed transmissions. Whether you're building a restomod, pro-touring car, or weekend warrior, this Sonnax slip yoke delivers the strength and durability your drivetrain demands.
