Description

When TREMEC set out to replace the legendary T56, they didn't just update it - they engineered the Magnum from the ground up using TR-6060 architecture found in factory supercars like the C6 ZR1 Corvette and Viper ACR. The result is the strongest, smoothest-shifting 6-speed manual transmission available for the aftermarket, purpose-built for GM LS engines as well as big-block and small-block applications when paired with the correct bellhousing.

This close ratio version (TUET11009) features gear ratios optimized for high-performance street driving and road racing. The 2.66 first gear launches hard without being too aggressive, while the tightly-spaced 1.78 second, 1.30 third, and 1:1 fourth keep you in the meat of your powerband. The double overdrive - 0.80 fifth and 0.63 sixth - drops highway RPM dramatically, improving both cruising comfort and fuel economy. The 4616 chromoly gears feature two-piece laser-beam welded construction with increased face widths for greater strength and more precise tooth geometry.

Inside, the Magnum benefits from modern OEM synchronizer technology: triple cone units on gears 1-4 and double cone on 5-6 and reverse deliver incredibly short, low-effort shift throws with precise engagement even at high RPM. The redesigned shift forks eliminate the wear issues that plagued earlier T56 designs, and the extensively modified case prevents leaks under high-stress conditions. The fully reversible TKO-style aluminum shifter provides multiple mounting positions, and built-in mid-shift provisions under the inspection cover make forward shifter relocation simple for bench-seat classics.

Compatible with GM big-block, small-block, and LS engines using the appropriate bellhousing. Uses standard T56 bellhousing bolt pattern with internal CSC (concentric slave cylinder) mounting provisions. Requires Dexron III ATF. Rated to 7,800 RPM.

Description

The TREMEC T-56 Magnum eliminates the compromise between strength and driveability that plagued earlier 6-speed conversions. Introduced in 2009 as the long-awaited replacement for the original T-56, the Magnum combined the best of TREMEC's OEM TR-6060 design with the most popular features of their TKO 5-speed. Known in OEM form as the TR-6060, this is the same transmission architecture found in factory supercars including the Dodge Challenger and Viper, and the Chevrolet Camaro - now available for your GM-powered build.

The TUET16885 wide-ratio gear set delivers a 2.97:1 first gear for aggressive launches paired with closely-spaced 5th (0.80:1) and 6th (0.63:1) overdrives for comfortable highway cruising at lower RPMs. This ratio spread makes the wide-ratio Magnum ideal for street machines, restomods, and pro-tourers where you want strong off-the-line acceleration without screaming RPMs at 70 mph.

Engineering improvements over the original T-56 are substantial. Gear face widths have been significantly increased, and 2-piece laser-beam welded gear construction allows greater control of tooth angles, pitch, and alignment. The bolstered one-piece countershaft resists distortion, while redesigned shift forks with permanently mounted shift links eliminate the wear and float that caused incomplete shifts in earlier designs. Spring-loaded ball-type inserts replace the stamped-steel shift keys of previous generations, delivering short, smooth shifts without the notchy feel.

The Magnum works with GM small block, big block, and LS engines when paired with the correct bellhousing. Clutch release provisions are modeled after the T-56 in 1998-2002 Camaros and Firebirds, designed for use with hydraulic throwout bearings. Multiple shift stub relocation kits are available for use with factory 4-speed consoles. When you purchase from MDL, you get our extended warranty coverage plus lifetime technical support from drivetrain experts who actually use these parts.

Description

The original T56 topped out around 450 lb-ft - fine for stock applications, but a liability once you started adding power. The TREMEC T56 Magnum solves that problem decisively, delivering 700 lb-ft of torque capacity in a purpose-built aftermarket package based on the TR-6060 architecture found in factory supercars like the Corvette ZR1 and Dodge Viper ACR.

This wide-ratio version (TUET11012) features a 2.97 first gear for aggressive launches and street-light acceleration, while the double overdrive - 0.74 in fifth and 0.50 in sixth - drops highway RPM significantly for better fuel economy and reduced engine wear. TREMEC widened the gear faces substantially over the original T56, then added 2-piece laser-beam welded construction for precise control of tooth angles, pitch, and alignment. Triple-cone synchronizers on gears 1-4 and double-cone on 5-6 deliver smooth, high-rpm shifts without grinding or balking - even when you're banging through the gears hard.

The reversible die-cast aluminum shifter eliminates the limitations of earlier cast-iron designs, providing TKX-style precision with short, low-effort throws. Dual speedometer pickups handle both mechanical cable-driven and electronic setups without adapters. Built-in provisions for mid-shift conversions sit under the inspection cover, ready when your application demands a different shifter location. The T56-style bellhousing bolt pattern makes installation with various late-model GM engines straightforward.

At 34.85 inches overall length, tunnel modification is required for most classic muscle car conversions - this is not a drop-in for '98-'02 F-bodies or '04-'06 GTOs. The 26-spline input matches LS-series engines directly, while the 31-spline output handles serious driveline torque. When you purchase through MDL, you get the standard TREMEC warranty plus an additional year of coverage, along with lifetime technical support to help you get your conversion dialed in right.

Description

Sourcing the correct hardware for a T56 Magnum installation can derail an otherwise straightforward build. Different bolt lengths, thread pitches, and grades are required at various mounting points throughout the bellhousing assembly, and mixing up specifications leads to stripped threads, improper clamping force, or worse. This hardware kit eliminates the guesswork by providing every fastener needed to properly mount your steel bellhousing to an LS engine block and bolt the T56 Magnum transmission to the bellhousing.

The kit includes eight 10mm-1.5 x 50mm hex flange bolts with black finish for the primary bellhousing-to-engine connection, along with eight 10mm-1.5 x 40mm black hex flange bolts for transmission-to-bellhousing mounting. Two shorter 10mm-1.5 x 30mm hex flange bolts handle secondary mounting locations. For high-stress connection points, two Grade 8 7/16-14 x 1 inch UNC hex bolts deliver the strength needed to handle drivetrain loads without stretching or backing out.

Two Grade 5 6mm-1.0 x 16mm hex bolts round out the fastener selection for accessory mounting points. Lock washers in 7/16-inch sizing are included to prevent loosening under vibration. Each fastener is sized and graded for its specific location in the assembly - the right hardware in the right place every time.

This kit is designed specifically for steel bellhousing installations. Aluminum bellhousings use different bolt lengths due to material thickness differences. Compatible with Chevrolet LS engines paired with TREMEC T56 Magnum transmissions.

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.

Kit Includes

• Lightened billet steel flywheel with 168-tooth ring gear
• Precision-machined friction surface
• Lifetime tech support from MDL

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

• Cost-effective upgrade over stock gray cast iron flywheels for high-performance street engines

Description

When you're building a 383 stroker or freshening a 400 small block Chevy, the flywheel choice matters more than most builders realize. Gray cast iron flywheels work fine for stock applications, but they shouldn't be associated with high horsepower, sticky drag radials, or engines that see more than 6,000 rpm. This nodular iron flywheel solves that problem by delivering the ductility and impact resistance your performance build demands -- without the expense of stepping up to billet steel.

Nodular iron (also called ductile iron) gets its strength from an alloying process that converts gray iron's crack-promoting graphite flakes into spheres, or nodules. This microstructural transformation gives the metal superior ductile characteristics with advantages over gray iron in yield strength, elongation, and impact resistance. For a high-performance street engine that sees spirited driving but doesn't require SFI certification for organized competition, nodular iron represents the sweet spot between cost and capability.

The 400 SBC and aftermarket 383 strokers built on 400 cranks require externally balanced flywheels with weighted counterbalance -- you cannot use a neutral-balance 350 flywheel. This 168-tooth configuration matches the larger flywheel diameter common in truck and full-size applications and provides proper starter engagement. The six-bolt crankshaft mounting pattern secures directly to your two-piece rear main seal crankshaft, and the 12-5/8" equidistant clutch bolt pattern accepts industry-standard pressure plates.

Each flywheel is precision machined to specification after casting, then balanced and inspected for quality and fitment. Compatible with single disc clutches up to 11 inches in diameter, giving you flexibility in clutch selection for your power level and driving style. Fits 1970-1985 Chevrolet 383 and 400 engines with two-piece rear main seal cranks.

What's Included

• Nodular iron flywheel with 168-tooth ring gear
• External balance weight configuration

Key Features

• Billet steel construction for superior strength over cast iron in high-torque applications
• External balance weighting matched to Chevy 400 and 383 stroker crankshaft requirements
• 168-tooth ring gear for improved starter leverage on big-inch, high-compression engines
• 6-bolt crankshaft flange with 3.580-inch bolt pattern for 2-piece rear main seal blocks
• 2.485-inch crank register bore ensures precise crankshaft alignment
• Accepts 11-inch clutch assemblies with 12-5/8-inch pressure plate bolt pattern
• Direct fit for 1970-1985 Chevy 400 and externally balanced 383 stroker builds
• Made in the USA

Description

The Chevy 400 small block and 383 stroker combinations share a common challenge: they require externally balanced rotating assemblies. Unlike internally balanced engines where all counterweight mass lives on the crankshaft, the 400's longer 3.75-inch stroke demanded offset weight on both the harmonic balancer and flywheel to achieve proper balance. This MDL billet steel flywheel carries the correct external balance weighting to eliminate vibration and ensure smooth operation throughout the RPM range.

Billet steel construction delivers significant advantages over factory-style cast iron flywheels in performance applications. Cast flywheels can crack or fail catastrophically under high-RPM use, while billet steel provides the structural integrity these high-torque engines demand. The precision-machined clutch surface is ready for installation with your choice of 11-inch clutch assemblies using the 12-5/8-inch bolt pattern.

The 168-tooth ring gear provides better mechanical advantage for your starter motor, reducing amperage draw and improving cranking performance on high-compression builds. The larger diameter ring gear was factory equipment on all 400 small blocks and is the proper choice when running externally balanced 383 stroker combinations with 400 crankshafts. Note that the 168-tooth flywheel requires a starter with the diagonal (offset) bolt pattern.

Engineered specifically for 1970-1985 two-piece rear main seal Chevy blocks, this flywheel features the correct 6-bolt mounting pattern with 3.580-inch bolt circle and 2.485-inch crank register bore. Whether you're building a numbers-matching 400 restoration or assembling a streetable 383 stroker, this American-made billet flywheel provides the foundation for a reliable, vibration-free manual transmission swap.

What's Included

• Billet steel flywheel with 168-tooth ring gear
• External balance weight for Chevy 400/383 stroker applications

Description

When you need to shed rotating weight without sacrificing reliability, this billet aluminum flywheel delivers the performance advantage serious builds demand. Aluminum construction significantly reduces rotational mass compared to cast iron or steel units, allowing the engine to rev faster and respond more sharply to throttle inputs - critical for track applications where every millisecond of engine response matters.

This flywheel is precision-machined from billet aluminum and features a riveted steel clutch facing that ensures the ring gear stays permanently attached to the flywheel body. Unlike press-fit or interference-fit ring gears that can walk off under high-RPM abuse, this riveted design eliminates separation concerns. The 168-tooth configuration provides proper starter engagement for 1986 and later Chevy 5.7L applications that require external balance.

Six mounting bolts secure the flywheel to the crankshaft using 7/16" hardware, while the 12-5/8" pressure plate bolt pattern accommodates standard 11" clutch setups. Built specifically for external balance 5.7L engines with one-piece rear main seals, this flywheel eliminates the guesswork in engine balancing for '86-up Gen II small blocks. It is recommended to warm the flywheel before installation to ensure proper thermal expansion during mounting.

Note: Aluminum flywheels store and transmit less inertia than steel units. While this improves throttle response, it also makes the engine easier to stall at low RPMs. If pairing with a dual-disc clutch set, the added disc mass offsets some of this effect. Aluminum flywheels should never be paired with ceramic or bronze clutches due to the added heat they generate. Made in the USA.

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. Note: This kit requires a flat-style flywheel with a crank relief of 6.250" or less for proper fitment - it will not work with recessed or stepped flywheels.

Compatible with 1955-1985 Chevy V8 applications using transmissions with a 26-spline x 1-1/8" input shaft. Break-in requires 500-750 miles of stop-and-go city driving to properly seat the discs - actuate the clutch 1,200-1,500 times before any wide-open throttle driving. Pilot and throwout bearings sold separately. Backed by lifetime technical support from Modern Driveline.

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

Second-gen F-body manual transmission conversions have long been plagued by heavy pedal effort and poor clutch modulation. The typical approach--mounting a short-stroke master cylinder directly to the pedal--results in excessive firewall loading and a pedal feel that makes stop-and-go traffic miserable. The MDL Light Foot (LF) Series Master Cylinder Kit solves these problems with an engineered system that delivers light pedal effort and precise clutch control.

The heart of the system is a 0.750-inch bore, 1.4-inch stroke aluminum master cylinder that generates the fluid volume required by today's hydraulic slave cylinders while minimizing firewall load. The master cylinder mounts on a steel firewall support plate that installs behind your brake master cylinder or booster--the strongest point on the firewall. This eliminates the flexing and spongy pedal feel that occurs when master cylinders are mounted to unsupported firewall sections.

The master cylinder positions directly in front of the clutch pedal and uses the stock clutch rod hole, maintaining the original pedal geometry GM engineers designed for proper leverage. This lets you capture the factory full swing of the pedal for maximum mechanical advantage. The remote plastic reservoir features OE-quality construction with integrated fittings--no clamps or hose connections that can develop leaks over time. The complete hydraulic system works seamlessly with both internal hydraulic release bearings like the Tilton 6000 Series and external slave cylinder setups.

Description

Swap out that tired factory knob for the shifter ball that's been the performance standard for over five decades. When you glance into a serious build and see a chrome stick topped with a white cue ball, you know instantly that the driver takes performance seriously. This isn't nostalgia for its own sake -- it's about installing the same proven design that earned its reputation in the golden age of American muscle.

The molded-in brass thread insert is the key to eliminating the wobble and play that plagues cheap knock-offs. That solid connection to your shifter lever translates directly to more precise, confident shifts. The 1-7/8" diameter sits naturally in your palm -- large enough for positive grip, compact enough for rapid gear changes without fumbling. The high-gloss white finish and engraved shift pattern provide a clean, classic look that pairs perfectly with chrome shifter sticks.

Through careful engineering and high-quality materials. The 3/8"-16 thread specification fits aftermarket Hurst chrome shifter sticks and other compatible applications. Note: This thread pitch is not compatible with modern OEM metric applications or pre-1975 Hurst shifters (which used 3/8"-24 fine threads -- verify your shifter's thread specification before ordering).

What's Included

• White 6-speed shift ball with engraved pattern (1-7/8" diameter)
• Molded-in brass thread insert (3/8"-16)
• Jam nut for secure installation

Key Features

• 1-7/8" diameter for optimal grip and precise shift control
• High-gloss, high-strength polymer resin construction
• Molded-in brass thread insert for long-term durability under hard shifts
• Engraved inlaid 6-speed shift pattern with upper-right reverse
• 3/8"-16 coarse thread fits most Hurst chrome shifter sticks

• Temperature-stable material — won't heat-soak like bare metal knobs

Description

One glance at that chrome stick and classic ball knob tells everyone in the car that you mean business. This black 6-speed version delivers the same iconic feel with a more subdued appearance while maintaining Hurst's commitment to precision shifting.

The 1-7/8" diameter has been refined through decades of real-world use to hit the ideal balance between a satisfying, substantial feel and quick, precise shift control. The high-gloss, high-strength polymer construction is a deliberate engineering choice, not a budget compromise. Polymer doesn't heat-soak the way bare metal does — anyone who has grabbed a polished aluminum knob after the car has been sitting in a summer parking lot knows the exact burn. The Hurst ball stays at a manageable temperature in hot weather and doesn't become an ice cube in winter. It's a practical choice wrapped in a beautiful package.

The molded-in brass thread insert ensures the threads hold up under real driving forces — the torque of a hard shift, vibration from a performance engine, and years of daily use without degrading. Plastic threads, by contrast, eventually strip out. Hurst doesn't cut corners here, and that investment in quality shows up in the long-term ownership experience. The 3/8"-16 thread size is the standard coarse-thread specification used on the vast majority of Hurst aftermarket chrome shifter sticks.

Through careful engineering and by using only high-quality components, Hurst shift levers and shift balls complete your vehicle's look — all backed by the history, heritage, and knowledge that Hurst has acquired over half a century of shifter design.

Description

The factory shift knob in your manual transmission rarely delivers the tactile feedback and visual presence a performance build deserves. This MDL-branded 6-speed shift ball delivers both - a properly weighted, ergonomic design paired with the correct shift pattern for TREMEC T56 applications. The 1-7/8" diameter fills your palm for confident, positive shifts without the slop or uncertainty of undersized factory knobs.

Built from solid high-gloss, high-strength polymer, this shift ball handles the temperature swings and mechanical stress of spirited driving without cracking, fading, or softening. The engraved inlaid shift pattern shows reverse positioned to the right and up - the correct layout for 2003-2004 Cobra, 2007-2014 GT500, and any Mustang running an aftermarket TREMEC T56 transmission. Unlike printed or stickered patterns, the engraved inlay won't wear away from years of palm contact.

The molded-in brass threaded insert accepts the 3/8"-16 thread pattern common to most aftermarket performance shifters. Brass eliminates the aluminum-on-aluminum thread galling that plagues cheaper shift knobs, and the included jam nut locks the ball in place so it won't back off under vibration during hard use. The included 16mm thread reducers expand compatibility to metric-threaded shifter applications.

Note: This shift ball requires a shifter or shift handle with a 3/8"-16 thread pattern. It will not fit stock Ford shifters from 2007-2010 Mustangs, which use different thread patterns.

Description

Worn, faded shift knobs kill the look of an otherwise clean build - and cheap replacements crack, fade, or spin loose within a season. MDL's 6-Speed Black Shift Ball solves both problems with a high-impact polymer resin formulation specifically engineered for the automotive industry. This isn't generic plastic - it's a performance-grade compound designed to resist stress cracking with age while handling the torque and temperature extremes of hard driving.

The white 6-speed shift pattern is subsurface - meaning it's embedded beneath the outer layer, not printed or painted on top. It won't wear off from palm contact, won't fade from UV exposure, and won't peel at the edges. The 16mm x 1.50 brass master insert is equally overbuilt, exceeding the auto industry's specification of 200 ft. lbs. static pull and 20 ft. lbs. twist torque. Precision machining and polishing deliver a high-gloss finish that looks as good as it feels.

The 16mm thread pitch fits most aftermarket performance shifters directly. If your shifter uses a different thread size, MDL stocks thread adapters to match - just know your shifter's thread pitch when ordering so we can recommend the right reducer. This universal approach makes the shift ball compatible with Ford, GM, and Mopar applications when properly matched to your shifter.

At 4 ounces with a 1-7/8" diameter, this shift ball delivers ergonomic comfort and balanced weight for crisp, confident throws. Made in the USA with the quality standards serious builders demand.

Description

Printed and painted shift patterns wear off - it's only a matter of time before your gate markings fade into an unreadable smear. MDL's 6-speed shift ball solves that problem permanently. The shift pattern is laser-etched directly into the surface, creating a crisp, deep marking that stays readable for the life of the knob regardless of how many shifts you put through it.

The gray brushed aluminum finish delivers a subdued, professional look that complements both classic and modern interiors without screaming for attention. At 2-1/8" diameter, the ball offers enough surface area for a solid palm grip while remaining ergonomic for quick gate-to-gate movement. Polymer resin construction keeps the ball durable and lightweight - you won't be fighting unnecessary mass when banging through gears.

Description

After decades of heat cycling, vibration, and exposure to drivetrain temperatures, the original lower shifter boot on your second-generation Camaro has likely cracked, torn, or hardened to the point where it no longer seals. The result is predictable: cold air drafts, dust intrusion, wind noise, and an interior that never quite feels finished. This OEM-style replacement boot restores the critical barrier between your transmission tunnel and cabin.

The lower shifter boot mounts to the transmission tunnel hump, sealing the opening where your shifter mechanism passes through the floor. This keeps cold air and dust from entering the passenger compartment through the shifter opening. When the original rubber degrades, you lose that environmental seal completely -- allowing road grime, exhaust fumes, and temperature extremes direct access to your interior.

Molded from durable rubber to match factory specifications, this boot fits all '70-'81 Camaro models equipped with manual transmissions, whether you're running a 3-speed or 4-speed gearbox.

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

Key Features

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

Description

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

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

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

Kit Includes

• 18-tooth yellow speedometer driven gear

Key Features

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

Description

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

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

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

What's Included

• One 19-tooth speedometer driven gear (pink)

Key Features

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

Description

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

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

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

What's Included

• One 20-tooth driven speedometer gear (black)

Key Features

• 21-tooth red gear follows Ford's factory color-coding system for manual transmissions

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

• Three-wire design with included 10-foot pigtail harness for flexible routing and clean signal transmission
• Allen-head mounting bolt provides body clearance in tight transmission tunnel applications
• Uses standard T5 driven speedometer gears - no adapter required for low-profile installation.
• Compatible with Ford T-5, T-45, TR3550, 5-speed and 6-speed Ford T-56, and Magnum transmissions (requires Ford-driven speedometer gears and retainer clip)

Description

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

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

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

What's Included

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

• Compatible with Classic Instruments, Auto Meter, Dakota Digital, and GM Connect & Cruise packages

Description

Converting to a TREMEC 6-speed Magnum means wiring three critical electrical functions: the vehicle speed sensor, reverse lockout solenoid, and reverse lights. Traditionally, this required up to five separate components—signal converters, lockout controllers, pigtails, and individual harnesses—all needing integration. The Bowler 3-in-1 Harness consolidates everything into a single pre-wired solution with an intelligent, Bluetooth-configurable controller.

The T56 Magnum and TR6060 place reverse gear dangerously close to 5th gear, creating real potential for accidental engagement at highway speed. The reverse lockout solenoid uses a spring-loaded pin to resist shifts into reverse when de-energized. Most DIY wiring ties the solenoid to the brake light switch—a flawed approach since braking at speed still allows reverse engagement. This harness uses speed-based control like the OE system: the lockout engages above 4 MPH and releases only when the vehicle slows to 0-3 MPH. These thresholds are fully adjustable through the free smartphone app.

The dual speed sensor outputs solve one of the most frustrating wiring challenges in modern builds. Your ECM may need a different signal than your electronic speedometer or cruise control, forcing multiple converters. This harness provides two completely independent outputs—each calibrated separately with any pulse count and ratio you need. The outputs generate a square wave signal from approximately -5V to +5V, and automatically shift to 0V to +10V when your ECM requires a positive-only input. Works seamlessly with popular gauges from Classic Instruments, Auto Meter, and Dakota Digital.

The compact epoxy-sealed controller mounts directly to the VSS output using the existing bolt—no additional mounting hardware or locations needed. Power comes from a switched +12V circuit with ground to the negative battery post or engine block. This harness fits Ford & GM Standard T56 Magnum and Ford TR6060 transmissions. Note: Does not work with 2019 and newer Mustang ECM (Wavelength system).

What's Included

• Epoxy-sealed Bluetooth controller module
• Pre-wired harness with VSS connector
• Reverse lockout solenoid wiring and connector
• Dual vehicle speed sensor output leads (pre-set 40-pulse and 16-pulse)
• Reverse light activation wire
• Protective wiring loom
• Mounting hardware for VSS bolt installation
• Installation instructions and app guide
• Free iOS/Android Bowler app download

Key Features

• Direct-fit snap-in connector mates with the reverse lockout solenoid on all TREMEC T56 6-speed transmissions
• Generous 6-foot wiring length provides flexible routing through tunnels and firewalls
• Protective covering shields wiring from heat, abrasion, and moisture
• Designed for use with MDL's MD-700-0100-2 reverse lockout control module
• Fits Ford and GM T56 applications

Description

The TREMEC T56 utilizes a reverse lockout solenoid to prevent accidental shifts into reverse while attempting to engage 5th gear--a critical safety feature because reverse and 5th are located very close to each other on the shift pattern. When the solenoid isn't energized, spring pressure against the shift rail makes reverse engagement difficult. When powered, the solenoid retracts the pin, allowing smooth entry into reverse. The problem? Classic cars and restomod builds lack the factory PCM logic to control this solenoid, leaving builders to either muscle through the lockout or rig up makeshift solutions.

This 6-foot harness provides the factory-style snap-in connector that mates directly with the T56's reverse lockout solenoid. The extended length gives you the flexibility to route wiring cleanly through the transmission tunnel, up through the firewall, and to your control module location without splicing or extending. The protective covering shields the conductors from exhaust heat, sharp edges, and underbody moisture--critical for a harness that lives in a harsh environment.

This harness is designed to work with MDL's MD-700-0100-2 reverse lockout control module, which monitors vehicle speed via the VSS signal and automatically energizes the solenoid below approximately 5-10 MPH for easy reverse engagement, then de-energizes it at higher speeds to prevent accidental shifts. The result is OEM-style lockout behavior without relying on makeshift brake-light-switch wiring or manual override buttons. Fits all TREMEC T56 6-speed transmissions in Ford and GM applications.

What's Included

• 6-foot reverse lockout solenoid harness with protective covering
• Snap-in connector for TREMEC T56 reverse solenoid

Key Features

• Direct-fit connector for Ford T5, all TKO variants, TKX, and T56 transmissions equipped with two-prong round body reverse switches
• Plug-and-play installation eliminates splicing, cutting, and custom wiring
• Factory-style connector ensures secure electrical contact for reliable backup light operation
• Does not fit Magnum or Magnum XL transmissions (different switch configuration)

Product Overview
