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 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.

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.

Description

The LS9's supercharged 6.2L V8 didn't just get more horsepower than its LS siblings--it got a completely different flywheel bolt pattern. While standard LS engines use a 6-bolt crankshaft flange and newer LSA/LT variants moved to 8 bolts, the LS9 stands alone with its 9-bolt configuration. This kit delivers all nine bolts you need to properly secure your flywheel to that unique crankshaft flange.

Each bolt features M11-1.5 threading with 23.5mm length, matching GM's factory specifications exactly. Proper installation requires a three-pass torque sequence: first tighten all bolts to 15 lb-ft, then 37 lb-ft, and finally 74 lb-ft in a crisscross pattern. This graduated approach ensures even clamping force distribution across the flywheel face, preventing the distortion and bolt loosening that plague improperly torqued assemblies. Incorrect flywheel bolt torque on high-output LS engines can cause bolts to back out, destroying the clutch assembly and eventually damaging rod bearings and transmission components.

Whether you're building a Corvette ZR1 restoration, dropping an LS9 crate engine into a swap project, or refreshing an existing clutch setup, this complete nine-piece kit ensures you have the correct hardware on hand. No more hunting for individual bolts or questioning whether you have the right count for that distinctive 9-bolt pattern.

ARP's Pro Series Flywheel Bolt Kit delivers the strength upgrade serious LS builders demand, replacing marginal factory fasteners with aerospace-grade hardware rated at 200,000 psi tensile strength.

Each bolt is forged from 8740 chromoly steel - a nickel-chromium-molybdenum alloy prized for its exceptional balance of tensile strength, toughness, and fatigue resistance. ARP heat-treats the material before thread rolling and machining, a critical sequence that maximizes thread integrity and dimensional accuracy. The exclusive flat 12-point head design accepts a standard 1/2-inch socket and provides superior engagement compared to hex heads, reducing the risk of rounding under high torque loads.

The larger-than-stock shank diameter does more than just add strength - it improves flywheel register by filling more of the mounting hole, reducing the chance of flywheel movement under load. The 0.880-inch under-head length is engineered specifically for LS Series crankshafts, ensuring proper thread engagement without bottoming out. Black oxide finish provides corrosion protection while maintaining the professional appearance serious builders expect.

Compatible with LS1, LS2, LS3, LS6, LS7, and L92 series engines. Complete 6-bolt set includes everything needed to secure your flywheel with confidence.

Description

Extracting maximum performance from a high-torque LS engine requires a clutch that bridges the gap between aggressive track bite and civilized street manners. This dual-friction Superior clutch disc solves that challenge by pairing Kevlar on the flywheel side with a steel-backed organic facing on the pressure plate side. The result is a clutch that hooks hard under load yet remains smooth and predictable in stop-and-go traffic.

Why the hybrid configuration? Kevlar's coefficient of friction actually increases with temperature—meaning torque capacity goes up, not down, under hard use. It also resists burning and delivers exceptional longevity. Meanwhile, the steel-backed organic side provides the smooth modulation and forgiving engagement drivers expect on the street. This combination delivers more grip than a pure organic disc while maintaining better driveability than an all-Kevlar setup—the sweet spot for street performance and weekend track duty.

Every Superior clutch disc is hand-built in MDL's Caldwell, Idaho facility. Each disc goes through rigorous quality control—checked and double-checked for tolerances—before it ships. The 11" diaphragm pressure plate provides high clamping force without excessive pedal effort, and the sprung hub dampens engagement shock for chatter-free operation. Rated at 500 lb-ft, this kit is sized right for naturally aspirated and moderately boosted LS builds.

Fits GM LS engines paired with T56 or T56 Magnum transmissions using a 26-spline, 1-1/8" input shaft. Designed exclusively for hydraulic clutch actuation systems. Note: No throwout bearing or pilot bearing included—order separately based on your bellhousing and crankshaft configuration.

Description

High-performance LS builds demand clutch systems that can handle serious power while maintaining streetability. The MDL Superior 11" Kevlar clutch set delivers exactly that balance—rated at 550 lb-ft of torque capacity with dual Kevlar friction surfaces that actually increase grip under hard use rather than fading like organic compounds. When heat builds during aggressive driving, Kevlar's coefficient of friction rises, giving you more holding power precisely when you need it most.

Unlike organic materials that lose torque capacity at elevated temperatures and can burn when slipped excessively, Kevlar resists wear significantly better and won't sustain permanent heat damage under demanding conditions. The sprung hub design absorbs drivetrain shock loads, delivering smooth engagement without the chatter common to solid-hub racing clutches. This combination makes the Superior series ideal for vehicles that split time between spirited street driving and open track days.

The diaphragm-style pressure plate provides progressive pedal feel with clamping force that actually increases over the life of the clutch—delivering lower pedal effort than Long-style pressure plates while maintaining consistent performance. The 12-5/8" equal bolt pattern matches standard GM LS flywheel configurations, and the 26-spline x 1-1/8" hub provides direct compatibility with T56 and T5 transmissions.

Every Superior clutch set is hand-assembled in MDL's facility, where each assembly undergoes rigorous inspection to ensure exacting tolerances and flawless operation before it ships. You receive a ready-to-install, precision-balanced clutch set backed by a 1-year free-from-defect warranty.

Description

The McLeod RST twin disc clutch delivers 800hp holding power in a street-friendly package--no harsh engagement, no leg-day pedal effort, no excuses. It's engineered for the enthusiast running serious power who still wants to daily-drive their build without fighting the clutch in traffic.

The twin organic friction discs provide the clamping force of a multi-disc setup while maintaining the smooth, progressive engagement characteristics you expect from a streetable clutch. Sprung hubs absorb driveline shock during aggressive launches, protecting the transmission input shaft while delivering precise pedal modulation. The diaphragm pressure plate maintains consistent clamp load across the RPM range with a lighter pedal feel than Borg & Beck designs.

McLeod's patented adapter ring system is the key to the RST's universal fitment. The large red adapter ring included with this kit bolts directly to large-diameter flywheels--Chevy 168-tooth, Ford 164T/176T/180T/184T, and BOP 160T/166T--eliminating the need for a dedicated flywheel. This covers GM V8 applications from '55-'85, Buick/Olds/Pontiac from '59-'79, and Ford 11"/11.5"/12" Long bolt patterns.

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.

Description

When you're pushing serious power through an LSX or LT4 engine, clutch failure isn't an option. The Tilton ST-246 was engineered from the ground up as a true performance twin-disc clutch - not an OEM-type stamped steel pressure plate with a floater tacked on as an afterthought. This is race-derived technology built for the street, drawing on Tilton's nearly 50 years of championship-winning experience in F1, NASCAR, IMSA, IndyCar, and Formula Drift.

The engineering details set the ST-246 apart. The precision-machined aluminum clutch cover shares technology with Tilton's OT-Series racing clutches, delivering higher strength, better stiffness, and superior dynamic balance compared to stamped steel competitors. The high-mass pressure plate and floater plate are machined from the same proprietary materials used in Tilton's racing clutches, providing exceptional heat capacity and warp resistance. That floater plate runs twice the thickness of typical twin-disc setups - this eliminates gear chatter and provides dramatically better heat dissipation under hard use.

This specific kit features solid-hub cerametallic discs rated for 1,250 lb-ft of torque, delivering the positive, precise engagement characteristics needed for street/strip applications. The billet chromoly steel flywheel includes an integrated 168-tooth ring gear and precision register system that provides optimal clutch-to-flywheel balance - no loose-fitting bolts or dowels like stamped steel units. Heavy-duty straps connect the plates to the cover, minimizing noise while ensuring fast, clean releases between shifts.

Designed for Chevy LSA, LSX, LT1, and LT4 engines with 8-bolt crank flange patterns. Compatible with TREMEC T56, TKO, TKX, and Magnum transmissions via the 26-spline x 1-1/8" input shaft.

Note: Pilot bearing and throwout bearing not included.

Key Features

• 1.094" outside diameter x 0.590" inside diameter - precision-sized for Chevy small block, big block, and GM Gen 6 V8 crankshafts
• 0.500" width for proper crankshaft engagement depth
• Oilite bronze construction - sintered bronze impregnated with oil for self-lubrication throughout service life
• No external greasing required - grease actually seals the pores and reduces lubrication effectiveness
• OEM-specification dimensions ensure proper fit and transmission input shaft support
• Essential for manual transmission swaps using motor mounts or torque plates between engine and bellhousing

Description

A worn or incorrectly sized pilot bushing causes input shaft wobble, accelerates clutch disc wear, and can damage transmission internals. This heavy-duty Oilite bronze pilot bushing provides the precise crankshaft-to-input shaft alignment your Chevy V8 drivetrain demands. The 1.094" OD and 0.590" ID dimensions match OEM specifications for small block, big block, and GM Gen 6 engines originally equipped for manual transmission use.

Unlike standard bronze bushings that require periodic lubrication, this bushing is manufactured from sintered Oilite bronze - a porous material impregnated with oil during production. As the transmission input shaft rotates and generates heat, oil seeps from the microscopic pores to create a continuous lubricating film. When the shaft stops, the bushing reabsorbs the oil. This self-lubricating design eliminates the need for grease application, which actually seals the pores and defeats the purpose of the oil-impregnated construction.

Use this pilot bushing when your drivetrain setup includes motor mounts or torque plates between the engine and bellhousing. The 0.500" width provides proper engagement depth in the crankshaft bore while fully supporting the transmission input shaft snout. For easiest installation, freeze the bushing before pressing it into the crankshaft pilot bore - the thermal contraction eases the interference fit. To remove an old bushing, pack the center cavity with bread and drive out with a punch; this method is far less messy than the traditional grease-pack approach.

This is a wear item that should be replaced with every clutch service, even if it appears serviceable. A fresh bushing costs far less than the transmission teardown required to fix damage from a worn pilot support.

What's Included

• (1) Oilite bronze pilot bushing, oil-impregnated
• Dimensions: 1.094" OD x 0.590" ID x 0.500" width

Key Features

• Heat-treated Grade 8 steel construction with 120,000 psi tensile strength for critical clutch safety
• 3/8-16 thread pitch with 1.000-inch underhead length fits dozens of Ford and Chevy applications

• Hex head design with 9/16-inch wrench diameter for standard tool compatibility
• Lock washers included for secure assembly — companion nuts sold separately
• Set of 6 bolts covers complete pressure plate installation

Description

Pressure plate bolts are often overlooked until they fail — and that failure can destroy your clutch, flywheel, and bellhousing in seconds. These pressure plate bolts eliminate that risk with precision-machined Grade 8 steel construction that delivers the strength and reliability your drivetrain demands.

Each bolt is heat-treated to Grade 8 specifications, providing 120,000 psi tensile strength — the benchmark for high-stress fastener applications. The black oxide finish provides corrosion resistance while maintaining the precise tolerances needed for proper clutch operation.

Description

Converting your 1968-1972 Chevelle or 1967-1972 Buick, Oldsmobile, or Pontiac A-body from mechanical clutch linkage to hydraulics has always meant wrestling with a pile of questions: Which master cylinder fits? How do I connect it to the pedal? Will I have enough pedal stroke to fully release the clutch? The LF Series Master Cylinder Kit answers every one of them in a single bolt-in package designed specifically for your GM A-body.

The secret is MDL's innovative pedal linkage system. Traditional hydraulic conversions bolt a master cylinder directly to the pedal arm, resulting in harsh pedal effort and compromised stroke. The LF Series instead uses a mechanical linkage that matches pedal travel with the master cylinder's long 1.4-inch stroke. This approach maintains the stock clutch pedal pivot point so the pedal feels like factory equipment while the 0.750-inch bore generates enough fluid volume to actuate most aftermarket external or internal slave systems with a smooth, light pedal feel.

The firewall bracket does more than just hold the master cylinder in place. It positions the cylinder at the precise angle required for proper pedal geometry and distributes mounting loads to prevent firewall flex. The silver billet aluminum remote reservoir mounts cleanly on the firewall, keeping your engine bay tidy and making installation straightforward. Whether you're swapping in a 5-speed or simply ditching worn-out mechanical linkage, this kit delivers modern clutch actuation with OEM-quality pedal feel.

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)

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.

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

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.

What's Included

• Thread reducing insert (16mm internal threads, 3/8-24 external threads)
• Jam nut

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
• 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

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

Description

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

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

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

What's Included

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

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

Description

When you install a TREMEC transmission in your build, you need a clean way to send speed data to your electronic speedometer or ECU. This harness provides the critical link between your transmission's output speed sensor (OSS) and your vehicle's existing Ford-style VSS wiring. It's designed specifically for the two-wire analog speed sensor output found on Ford and GM TREMEC Magnum transmissions, as well as Ford TKX, TKO, and T45/3650 units.

The terminals are constructed from tin-plated brass, which resists corrosion and maintains solid electrical contact even in harsh underhood environments. This matters because intermittent speed signals cause erratic speedometer readings and can throw off ECU calculations that rely on vehicle speed data. The Ford VSS connector style was used across a wide range of 1987-1995 Ford vehicles, making this harness the right choice when you're tying into an existing Ford wiring harness or EFI system from that era.

This harness is the simple, direct solution for builders running electronic speedometers with TREMEC 5- and 6-speed transmissions. Whether you're completing a resto-mod Mustang with modern gauges or wiring a GM-pattern Magnum into a classic muscle car, this connector eliminates guesswork and custom splicing.

What's Included

• Electronic speedometer harness with tin-plated brass terminals
• Ford VSS-style two-wire connector

Key Features

• Microprocessor-controlled lockout system prevents accidental reverse engagement above approximately 5 MPH
• Six-wire harness with integrated inline fuse for complete installation
• Universal fitment for all T56, T56 Magnum, and TR6060 transmissions
• Weather-resistant construction - interior mounting recommended for maximum longevity
• Two dedicated wires for solenoid output control
• Two wires for VSS (vehicle speed sensor) signal input
• Switched power and ground connections included
• Eliminates need for brake light switch or manual button workarounds
• Factory-like speed-based operation without requiring an OEM computer

Description

When you swap a TREMEC T56, T56 Magnum, or TR6060 into a classic or performance build, you lose the factory computer's ability to control the reverse lockout solenoid. Without proper control, the transmission becomes prone to inadvertent grinding into reverse gear while attempting to shift into 5th - a common problem since these gears are located very close to each other in the shift pattern. Manual workarounds like wiring to the brake light switch create their own problems: you can step on the brake at highway speed and still accidentally engage reverse.

This Reverse Lockout Control Module solves the problem with intelligent speed-based control. The heart of this module is a microprocessor that continuously monitors vehicle speed through the VSS signal. At low vehicle speeds, the reverse lockout solenoid is energized, retracting the blocking pin and allowing you to shift smoothly into reverse. Above approximately 5 MPH, the module de-energizes the solenoid, locking out reverse gear access and preventing costly transmission damage from an accidental shift. This creates factory-like operation without the need for an OEM PCM or ECM.

The six-wire harness simplifies installation with dedicated circuits: two wires for switched power and ground, two wires for VSS signal input from the transmission speed sensor, and two wires for solenoid output. The integrated inline fuse protects the circuit. While the module features weather-resistant construction, mounting inside the vehicle interior is recommended for maximum longevity. The system requires no special programming or calibration - wire it up and it works.

This module is essential for any T56-family transmission swap where the factory computer control is unavailable. It controls the reverse lockout solenoid found on all Borg Warner and TREMEC T56, Magnum, and TR6060 transmissions, restoring the safety and convenience of proper reverse lockout operation that these transmissions were designed to have.

What's Included

• Reverse lockout control module with microprocessor
• Six-wire harness with color-coded leads
• Inline fuse
• Installation instructions

• Bluetooth-enabled epoxy-sealed controller mounts to existing VSS bolt
• Square wave output: -5V to +5V standard, auto-shifts to 0V to +10V for positive-only ECM inputs
• Replaces up to 5 separate components previously required for full functionality
• Free iOS and Android app for complete signal customization
• 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).

• 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.
