Description

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

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

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

The TKX bolts directly to standard GM Muncie bellhousings, making it a direct replacement for 3-speed and 4-speed Muncie transmissions. The 26-spline input shaft requires a matching clutch disc, while the 31-spline output shaft provides increased strength for high-torque applications. Includes a high-performance short-throw billet aluminum shifter that isolates road noise while delivering clean, crisp shifts. Like all TREMEC aftermarket transmissions, the TKX is made from 100% brand-new OEM-quality components.

Description

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

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

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

Bolts directly to existing GM Muncie bellhousings or Quicktime SFI-approved bellhousings. The GM-pattern input features a 0.590 in. pilot tip and 1.375 in. OD throwout bearing guide tube.

• Includes both bellhousing-to-engine and transmission-to-bellhousing fasteners
• Eliminates parts-counter guesswork with application-specific hardware
• Designed specifically for aluminum bellhousing installations
• Note: For early LT engines, use HWkit-TKX Chevy AL instead

Description

Bolting a TREMEC TKX to an LS or late model LS-based LT1/LT4 engine with an aluminum bellhousing requires specific hardware that the factory never intended to supply. This MDL install hardware kit provides the correct fasteners for both the bellhousing-to-engine block and transmission-to-bellhousing connections, eliminating trips to the hardware store and the headache of sourcing individual bolts with the right thread pitch and length.

The TKX uses a GM-style bolt pattern that shares commonality with classic small-block Chevys, but aluminum bellhousings demand specific bolt lengths to properly engage the softer material without bottoming out or stripping threads. This kit is matched to the dimensional requirements of LS-series (Gen III/IV) and late model LS-based LT1/LT4 (Gen V) engines when paired with aftermarket aluminum bellhousings.

Important: This hardware kit is designed specifically for late model LS-based LT1/LT4 engines. If you're running an early LT engine (1992-1997 LT1/LT4), you'll need the HWkit-TKX Chevy AL kit instead. The bolt patterns are similar but the hardware specifications differ between generations.

Whether you're building a resto-mod with an LS swap or adding a TKX to a late-model Corvette or Camaro powerplant, this kit ensures you have the right fasteners from the start. One less variable to troubleshoot during your transmission installation.

What's Included

• Bellhousing-to-engine block bolts for LS/late model LT1/LT4

Description

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

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

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

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.

Description

Factory flywheel bolts are a weak link in high-performance LS builds. OEM hardware simply is not engineered to handle the stress of aggressive clutch dumps, high-RPM shifts, or sustained track use. 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

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. This assembly does not include a pilot bearing or throwout bearing - it can be used with most OEM release bearings, or pair it with a Tilton 6000-Series hydraulic release bearing for optimal performance.

Kit Includes

• Billet chromoly steel flywheel with integrated 168-tooth ring gear (internally balanced)
• Precision-machined aluminum clutch cover
• High-mass pressure plate (proprietary racing materials)
• Heavy-duty floater plate (2x thickness vs. competitors)
• Two cerametallic clutch discs with solid-hub centers (26-spline x 1-1/8")

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

• 1.096" outer diameter x 0.590" inner diameter - sized for TREMEC input shafts
• 0.720" width provides proper input shaft support depth
• Inner landing design fits the innermost pocket of LS crankshaft flanges
• Sealed bearing construction prevents contamination and lubricant loss
• Correct bearing for LS3 T-56 conversion applications and similar setups
• Compatible with GM LS1, LS3, and LS6 engines

Description

Selecting the correct pilot bearing for an LS engine and TREMEC transmission combination is critical - the wrong bearing position or size leaves the input shaft unsupported, causing shifting issues and accelerated transmission wear. This sealed pilot bearing is engineered for applications requiring the small-diameter bearing that seats in the innermost pocket (Position A) of the LS crankshaft flange.

The 1.096" outer diameter press-fits into the inner landing of LS1, LS3, and LS6 crankshafts, while the 0.590" bore matches the pilot tip diameter of standard TREMEC T-56, Magnum, and TKO input shafts. The 0.720" width ensures adequate support depth at the pilot tip - the most critical point for maintaining input shaft alignment and preventing premature bearing failure.

Use this bearing when your transmission input shaft protrudes approximately 3/4" to 1" past the front face of the bellhousing. For T-56 conversions behind LS3 engines using aftermarket bellhousings, this is typically the correct bearing position. Always verify input shaft protrusion and crankshaft pocket dimensions before installation - the bearing should be a slight interference fit into the crankshaft. Install by pressing on the outer race only, and ensure the sealed side faces outward (toward the transmission) to retain lubrication.

Description

Converting your first-gen Camaro, Firebird, or early Nova to hydraulic clutch actuation does not have to mean compromising pedal feel or dealing with firewall flex. The common approach - bolting a 3/4" or 7/8" bore by 1" stroke master cylinder directly to the pedal - results in improper pedal pressure, heavy effort, and often requires raising the cylinder higher than the stock clutch rod hole. The MDL LF Series solves these problems with an engineered mechanical linkage system that preserves factory pedal geometry while delivering modern hydraulic performance.

The heart of this kit is the 0.750" bore master cylinder with a 1.4" stroke, producing 0.619 cubic inches of fluid volume - the sweet spot for most aftermarket internal and external slave cylinders. The mechanical linkage allows the full stroke of the pedal to maximize clutch modulation while keeping the cylinder perpendicular to the firewall, providing mechanical advantage that reduces the pedal pressure required to operate the clutch. The firewall plate mounts under your brake master cylinder or booster where the structure is strongest, eliminating flex under load.

The silver anodized billet aluminum reservoir provides a premium appearance while eliminating the leak-prone clamp connections found on cheaper systems. Every kit includes comprehensive installation instructions and MDL's unique One-Man Bleeder Kit, making the bleeding process straightforward even for first-time hydraulic installers.

Description

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

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

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

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

• Made in the USA

Description

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

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

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

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

What's Included

• White polymer resin shift ball with subsurface 5-speed pattern
• 16mm x 1.50 brass master insert (pre-installed)
• Jam nut

Key Features

• Side-mounted push button lockout prevents accidental reverse gear engagement
• High-impact polymer resin construction engineered for performance torque and temperature demands

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

Description

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

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

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

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

Description

Adding switch control to your shifter shouldn't mean clunky add-ons or taking your hand off the lever mid-shift. This 5-speed black shift ball puts a side-mounted momentary push button exactly where your thumb naturally rests, giving you instant access to nitrous activation, line lock, or other electrical accessories without fumbling for a dashboard switch or console button.

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

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

Perfect for street/strip builds, drag applications, or any 5-speed manual transmission setup where you need reliable switch control at your fingertips.

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

This is the shift lever that defined an era. The Hurst chrome-plated round bar stick was the upper bolt-on stick originally supplied from Detroit factories for vehicles that were "Hurst Equipped." The chrome round bar design, bolt-on construction, Hurst logos, and white ball knob were the identifying features that signified a Hurst shifter was installed at the factory as original equipment. For years, these OEM round bar sticks were never sold to the general public - they were only available if you bought a vehicle optioned with a Hurst shifter from the dealer.

Now this OE-style stick is available directly from Hurst, with all the great features exactly as originally designed. Built from forged steel with high-quality chrome plating, this shift lever delivers the authentic look and durability that made Hurst "America's Number 1 Shifter Company." The iconic "HURST" name is stamped directly into the stick, providing the period-correct detail that separates genuine Hurst hardware from generic alternatives.

The 11.21-inch height with 3.75-inch setback creates the classic curved geometry that puts the shift knob exactly where it belongs for smooth, confident shifts. This lever is particularly popular for 1969 Camaro and Firebird builds, fitting factory console installations as well as period-correct Muncie 4-speed shifters. Modern builders will appreciate that it also works perfectly with TREMEC TKX, TKO, and T56 Magnum transmissions paired with Hurst-pattern shifter mechanisms.

The universal 3/8"-16 TPI thread accepts all Hurst shift knobs and T-handles, giving you complete control over the final appearance. Whether you're completing a concours-level restoration or building a restomod that honors classic muscle car heritage, this chrome round bar shift lever delivers the authentic Hurst experience.

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.

• Direct fit for Ford T5, T45, TKO, TKX, and T56 Magnum transmissions
• Precision-molded construction for smooth, reliable operation

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

• 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

• Fits all TREMEC transmissions using Ford-style speedometer systems: T5, T45, TKO, TKX, and T56 Magnum
• Precision molded nylon construction for smooth, quiet operation and long service life
• Direct drop-in replacement--no modifications required

Description

Swapping to a 5 or 6-speed TREMEC transmission changes your final drive ratio, which throws off your factory speedometer calibration. This 21-tooth red driven gear lets you recalibrate your mechanical speedometer to read accurately with your specific tire size and rear axle ratio combination--no electronic tuner required.

Ford has used a consistent color-coding system for manual transmission speedometer gears since the 1960s: 16-tooth wine, 17-tooth white, 18-tooth yellow, 19-tooth pink, 20-tooth black, and 21-tooth red. As the largest tooth count in the standard range, this red 21-tooth gear provides maximum correction for applications with taller tires or numerically higher axle ratios. Each tooth of difference adjusts your speedometer reading approximately 5-6%, so selecting the correct count is critical for accuracy.

The driven gear installs into the speedometer housing on the tailshaft of your transmission, where it meshes with the drive gear on the output shaft. TKO, TKX, and T56 Magnum transmissions come from the factory with a 7-tooth drive gear, making this 21-tooth driven gear the correct starting point for common combinations like 3.55 or 3.73 rear gears with 26-inch or taller tires. Use a speedometer gear calculator with your actual tire diameter and axle ratio to confirm the correct tooth count for your build.

This gear is compatible with Ford T5, T45, TKO, TKX, and T56 Magnum transmissions. The driven gear works with both cable-driven and VSS-equipped speedometer systems--just swap it into your existing housing.

What's Included

• 21-tooth red speedometer driven gear (precision molded nylon)

Key Features

• Secures driven speedometer gear for proper placement and operation in Ford T5 transmissions
• Direct replacement for original clips that have become brittle from heat exposure
• Essential component for automatic-to-manual conversions where no clip exists
• Compatible with all Ford T5 transmissions

Description

Clip-style speedometer gears require a retaining clip to lock the driven gear securely in the transmission housing, and this replacement clip delivers the secure fit your Ford T5 needs. Without a properly functioning clip, the driven speedometer gear can back out of the housing during operation, causing inaccurate speedometer readings and potential fluid loss.

Original retaining clips often become brittle after years of heat cycling in the transmission environment. If you're servicing your Ford T5, T-45, T-56, TKO/TKX, and Magnum speedometer gear or coming from an automatic transmission that didn't use a mechanical speedometer setup, a new retaining clip ensures your driven gear stays exactly where it needs to be. This is an inexpensive detail that makes the difference between a speedometer that works reliably and one that gives you trouble down the road.

This clip is the correct fitment for all Ford T5 transmissions and works with standard Ford-style driven speedometer gears. Keep one on hand whenever you're doing speedo gear service work.

Description

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

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

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

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

Description

Swapping a modern TREMEC 5-speed into your first-gen F-body or X-body means the factory crossmember has to go. It wasn't designed for TKO or TKX transmissions, and trying to make it work usually means fighting clearance issues and compromising your exhaust routing. This Bowler tubular crossmember solves the problem with a purpose-built design that properly supports your TREMEC while maintaining room for the dual exhaust setup your build deserves.

The tubular steel construction delivers the strength these high-torque applications demand without the bulk of a stamped-steel crossmember. That slim profile is the key to exhaust clearance - you won't be forced into single-pipe compromises or custom bends to clear the transmission mount. The black powder coat finish provides long-term corrosion resistance and a clean, professional appearance under your car.

Installation is straightforward bolt-in work to your existing frame mounting points - no drilling, cutting, or welding required. The crossmember works with both stock height and 1/2 height body bushings, giving you flexibility regardless of how your car sits. It's compatible with small block Chevy engines, and LS swaps are supported as long as the engine is positioned in the factory small-block location. This crossmember will not work with setback LS installations, so verify your engine mounting configuration before ordering.

This crossmember fits '67-'69 Camaro and Firebird F-bodies, plus '68-'72 Nova X-bodies. It supports TREMEC TKO-500, TKO-600, and TKX 5-speed manual transmissions, and also works with the 700-R4 automatic for those running a slushbox.

Description

Connecting your transmission to the driveshaft demands a slip yoke that can handle real power without becoming a weak link. This Neapco 31-spline forged steel slip yoke delivers the strength and precision fit required for Ford TKO, C6, and FMX transmissions, providing a direct-fit solution for street performance builds.

Forged steel construction eliminates the porosity and stress risers inherent in cast yokes. The result is a stronger, more consistent part that handles torque loads without cracking or deformation. The 1310 Series U-joint is rated for 400 lb-ft of continuous torque and 800 lb-ft short-duration loads--making this combination well-suited for street-driven cars producing up to approximately 500 hp, provided traction is managed with street tires rather than slicks.

Neapco's precision broaching process produces tight-tolerance spline fits that mate smoothly with the transmission output shaft. This accuracy, combined with reduced end play in the universal joint, minimizes driveline vibration and extends component life. The outside snap ring design allows for straightforward U-joint service when maintenance is eventually needed.

This slip yoke fits Ford transmissions with 31-spline output shafts, including the Ford TKO, C6 automatic, and FMX automatic. If your application requires higher torque capacity, consider upgrading to a 1330 or 1350 Series yoke and matching driveshaft components.

Description

Converting to a TREMEC TKX, TKO, or Magnum often means your factory slip yoke is no longer up to the task. The increased torque from a modern 5-speed or 6-speed manual transmission demands a properly matched slip yoke that can handle the load without becoming a weak link in your driveline. This 31-spline slip yoke solves that problem with the proven 1330 series dimensions and D550 ductile iron construction.

The forged steel construction provides the tensile strength needed for high-torque applications while maintaining the precise tolerances required for smooth, vibration-free operation. The 1330 series u-joint dimensions - 3-5/8" overall width with 1-1/16" bearing caps - deliver more driveline angle capability than the smaller 1310 series while keeping overall packaging compact. Outside snap rings secure the u-joint caps, making future service straightforward without specialized tools.

The 31-spline internal configuration directly matches the output shaft splines on TREMEC TKX, TKO, and Magnum transmissions, as well as some T56 variants, Ford C6 automatics, and FMX transmissions. Built by Neapco to OEM standards, this slip yoke bridges the gap between your transmission upgrade and your existing driveshaft, accepting standard 1330-series u-joints for flexibility in choosing greaseable or sealed units based on your application.
