Description

Getting the shifter exactly where you need it in a custom truck or hot rod build can be the difference between a project that works and one that fights you every mile. This MDL-modified TREMEC TKX solves that problem with a professionally machined side shifter featuring front socket configuration and a precisely calibrated 1" or 1.5" backward offset shift stub. The tall turret body is specifically engineered for applications where standard turret heights create clearance issues--a common headache in truck and hot rod builds where the transmission tunnel, console, or seat placement demands flexibility the factory configuration cannot provide.

At its core, this is TREMEC's proven TKX platform--the slimmest 5-speed on the market, purpose-built for aftermarket applications from the ground up. The close-ratio 2.87 first gear paired with 0.68 overdrive fifth delivers the ideal balance of acceleration and highway cruising efficiency. All gears and shafts are manufactured from special-grade ASTM 4615 steel, while oversized gear widths and caged needle bearings in all positions ensure long-term durability. Multi-cone synchronizers with hybrid sintered bronze and carbon rings deliver smooth, crisp shifts even at the 7,500 RPM ceiling.

The end-loading case design isn't just about strength--though the ribbed three-piece aluminum housing delivers outstanding structural stiffness--it's about fitting where old-school 4-speeds used to live. The TKX slides into GM A-body tunnels (Chevelle, GTO, Cutlass, Nova, Camaro) without modification and uses the same GM Muncie bellhousing bolt pattern your existing hardware already fits. Dual speedometer outputs (mechanical 7-tooth cable drive plus analog electronic sensor) give you options for factory-style instrumentation or modern gauge clusters.

This configuration is not available through TREMEC--it's an MDL exclusive, modified at our Caldwell, Idaho facility. Fluid capacity is 2.7 quarts; TREMEC recommends HP-MTF, Dexron III, GM Synchromesh, Mobil 1 Synthetic ATF, or Pennzoil Synchromesh.

Description

Road course competitors and track day warriors demand a transmission that survives sustained high-RPM punishment while delivering predictable, consistent shifts lap after lap. This MDL-modified TREMEC TKX delivers exactly that - a 600 lb-ft torque capacity with the close-ratio gear spread that keeps your engine in its powerband through technical sections where momentum is everything.

The 2.87 first gear through 0.81 overdrive configuration eliminates the RPM gaps that kill corner exit speed. TREMEC's multi-cone synchronizers with sintered bronze and carbon hybrid rings enable clean, crisp shifts even under heavy braking and aggressive downshifts at competition speeds. The internal three-rail shift system with steel shift forks provides the mechanical precision serious drivers require.

MDL's custom shifter modification places the lever 2" left of center line with a 1" or 1.5" backward offset stub - precisely located for optimal ergonomics in race-prepped cockpits where every inch of shift throw matters. The ribbed three-piece aluminum housing with oversized gear widths and caged needle bearings delivers the structural rigidity and durability demanded by sustained high-load operation. All gears and shafts are machined from special-grade ASTM 4615 steel for maximum torque-carrying capacity.

Bellhousing Cover Plate | 1964-1981 Chevy SBC/BBC | 11-Inch 168-Tooth

Key Features

• Designed specifically for 168-tooth flywheels with 11-inch clutch bellhousing applications
• Protects ring gear and clutch area from dirt, debris, and road contamination
• Fits 1964-1981 Chevy small block and big block engines with standard Chevy bellhousing bolt pattern
• No transmission removal required for installation
• Lightweight stamped steel construction at just 17 ounces
• Direct replacement for worn or missing factory inspection covers

Description

A missing or damaged bellhousing cover leaves your flywheel and clutch exposed to constant contamination. Without proper protection, dirt, road grit, and debris work their way into the ring gear and clutch area over time, accelerating wear on friction surfaces and causing premature clutch failure. This cover plate eliminates that problem by sealing off the flywheel area while still allowing access for inspection when needed.

This cover is sized specifically for 11-inch bellhousings used with 168-tooth flywheels - the larger of the two GM flywheel sizes. The 168-tooth flywheel measures 14 inches in diameter and was commonly used in heavy-duty applications including trucks, police vehicles, and high-performance cars. These setups were typically paired with 11-inch clutches and require the larger bellhousing to clear the ring gear - and a correspondingly sized inspection cover.

Compatible with both small block and big block Chevy engines from 1964-1981 that use the standard 11-inch bellhousing configuration. Installation is straightforward and does not require transmission removal - simply bolt the cover in place using the included hardware. While the driveline will technically function without a cover installed, leaving the flywheel exposed to the elements is not recommended for any vehicle that sees regular use.

What's Included

• Stamped steel bellhousing cover plate
• Mounting hardware

Install Hardware Kit | LS and Late Model LT1/LT4 Engine to TKX | Aluminum Bellhousing

Key Features

• Complete bolt set for LS and late model LS-based LT1/LT4 engines with aluminum bellhousing to TKX
• 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.

What's Included

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

Key Features

• 24-pound lightweight billet steel construction - precision-machined from solid billet for strength without excess rotating mass

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.

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.

After decades of clutch dumps and hard stops, factory pedal pads crack, tear, and wear smooth--leaving you with exposed metal, a sloppy foothold, and an interior that looks neglected. This pedal pad kit restores proper grip and OEM appearance to manual transmission GM vehicles equipped with disc brakes.

The kit includes a 3" disc brake pedal pad and a 2" clutch pedal pad, both featuring the correct horizontal ribbed pattern that matches factory originals. The ribbing isn't just cosmetic--it provides the grip you need for precise pedal modulation, especially during spirited driving or heel-toe downshifts. The included stainless steel trim rings replicate the chrome OEM bezels, eliminating the unfinished look of exposed rubber edges and giving your pedal box that factory-fresh appearance.

Applications include 1967-81 Camaro and Firebird, 1964-72 Chevelle, 1968-79 Nova, 1971-75 Vega, and 1973-74 Ventura/Omega models with manual transmission and disc brake configurations. The pads mount directly to existing pedal assemblies--simply remove the old worn pads and press the replacements into place.

What's Included

• 3" disc brake pedal pad with horizontal rib pattern
• 2" clutch pedal pad with horizontal rib pattern
• Stainless steel trim rings (pair)

Key Features

• 3-inch manual brake pedal pad and 3-inch clutch pedal pad for full-size pedal applications
• Stainless steel trim rings deliver authentic OEM appearance
• Direct-fit replacement for 1972-1981 Camaro and Firebird F-body models
• Complete kit includes both pads and both trim rings in a single purchase

Description

Worn pedal pads and missing trim rings are telltale signs of a neglected interior - and on a manual transmission F-body, they're the two components your feet touch every time you drive. This complete pedal pad kit restores your 1972-1981 Camaro or Firebird pedal assembly to factory-correct condition with properly sized pads and polished stainless steel trim rings that replicate the original GM look.

The kit includes 3-inch diameter pads for both the manual brake pedal and the clutch pedal. This sizing is critical: 1972 models and certain other F-body applications used full-size 3-inch clutch pedals, while later models often featured narrower 2-inch clutch pads. If your clutch pedal arm accepts a 3-inch pad, this is the correct kit. The stainless steel trim rings add the finishing touch that separates a quality restoration from a parts-bin build - bright polished rings that frame each pad and resist corrosion far better than chrome-plated alternatives.

Installation is straightforward - the pads and trim rings are designed to fit the factory pedal arm mounting points without modification. Whether you're completing a frame-off restoration or just refreshing a driver-quality second-gen, this kit gives your pedal box the detail-correct appearance that factory manuals specified.

What's Included

• 3-inch manual brake pedal pad
• 3-inch clutch pedal pad
• Stainless steel trim ring (qty. 2)

Description

Converting your 1964-1966 Chevelle or GM A-body to hydraulic clutch actuation eliminates the adjustment headaches and heavy pedal effort that come with worn mechanical linkage. The LF Series Master Cylinder Kit delivers a complete retrofit solution engineered specifically for these chassis, removing the guesswork of sourcing components and figuring out mounting strategies.

The LF Series features a revolutionary design that solves the problems caused by direct-mount master cylinders. The common approach of bolting a 3/4" or 7/8" bore by 1" stroke cylinder directly to the pedal results in improper pedal pressure, excessive firewall loading, and poor modulation. MDL's mechanical linkage design provides mechanical advantage, reducing pedal pressure while allowing full pedal stroke to maximize clutch control. The linkage positions the cylinder perpendicular to the firewall for optimal force distribution and allows use of the factory clutch rod hole for a cleaner installation.

The 0.750" bore paired with a 1.2" stroke generates the precise fluid volume needed for modern hydraulic slave systems while maintaining light pedal effort. The firewall support bracket not only prevents flex under load but sets the master cylinder at the correct angle for proper pedal stroke and feel. The black plastic remote reservoir mounts separately on the firewall, keeping brake fluid away from the cylinder and simplifying installation.

This kit works with factory clutch pedals and most aftermarket OE reproduction pedals. Requires factory components to be in good working order - any modifications or damage to the firewall, pedal, or pedal hanger will affect master cylinder performance. Compatible with 1964-1966 Chevelle, Malibu, Monte Carlo, Tempest, LeMans, GTO, Grand Am, Grand Prix, Cutlass, Skylark, Century, and Regal. Made in the USA.

Description

Converting your '64-'66 Chevelle or GM A-body from mechanical linkage to hydraulic clutch operation raises immediate questions: Which master cylinder fits? How do you connect it to the pedal? Will you get enough pedal stroke to fully release the clutch? The LF Series Master Cylinder Kit answers all of them with engineered components designed specifically for this application--whether you're swapping in a TREMEC 5- or 6-speed or simply eliminating a worn-out Z-bar setup.

The heart of the system is a 0.750" bore master cylinder with a 1.2" stroke. This long-stroke, small-bore design generates the fluid volume needed to operate most aftermarket internal hydraulic release bearings or external slave cylinders while keeping pedal effort light and firewall loading minimal. The included firewall mounting bracket does more than provide structural support--it positions the master cylinder at the precise angle necessary to achieve proper pedal geometry and consistent feel throughout the stroke. By retaining the stock clutch pedal pivot point, the kit preserves the familiar pedal travel and effort drivers expect.

A black billet aluminum remote reservoir eliminates the need for additional firewall penetrations and keeps fluid access clean and convenient. Each kit ships complete with hydraulic lines, all mounting hardware, comprehensive installation instructions, and MDL's unique One-Man-Bleeder Kit so you can purge air from the system without recruiting a helper.

Description

Converting your '64-'66 Chevelle or GM A-body to hydraulic clutch actuation eliminates the headaches of worn Z-bar linkage, heavy pedal effort, and inconsistent engagement. The MDL LF Series Master Cylinder Kit provides a complete, engineered solution that maintains your stock pedal geometry while delivering the smooth, progressive clutch feel modern hydraulics provide.

The 0.750" bore master cylinder with 1.2" stroke produces 0.530 cubic inches of fluid displacement per stroke - enough volume to actuate most aftermarket external slave cylinders and internal hydraulic release bearings while keeping pedal effort light. The small-bore, long-stroke design generates maximum fluid volume with minimal firewall loading, so you get full clutch release without flex or fatigue at the mounting point.

The kit's firewall bracket serves two purposes: it distributes mounting loads across a reinforced area of the firewall, and it positions the master cylinder at the correct angle to utilize the full pedal arc. This geometry optimization means you get complete clutch release at the bottom of the stroke without the pedal bottoming out. The direct pedal mounting system uses your existing clutch rod hole where possible, preserving stock appearance and maintaining the factory pivot point.

The silver billet aluminum remote reservoir mounts away from the firewall for clean underhood aesthetics and easy fluid level inspection. Each kit includes MDL's proprietary One-Man-Bleeder Kit and comprehensive installation instructions. Works with stock clutch pedals and OE reproduction pedals. Requires DOT 3 or DOT 4 brake fluid.

The slip-on design mounts directly over the stock TREMEC bearing retainer - no replacement retainer required, no case modifications needed.

Tilton's engineering centers on precision and reliability. The billet aluminum body and piston are precision-machined in-house at Tilton, then treated with a durable, low-friction coating for long-wearing performance. The stainless steel threaded sleeve provides nearly 1.25 in. of height adjustability, allowing the bearing to be set anywhere from 1.77 in. to 3.00 in. to accommodate virtually any clutch setup. The 0.7 in. of piston travel provides complete clutch release, and the high-temperature mono-seal design with quad tensioner ensures positive sealing under demanding conditions.

The constant-contact design self-adjusts for clutch wear, maintaining the same pedal feel throughout the clutch's life without the need for periodic adjustment. Unlike traditional throwout bearings that require a gap and return springs, this sealed bearing stays in light contact with the pressure plate fingers at all times. The flat-face bearing features a 1.71 in. to 3.03 in. contact diameter that works with most 8.5 in. to 11 in. bent-finger and lever-type clutches. Compatibility extends to most bellhousings - while external slaves require application-specific bells, this internal design opens up options including original 4-speed bells and big-block bells.

This is a complete kit with everything needed for installation. Pair with an MDL LF Series master cylinder and appropriate steel-braided supply line (24 in. recommended for most applications) for a fully integrated hydraulic clutch system.

Description

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

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

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

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.

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.

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

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

Non-console Chevelles use a retaining ring to secure the rubber shifter boot to the floor hump - without it, the boot won't seal properly and you're left with dirt, moisture, and exhaust fumes entering the cabin around the shifter opening. This reproduction lower shifter boot ring replaces the original factory component that's often missing or damaged on restoration projects.

The retaining ring mounts under the carpet and creates the foundation for a proper boot installation. The ring seals the rubber boot to the floor, preventing debris and road noise from entering through the shifter opening. This is the same mounting system GM used on original non-console applications - the ring secures to the floor hump, carpet fits over top, and the boot assembly completes the seal at the shifter.

Designed specifically for 1964-1967 Chevelle applications without a center console, this retaining ring works with standard rubber shifter boots to complete the lower sealing system. The included mounting hardware means you have everything needed for installation without hunting for fasteners.

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

• 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

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

Description

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

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

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

What's Included

• One (1) retaining clip for Ford driven speedometer gear

Key Features

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

Description

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

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

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

What's Included

• 16-pulse digital speedometer sensor with three-pin connector

Description

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.
