Description

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

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

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

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

Description

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

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

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

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

Description

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

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

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

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

Description

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

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

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

This twin-disc clutch handles up to 1,200 crank horsepower while maintaining a comfortable pedal feel that will not leave you massaging a charlie horse after a trip through downtown at rush hour.

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

McLeod's patent-pending large red adapter ring system eliminates the need for a dedicated flywheel. The ring mounts to your existing large-diameter flat-style flywheel (Chevy 168T and similar) and provides the proper mounting surface for the twin-disc assembly. This adapter ring approach reduces cost while maintaining strength. Note: This kit requires a flat-style flywheel with a crank relief of 6.250" or less for proper fitment - it will not work with recessed or stepped flywheels.

Description

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

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

Description

A worn or missing pilot bushing leads to input shaft misalignment, clutch drag, difficult shifting, and premature transmission wear. This Oilite bronze pilot bushing solves that problem by providing precise centering and support for your transmission's input shaft snout where it meets the crankshaft bore. When you depress the clutch, the pilot bushing allows the flywheel to continue spinning while the input shaft remains stationary--preventing metal-to-metal contact and protecting your drivetrain components.

Manufactured from premium-grade sintered bronze, this bushing is impregnated with oil lubricant that seeps to the surface during operation as temperature rises. This self-lubricating design eliminates the need for external grease and provides consistent lubrication throughout the bushing's service life. Unlike needle roller pilot bearings that can seize and destroy your input shaft when they fail, a bronze bushing's softer material sacrifices itself rather than damaging expensive transmission components.

Precision-machined to 1.094" OD x 0.670" ID x 0.500" width, this bushing delivers exact OEM fitment for Chevrolet Small Block V8, Big Block V8, and Gen III/IV LS-series engines including LS1, LS3, and LS6. The dimensions ensure proper press-fit into the crankshaft bore while maintaining correct clearance on the input shaft tip.

Pilot bushings are wear items and should be replaced with every clutch service--even if the old bushing appears fine. Pro tip: freeze the new bushing before installation to ease press-fit, and use bread packed into the bore to hydraulically remove the old bushing without the mess of grease.

Kit Includes

• One Oilite bronze pilot bushing (1.094" OD x 0.670" ID x 0.500" width)

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.

• 2-foot tubing length provides flexible positioning during bleeding procedures
• Syringe enables controlled fluid extraction or reverse-bleeding
• Rubber stopper creates airtight seal for various bleeding methods
• Compatible with all MDL master cylinders and reservoirs

Description

Air trapped in a hydraulic clutch system creates spongy pedal feel, inconsistent engagement, and frustrating shifts. Because air compresses under pressure while hydraulic fluid does not, even small air pockets rob the system of the firm, predictable response a performance clutch setup demands. This MDL Bleeder Kit provides the essential tools to purge air from your hydraulic clutch circuit and restore crisp, confident clutch operation.

The kit centers on a precision syringe paired with 2 feet of clear vinyl tubing sized to fit securely over standard bleeder nipples. The transparent tubing is critical for the job--it lets you visually confirm when fluid runs clear and bubble-free, so you know exactly when the system is fully bled. Whether you prefer gravity bleeding, pump-and-bleed with a helper, or the reverse-bleed method (pushing fresh fluid up from the slave cylinder into the reservoir), this kit handles all approaches.

The included rubber stopper seals off the reservoir or other openings as needed during the bleeding procedure, preventing air from re-entering the system while you work. Complete bleeding instructions are detailed in the documentation that accompanies every MDL hydraulic clutch kit, walking you through the step-by-step process for achieving firm pedal feel.

This kit works with all MDL master cylinders and reservoirs across Ford, GM, and Mopar applications. Keep one on hand for initial installation, routine fluid changes, or anytime pedal feel tells you air has crept into the system.

What's Included

• Reuseable Syringe for controlled fluid injection

Description

Shift knobs with painted or surface-applied graphics eventually fade, peel, and look worn out. This 6-speed black shift ball solves that problem with subsurface graphics that are embedded during manufacturing - the white shift pattern literally cannot wear off, no matter how many miles you put on it or how aggressively you shift.

The specially formulated high-impact polymer resin handles serious abuse. Unlike cheap plastic knobs that crack under temperature extremes or hard use, this material is engineered specifically for performance applications where torque loads and heat cycling push lesser materials past their limits. The 2-1/8" diameter strikes the right balance between palm-filling grip and nimble throws during spirited driving.

Designed with a universal 16mm x 1.5 internal thread, this shift ball works with Ford, GM/Chevy, and Mopar applications when paired with the appropriate thread reducer. Standard SAE sizes like 1/2"-20, 3/8"-16, and 7/16"-20, plus metric options from 8mm to 12mm, are all compatible with readily available brass thread adapters. If you're unsure what thread size is on your shift lever, MDL's tech team can help you identify the correct reducer - just call 208-453-9800.

Built in the USA by a manufacturer that has been shifting gears since 1952, this shift ball delivers the quality, precision, and durability that OEM, aftermarket, and custom builders have relied on for over seven decades.

What's Included

Description

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

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

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

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

Description

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

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

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

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

Description

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

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

Description

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 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
