Description
When you need hard-hitting bite for drag racing launches or quicker shifts for road racing, bronze friction material delivers where organic facings fall short. This MDL Superior clutch set addresses the specific problem of insufficient holding power when you can't increase pressure plate clamp load or step up to a larger diameter disk. Bronze facings provide a higher coefficient of friction than organic materials, allowing the same clamping force to bite harder and hold more power—rated at 675 lb-ft torque capacity in this 11" configuration.
The bronze material excels in racing applications because of how quickly it engages and its ability to handle extreme heat and abuse. MDL's bronze formulation includes iron pieces that actually create more friction as the material gets hotter—the opposite of fade-prone organic materials. The sprung hub design dampens driveline shock while maintaining aggressive engagement characteristics, protecting your drivetrain from the harsh impact of hard launches.
The 12-5/8" equidistant bolt pattern fits standard GM applications with 11" clutch sizes. The heavy-duty diaphragm pressure plate provides consistent clamping force across the entire friction surface and eliminates the over-center action problems common with three-finger designs. The 1-1/8" x 26-spline hub mates directly with GM transmissions equipped with 26-spline input shafts, including TKO, TKX, and Magnum configurations.
Every MDL Superior clutch is hand-assembled in-house to ensure quality and flawless operation, then checked and double-checked for accuracy before shipping—so you receive a ready-to-install premium piece backed by a 1-year defect warranty. Designed for mechanical throw-out bearing applications requiring serious holding power and aggressive engagement. Made in the USA.
