Description
The MDL Superior 10.5" GM Clutch Kit delivers the street-friendly engagement characteristics and proven durability that performance builders demand. Designed for classic GM applications using hydraulic clutch actuation systems, this kit pairs a diaphragm-style pressure plate with steel-backed organic friction material for the ideal balance of smooth pedal feel and reliable torque transfer up to 275 ft-lb.
The steel backing on the organic facings prevents disc warping under heat cycles while the organic compound delivers progressive, chatter-free engagement that makes daily driving enjoyable. The sprung hub design further isolates drivetrain vibration, eliminating the harshness that plagues solid-hub racing discs. The 10-spline, 1-1/8" disc mates to early GM transmissions and select TREMEC conversion applications that specify a 10-spline input shaft. [VERIFY: Original listing mentions 26-spline input shaft compatibility in features - confirm whether this kit is designed for transmissions with 26-spline input or 10-spline input]
The diaphragm pressure plate eliminates the adjustment requirements of older three-finger designs while providing consistent clamping pressure across the full disc surface. Each kit ships with both GM and BOP (Buick/Oldsmobile/Pontiac) pilot bushings to accommodate different crankshaft configurations, plus a precision alignment tool for proper installation. Compatible with 11-5/8" bolt circle flywheels.
Every Superior Series clutch is hand-assembled at MDL's Caldwell, Idaho facility and undergoes a comprehensive quality inspection before packaging. Backed by a 1-year free-from-defect warranty and lifetime technical support. Made in the USA.
