Powergrip HD Clutch Set GM 11in x 1-1/8-26

The Powergrip HD Clutch Set GM 11in x 1-1/8-26 from RAM CLUTCH is purpose-built for General Motors vehicles that demand serious holding power and reliability. Whether you're running a stock engine, a moderately modified street machine, or preparing for weekend track duty, this clutch assembly delivers the clamping force and thermal stability that serious drivers expect. The 11-inch diameter with 1-1/8-26 spline configuration is engineered to handle daily driving while maintaining the engagement characteristics and pedal feel that manual transmission enthusiasts prefer.

RAM CLUTCH's HD designation indicates a reinforced pressure plate and heavy-duty friction material composition designed to withstand elevated torque loads without glazing or premature wear. The pressure plate uses improved clamping geometry and heat-treated steel components to maintain consistent clamp load across extended driving cycles, preventing clutch fade and chatter. The friction disc features organic or semi-metallic material depending on configuration, providing a balance between smooth modulation and aggressive holding capacity—critical for both street manners and performance applications where slip cannot be tolerated.

This clutch set fits Gen II, Gen III, and early Gen IV GM small-block and LS platforms, as well as certain mid-size trucks and performance vehicles equipped with T56, T56 Super Magnum, or Tremec transmissions. Installation requires flywheel resurfacing and proper pilot bearing alignment to ensure concentricity and eliminate vibration. Experienced mechanics should verify year, engine code, and transmission compatibility before ordering; improper fitment can result in engagement issues and accelerated wear. At 26.8 lbs, the assembly is substantial enough for thermal mass while remaining light enough for responsive throttle response in tuned applications.
