ACT GM9-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit for Select Chevrolet and Pontiac 1997-2013

Fits select 1997-2013 Chevrolet Corvette, Camaro, Trailblazer SS, and Pontiac Firebird, GTO.

The ACT GM9-HDG6 Heavy Duty Race clutch kit is engineered for high-performance applications where rapid shifting and superior heat capacity are critical. This kit centers on ACT's Heavy Duty pressure plate, which utilizes an exclusive diaphragm design to increase clamp load and reduce deflection. Every diaphragm undergoes a specialized four-stage heat-treating process to ensure consistent pedal feel and long-term durability.

The included 6-pad spring-centered race disc is designed for larger clutch sizes and provides the thermal capacity needed for harsh conditions. While engagement is significantly firmer and harsher than a stock unit, the spring-centered hub effectively damps torsional vibrations to protect the drivetrain. The assembly is reinforced with wraparound spring windows and thicker retainer stampings to increase overall strength and reliability during high-RPM use.

• Increased Clamp Load: Heavy Duty pressure plate maximizes engagement force and clutch life.
• Race-Ready Performance: 6-pad metallic disc allows for faster shifting and higher heat absorption.
• Precision Engineering: Stamped steel covers provide the rigidity needed for consistent performance.
• Enhanced Durability: Heat-treated diaphragms and reinforced spring retainers resist failure under stress.
• Manufacturer Part Number: GM9-HDG6
