The ACT GM12-HDSS kit features ACT's most popular Heavy Duty pressure plate paired with its most popular street disc for the Chevrolet Camaro SS/Z/28 and Corvette Z06. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life, with every diaphragm undergoing ACT's four-stage heat-treating process. Precision cover stampings add rigidity and consistency. The included Performance street disc uses premium organic friction material with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action and increased strength and reliability.
