The ACT ZM2-HDSS Heavy Duty Performance Street Sprung Clutch Kit pairs ACT's most popular Heavy Duty pressure plate with its most popular street disc. ACT's exclusive diaphragm design increases clamp load and reduces deflection, and every diaphragm goes through a four-stage heat-treating process. The Performance Street disc uses premium organic material with high copper content for better heat transfer and a steel-backed lining for greater burst strength, with reduced marcel for faster shift action.
