The ACT BM14-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with its most popular street disc. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life, with precision cover stampings for rigidity and consistency. The Performance Street disc features premium organic friction material with high copper content for better heat transfer, plus steel-backed lining for greater burst strength and durability. Reduced marcel gives faster shift action to complement the ACT pressure plate, with increased strength and reliability.
