The HS1-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular street disc. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life; every diaphragm goes through a four-stage heat-treating process, and cover stampings are precision-made for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for better heat transfer, plus a steel-backed lining for greater burst strength and durability. Reduced marcel gives faster shift action while keeping engagement smooth and reliable for daily driving.
