The ACT HC12-HDSS Heavy Duty Performance Street Sprung Clutch Kit pairs ACT's most popular Heavy Duty pressure plate with its most popular street disc, and includes an ACT XACT Streetlite flywheel since only an ACT flywheel can be used with this kit. ACT's exclusive diaphragm design increases clamp load and reduces deflection, and 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.
