Advanced Clutch GM12-HDSS Heavy-Duty Performance Street Sprung Clutch Kit

The Advanced Clutch GM12-HDSS Heavy-Duty Performance Street Sprung Clutch Kit combines a heavy-duty pressure plate with a performance street disc for reliable clutch operation and increased torque capacity. The kit is rated for 709 lb-ft of torque, providing a 42% increase over original equipment capacity.

The heavy-duty pressure plate uses an exclusive diaphragm design intended to increase clamp load, reduce deflection, and maximize clutch life. Its diaphragm undergoes a four-stage heat-treating process, while the precision cover stamping supports rigidity and consistency during operation.

The sprung street disc uses premium organic friction material with high copper content for improved heat transfer, along with steel-backed lining for increased burst strength and durability. Reduced marcel supports faster shift action, while the sprung disc design complements the pressure plate for performance street use.

This kit includes an ACT Prolite flywheel, alignment tool, and grease. The application must use the included ACT flywheel or an LS Flat flywheel. The kit does not include a pilot bushing, release bearing, pressure plate bolts, clutch slave cylinder, or flywheel bolts.
