ACT Twin Disc HD Street Clutch Kit, 1997-2015 Chevrolet Camaro/Corvette & Pontiac Firebird/GTO | T1S-G05

The T1S-G05 is a twin disc HD street clutch kit built for LS-swapped and factory LS-powered GM platforms. Doubling the friction surface area versus a single-disc setup improves heat capacity, wear life, and torque handling. A proprietary Positive Lift Floater System keeps operation quiet with no floater rattle and no posts to wear, and every diaphragm undergoes ACT's exclusive four-stage heat-treating process. The kit ships with a CNC-machined, dynamically balanced flywheel plus pressure plate, two discs, floater, and alignment tool for a complete installation. Some kits may include a pilot bearing and release bearing.
