ACT 2006 Chevrolet SSR Sport/Race Sprung 6 Pad Clutch Kit
ACT CA1-SPG6 is a complete Sport pressure plate, 6-pad sprung race disc and XACT Prolite flywheel kit for the Chevrolet SSR with the 6.0L LS2 and Tremec T56 six-speed manual. SSR owners usually land here after adding a supercharger, cam or nitrous and finding the stock clutch slips on the top end, or after a worn factory clutch starts chattering and the flywheel needs replacing anyway. ACT rates this kit at 830 ft-lb of torque capacity, 67 percent more than the original.
The SSR shares its LS2 clutch layout with the Cadillac CTS-V, and ACT builds this kit for both. The ACT Sport pressure plate uses ACT's own diaphragm design to raise clamp load and reduce deflection, with a four-stage heat treatment on every diaphragm. The 280 mm (11 in) disc is a 6-pad ceramic race disc with a sprung center. The springs damp torsional vibration so the driveline is not hammered on every shift, but engagement is still harsher than an organic street disc, with faster shifts as the payoff. ACT describes the feel as light to moderate pedal effort with aggressive engagement and OE to mild gear rattle, and recommends it for high horsepower street or race use.
The kit comes as a matched set: 600585 XACT Prolite flywheel, GM015S Sport pressure plate, 6280320 6-pad sprung race disc, 871013 release bearing spacer and ATGM026 alignment tool. ACT says the kit must be used with the ACT flywheel. Every ACT clutch is clamp-load tested and computer spin balanced to within .25 oz-in.
First rule out the hydraulics. A failing slave cylinder or air in the clutch line causes poor release and grinding that feel like a bad clutch. Then make a high-gear pull from low rpm and watch for the tach jumping ahead of road speed. Our slipping diagnosis guide covers the test, and the clutch chatter guide helps separate a worn disc from mount or oil-contamination problems.
Our listing is titled for the 2006 Chevrolet SSR. ACT lists CA1-SPG6 for the 2005-2006 Chevrolet SSR 6.0L LS2, the 2004-2005 Cadillac CTS-V 5.7L LS6 and the 2006-2007 CTS-V 6.0L LS2. The SSR offered the T56 manual only with the LS2 in 2005 and 2006; the 2003-2004 SSR with the 5.3L was automatic only, so this kit does not apply there. The input shaft spline is 1.125 in. If your SSR has had a transmission swap, send us your year and VIN plus the transmission details so we can confirm. More parts are in our rebuild kits category.

ACT lists the kit for the 2005-2006 SSR with the 6.0L LS2. Our listing title names 2006, so send us your VIN if you have a 2005 and want us to double-check. The 2003-2004 5.3L SSR was automatic only.
ACT rates CA1-SPG6 at 830 ft-lb measured at the crank, 67 percent over the original clutch.
ACT describes the Sport pressure plate as light to moderate pedal effort. Engagement is aggressive because of the 6-pad ceramic disc.
No. The kit includes a release bearing spacer, not a release bearing. Inspect the hydraulic release bearing and slave cylinder and replace them if they leak or are high mileage.
ACT says its race discs usually need only a few hard slips to lap in the surfaces. Avoid overheating the clutch in the first drives.
