XClutch 05-07 Chevrolet Corvette Base 6.0L Stage 2 Cushioned Ceramic Clutch Kit
A 2005-2007 C6 Corvette with the 6.0L LS2 makes 400 lb-ft from the factory, and once it gets a cam, headers or a tune the original clutch is often the first thing to give up: the tach climbs in 3rd or 4th at wide open throttle while the car stops pulling. The XClutch XKCR28692-1C is a complete Stage 2 upgrade for that car. It combines a heavy duty diaphragm pressure plate, an 11 in cushioned ceramic disc, a chromoly flywheel and a hydraulic release bearing in one box, so the whole clutch stack is replaced at once.
The base C6 runs a T56 six-speed manual mounted at the rear axle, with a torque tube connecting it to the clutch housing behind the engine. The clutch itself lives up front at the bellhousing, and release is handled by a concentric hydraulic bearing rather than a fork. XClutch rates this kit at 780 ft-lb of torque capacity (a figure that includes their factor of safety) with 40 percent more clamping force than stock. The disc is ceramic for heat capacity, but unlike a rigid puck disc it uses a sprung hub plus cushioning between the friction faces, which XClutch says gives better pedal modulation. XClutch positions it for performance street use where high heat capacity is needed, not for a stock car that just needs a fresh clutch.
Run a controlled pull in 4th from low rpm and watch whether the tach outruns the speedometer. If it does, rule out the hydraulics: a weak master cylinder, air in the line or a failing concentric bearing can keep the clutch from fully clamping or releasing. Oil from a rear main seal on the disc will also cause slip, and a new clutch will slip again if that leak is not fixed. Our slipping diagnosis guide and flare vs. slip guide help separate a clutch problem from other drivetrain faults.
This listing fits the 2005, 2006 and 2007 Chevrolet Corvette Base with the 6.0L V8 and six-speed manual. XClutch lists a 26-spline input with a 1 9/64 in shaft diameter. It is not listed for the Z06 or for 2008-up cars, which moved to the 6.2L engine and a different manual gearbox. If your car has been swapped or you are not sure what is in it, send us the year and VIN before ordering and we will confirm. A Stage 3 option covering a wider C6 range is the Spec Stage 3 kit, and for big-power builds there is the Clutch Masters 850 twin disc.

No. It is listed for the 2005-2007 Corvette Base with the 6.0L LS2 and six-speed manual only. The Z06 and 2008-up cars use different clutch parts.
Per XClutch: pressure plate, Stage 2 cushioned ceramic disc, chromoly flywheel, hydraulic release bearing, pilot bearing, pressure plate bolts and an alignment tool.
XClutch rates it at 780 ft-lb including its factor of safety, with 40 percent more clamp force than stock.
It engages quicker than an organic disc, but this is the cushioned version with a sprung hub, which XClutch built for better pedal modulation in performance street cars.
Use the DOT brake fluid specified on your reservoir cap and bleed until the pedal is firm and returns fully.
It can be. XClutch notes single mass flywheel conversions may add gearbox rattle at idle, which is a normal trait of the setup.
