The Katech LS9 aluminum flywheel is your answer to any C6 Corvette clutch woes. The aluminum flywheel is designed to fit LS2, LS3 & LS7 models using the factory 6-hole bolt pattern. When combined with a factory ZR1 twin disk clutch assembly your Corvette can handle over 700 rear wheel horsepower and still be dependable and drivable as your stock C6 Corvette clutch. You no longer need to made do with poor drivability so that you can handle more power, now you can get the best of both worlds. The LS9 flywheel is 8lbs lighter then the stock Z06/LS7 clutch.

Note: Fits all 2005-2013 Corvettes including standard, Z06, and Grand Sport models. Will not fit 2009-2013 ZR1 Corvettes due to change in flywheel mounting.
