We have introduced a new C6 Corvette flywheel that will allow 2005-2011 LS2, LS3 and LS7 equipped Corvette owners to use the new factory dual disk ZR1 Corvette clutch assembly. The flywheel is a direct bolt in replacement but does require the use of the factory ZR1 clutch assembly. It is made from billet steel, manufactured by the OEM supplier of the original ZR1 flywheel and has been tested in excess of 12,000 RPM to its integrity.

The ZR1 clutch requires this new steel flywheel that has six bolt holes as opposed to nine on the ZR1. This allows the flywheel to be bolted to the crankshaft on any C6 Corvette including the Z06. The steel flywheel, also sold separately, is made from billet steel by the original ZR1 flywheel manufacturer and has been tested in excess of 12,000 rpm. This flywheel is only compatible with the ZR1 Corvette clutch assembly.

If you are tired of your Corvette’s clutch slipping, or on the flip side you can’t enjoy driving your Corvette because it seems that the clutch has an on/off switch, consider our new clutch assembly. With a bolt on installation, all necessary components and hardware your Corvette will be capable of holding huge amounts of horsepower while maintaining a smooth ride.

Tested at over 700 Horsepower!

The Stock flywheel will NOT accept the ZR1 Twin Disc clutch.

The ZR1 flywheel is 9 Bolt where the LS3 is 6 bolt, this requires a special Flywheel to mate up the ZR1 Twin disc Clutch to the LS3, Plus a Spacer to put behind the ZR1 Slave Cylinder and longer bolts.
  • For all LS engines (excluding LS9 and LSA)
  • Aluminum flywheel with 6 bolt pattern for standard LS engines
  • Flywheel weighs 12.0lbs.
  • For do-it-yourself kit construction of LS9X or LS9R clutch kits

"These Clutches are The BEST I have Ever Driven and Can take a Lot of Punishment after the Break in Period. Remember guys Proper Break In is Critical to ANY Clutch."
