Show original supplier description
The Mantic Twin Disc Clutch, part number M921201-B, is a ceremetallic clutch system engineered as a premium upgrade for C5 Corvettes. Constructed entirely from billet materials, this clutch offers superior durability and resistance to flexing at high RPMs compared to stamped steel units. It features dual 9-inch ceremetallic discs for efficient power transfer and a lightened steel flywheel weighing 16 lbs, which allows for quicker engine revving. The clutch is rated for 1010 ft-lbs of torque at the crank and 820-850 ft-lbs at the wheels, though actual capacity may vary with driving style and power levels. The kit includes a lightened steel flywheel, the twin-disc clutch with sprung centers and cushioned discs, a new OE hydraulic release bearing, new flywheel and clutch bolts, all necessary hardware, and an HD aluminum clutch case. This Mantic clutch system is SFI Approved 1.1 and is completely rebuildable, offering a long-term solution for worn clutch components. The application is for 1997-2004 C5 Corvettes with either the 5.7L LS1 or 5.7L LS6 engines.
