Stage Five
SPEC's strongest clutch is made specifically for drag racing high powered vehicles or applications that call for a "slipper" clutch/progressive torque-induced engagement. They feature an unsprung, rigid, iron disc that engages instantly and strongly. The kit comes with a high clamp pressure plate, iron disc assembly with install tool. This applicaiton does not utilize a conventional throwout bearing, as the releaser is a concentric hydraulic slave/bearing assembly. This concentric slave is available as an option to the kit.
This clutch kit is designed for use with the factory flywheel or an aftermarket flywheel modeled after the factory wheel, which has a recessed friction surface. For SPEC non-ratcheting clutch and flat flywheel packages, see kit numbers SC661-SC665. These kits increase friction surface diameter to 12 inches while reducing rotating mass by up to 36%. The flywheel package includes race bolt kit.
