The Centerforce(R) DYAD DS 10.4" twin disc clutch has been developed for vehicles requiring a holding capacity of 500 to 1300 ft/lbs of torque at the crank. The pressure plate features our patented centrifugal weight system for superior clamp load over stock and our patented ball bearing actuated pressure plate providing light pedal effort. The discs are equipped with organic segmented facings providing increased holding capacity and the sprung/dampened drive disc provides smooth drivability. DYAD DS clutches are equipped with a lightened billet steel flywheel providing low inertia resulting in quicker RPM's. Components are designed, machined and assembled in the USA. DYAD DS clutches are match balanced and ready for installation using the included ARP fasteners.
