The Centerforce(R) DYAD DS 8.75" twin disc clutch has been developed for vehicles requiring a holding capacity of 300 to 600 ft/lbs of torque at the crank. The billet pressure plate features our patented centrifugal weight system (where applicable) for superior clamp load over stock and our patented ball bearing actuated pressure plate (where applicable) providing light pedal effort. The discs pack is equipped with Kevlar full facing material providing increased holding capacity and is available in either sprung or solid hub (possible gear noise) depending on the application. DYAD DS clutches are equipped with a lightened billet steel flywheel providing low inertia resulting in quicker RPM's. Vehicles may experience some floater noise during operation. Components are designed, machined and assembled in the USA. DYAD DS clutches are match balanced and ready for installation using the included ARP fasteners.
