4 Inch twin disc clutch has been developed for vehicles requiring a holding capacity of 700 to 1600 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 metallic paddle/button style friction material providing increased holding capacity. DYAD XDS clutches are equipped with a lightened billet steel flywheel providing low inertia resulting in quicker RPM's.

Due to the aggressive nature of this race inspired clutch, vehicles may experience some floater noise and/or chatter during operation. Components are designed, machined and assembled in the USA.

DYAD XDS clutches are match balanced and ready for installation using the included ARP fasteners.
