The XTD dual multi friction disc system distributes pressure plate clamping force evenly over a 360-degree friction-facing on one side of the clutch disc, while the opposing side uses a segmented friction-facing to maximize clamping pressure and increase clutch holding-capacity. This combination of dual configured friction-facings, coupled with HD pressure pate, creates the ultimate clutch system that is engineered to shift smooth and extend clutch life, while providing best in class XTD grip.Multi Friction is engineered for those who are looking for the ultimate in street/strip holding power and performance without sacrificing pedal effort and driver control. While the Multi Friction has been engineered primarily as a street clutch it can be used in mild competition applications. XTD specifically designed high torque disc delivers maximum holding capacity without compromise. The sprung retainer assembly boasts heat treated 6 dual springs and severe duty retainer rivets, ensuring power and reliability. The XTD pressure plate features special single diaphragm design to increase clamp load. It features induction hardened diaphragm, CNC machined castings, stronger drive straps and rivets. XTD Racing pressure plate provides smooth and precise feel with easy modulation
