This newly developed asbestos free friction facing is used, which has high heat resistance and high burst strength characteristics. No steel back is required which can cause high RPM ?lockout? and/or synchro damage. Superior in shift operations and half-engagement feel, this clutch disc is recommended for any sports/performance use. The clutch covers are designed to achieve a clamping load that is approximately 40% higher than the OEM part allowing a higher torque transmitting capacity. Ductile material is used for all pressure plates and high burst strength can be achieved in all temperature ranges.
