Each clutch comes with a matched pressure plate and a heavy duty, high torque steel-back clutch disc. The riveted clutch disc with advanced steel-back friction material provides additional clamping force and superior durability. A reinforced steel backing allows for better heat dissipation delivering extended wear and quick recovery. An 8-spring hub with encapsulated damper springs and a sintered metallic friction surface can handle three times the shock load versus a standard coil spring. Sintered metallic material provides a degree of slippage on vehicle launch to provide a smooth engagement. All Hays 650 Clutches come in a kit complete with pressure plate, clutch disc, throwout bearing, alignment tool, and instructions.
