ACT HD/Race Sprung 4 Pad Clutch Kit (Z64-HDG4)

The Z64-HDG4 kit combines ACT's Heavy Duty pressure plate with a 4-pad spring-centered race disc, delivering a powerful and durable clutch solution for high-performance applications. The Heavy Duty pressure plate is designed with an exclusive diaphragm that enhances clamp load, minimizes deflection, and extends clutch life. Every diaphragm undergoes a meticulous four-stage heat-treating process to ensure superior performance and reliability. Precision cover stampings provide added rigidity and operational consistency. The 4-pad spring-centered race disc is engineered for both strength and smooth operation.
