What is the main difference between this race disc and a standard clutch disc?

The 4-pad spring-centered race disc is designed for harsher engagement and faster shifting compared to a standard disc. It also uses a spring-center to properly damp torsional vibrations for quieter operation and increased reliability under demanding conditions.

Does this clutch kit include the necessary hardware for installation?

This kit includes the ACT Heavy Duty Pressure Plate and the ACT 4-Pad Spring-Centered Race Disc. It is recommended to consult the manufacturer's installation instructions for a complete list of required components and hardware.

What is the benefit of the heat-treating process for the diaphragms?

All diaphragms in ACT Heavy Duty pressure plates undergo a four-stage, heat-treating process. This process is done to improve performance and ensure the diaphragm can withstand the increased clamp load and reduce deflection over its lifespan.

Product Details

HD/Race Sprung 4 Pad

BM17-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.
