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

The 6-pad sprung race disc is designed for faster shifting and better damping of torsional vibrations. Engagement is harsher compared to a stock clutch, but it allows for quicker gear changes.

What makes the ACT Heavy Duty pressure plate different?

ACT's Heavy Duty pressure plates use an exclusive diaphragm design that increases clamping force, reduces deflection, and is heat-treated for longer life and consistent performance.

Does this clutch kit include everything needed for installation?

This kit includes the ACT Heavy Duty pressure plate and the 6-pad sprung race disc. It is recommended to consult the manufacturer's installation instructions for any additional hardware or components that may be required for proper installation.

Product Details

HD/Race Sprung 6 Pad

AA2-HDG6 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 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure 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 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat.
