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

This ACT Xtreme clutch kit features a 4-pad race disc and an Xtreme pressure plate. This setup provides harsher engagement and faster shifting compared to a standard clutch, and the pressure plate offers increased clamp load for more demanding driving.

Does this clutch kit come with all the necessary hardware for installation?

The ACT Z64-XTG4 kit includes the Xtreme pressure plate and the 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 does the spring-centered design on the race disc do?

The spring-centered construction on the ACT race disc is designed to properly damp torsional vibrations. This helps to reduce noise during operation and also increases the disc's resistance to failure, even when subjected to harsh driving conditions.

Product Details

Z64-XTG4 kit features an Xtreme pressure plate for the most demanding driver. ACT Xtreme 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 construction 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.
