The ACT clutch kit includes a Sport pressure plate, 4-pad, spring-centered race disc, release bearing, pilot bearing and alignment tool. The Sport pressure plate allows for a 20 to 40 Percent increase in clamp load over the stock unit. ACT’s Sport pressure plates have a pedal feel that is stock to moderate and are recommended for use with a street disc. ACT pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency, and some are reinforced to reduce flex and improve efficiency and the feel of the pressure plate. ACT pressure plates are manufactured from new units not rebuilt from worn out parts and are 100 Percent tested and computer balanced for smooth operation at high RPM. ACT’s 4-pad, spring-centered race disc features a spring-center construction to properly dampen 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. The heavy duty torsional dampening springs are stronger in most cases than standard springs and are provided in the best sizes and spring rates to suit the application. 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 the smaller disc sizes in smaller engines. All ACT race discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification. The kit is completed with a quality, stock replacement release bearing, pilot bearing and alignment tool.
