The 4-pad, spring-centered race discs from ACT are made with high quality, ceramic friction materials that produce 28 percent more torque and friction capacity over organic materials.
Properly dampening torsional vibrations for quieter operation, the spring-center construction resists failure even under harsh conditions.
Utilizing wraparound spring windows and thicker retainer stampings, ACT spring retainers provide spring support, reduce stress concentrations, and increase strength and reliability.
Stronger in most cases than standard springs, the heavy duty torsional dampening springs are provided in the best sizes and spring rates to suit the application.
Engagement with the 4-pad, spring-centered race disc is harsher, but shifting is faster.
Featuring a heat-treated spring steel drive plate, the 4-pad spring-centered race disc is well-suited for 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.
