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 reliability and strength.
In most cases, the heavy duty torsional dampening springs are stronger 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.
The race disc features a heat-treated spring steel drive plate and 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.
