The kits feature ACT's most popular heavy-duty pressure plates—which use exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. All diaphragms endure a 4-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. The 6-pad, spring-centered race discs feature a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. Spring retainers utilize wraparound spring windows and thicker retainer stampings for spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc (recommended for larger clutch sizes to absorb more heat), engagement is harsher, but shifting is faster. Available in sprung or solid hub style.
