ACT SB5-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit for Subaru Legacy and Forester

SB5-HDG6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty 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 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure 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 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. HD/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT SB5-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit is engineered for high-horsepower street and race applications requiring increased clamping force, rapid shifting, and dependable heat resistance. The kit features ACT’s Heavy Duty pressure plate with an exclusive diaphragm design that increases clamp load, reduces deflection, and helps maximize clutch service life. Each diaphragm undergoes a four-stage heat-treating process, while precision cover stampings provide the rigidity and consistency needed for reliable performance.

The included 6-pad, spring-centered race disc uses select ceramic friction materials for high heat tolerance and aggressive power transfer. Its spring-centered design helps damp torsional vibrations and resist failure under demanding conditions. Wraparound spring windows and thicker spring retainer stampings improve support, reduce stress concentrations, and increase strength. Engagement is more aggressive than an OE-style clutch, with light to moderate pedal effort, faster shifting, and possible mild gear rattle. The disc is recommended for larger clutch applications where additional heat absorption is required.
