Product Description

Discover ACT 's top-selling Heavy Duty pressure plate, boasting advanced features for superior performance. Engineered with an exclusive diaphragm design, ACT's Heavy Duty pressure plates enhance clamp load, minimize deflection, and prolong clutch lifespan. Undergoing a rigorous four-stage heat-treating process, all diaphragms ensure unmatched durability. Precision cover stampings ensure consistency and rigidity, while ACT's 4-pad or 6-Pad rigid race discs feature premium ceramic friction materials for optimal performance. Crafted with a chrome-moly hub that's heat-treated for added strength, the lightweight design enables seamless, trouble-free shifts. Despite a slightly harsher engagement, the 4-pad or 6-pad rigid race disc ensures lightning-fast shifting, making it ideal for smaller engines with compact disc sizes.
