    ACT Heavy Duty Clutch Kit 4 Puck Sprung Disc for 04-21 Subaru STI, 07-09 Legacy GT Spec B

    The SB10-HDG4 kit features ACT's most popular Heavy Duty pressure plate, designed to enhance performance and durability. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. These pressure plates are precision-engineered with rigid cover stampings and undergo a four-stage heat-treating process to ensure unparalleled reliability and consistency.

    Paired with ACT's 4-pad spring-centered race disc, this kit offers spring-centered construction to dampen torsional vibrations for quieter operation while resisting failure under harsh conditions. The race disc's wraparound spring windows and thicker retainer stampings enhance support, reduce stress, and improve strength. With a 4-pad design, engagement is harsher, but shifting becomes faster, making it ideal for smaller engines and compact disc sizes. Additionally, the Monoloc system, crafted from hardened Chrome-moly steel, replaces the standard two-piece wedge collar, ensuring uniform loading and proper alignment for consistent performance, even with vehicle modifications.

    Engineered for performance and reliability, the SB10-HDG4 kit delivers optimal results under demanding conditions, offering drivers confidence and long-lasting durability.
