Advanced Clutch HD Race Sprung Clutch Kit - HC12-HDG4

The 10th Generation Civic Type R is the ultimate Honda-lovers goal. Already responsive and powerful as delivered, this latest platform is being explored for serious transformations in power output. As those improvements surpass the capabilities of the OE clutch components, ACT is again stepping up to provide the latest clutch developments - just as Honda drivers have counted on for over two decades.

HC12-HDG4 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 4-pad spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even 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 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.

Please Note: Must use ACT flywheel (included in kit). Flywheel bolts included (M12-1.0 x 25mm). Pressure plate bolts included (M8-1.25 x 16mm).
