ACT HC12-HDG6 Heavy Duty 6-Pad Sprung Clutch Kit for Honda Civic Type R and Acura Integra Type S

HC12-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 HC12-HDG6 Heavy Duty clutch kit is engineered for high-performance street and race applications requiring increased clamp load, fast shifting, and dependable operation under demanding conditions. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad, spring-centered race disc designed to handle elevated heat and aggressive driving while maintaining torsional vibration control.

The ACT Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and help maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for consistent performance, while precision cover stampings improve rigidity and stability. The pressure plate is 100% clamp-load tested and dynamically computer balanced for smooth, reliable operation at high engine speeds.

The 6-pad, spring-centered disc uses select ceramic friction materials for high-temperature performance and features reinforced spring retainers with wraparound spring windows. These components provide improved spring support, reduce stress concentrations, and increase strength and reliability. Engagement is more aggressive than an original-equipment clutch, with faster shifting and light to moderate pedal effort. Mild gear rattle may occur, and friction life is moderate depending on vehicle use and driving conditions. The kit is recommended for larger clutch applications, high-horsepower street vehicles, and race use. It is designed for the 2017-2021 and 2023-2025 Honda Civic, including Civic Type R applications where specified, as well as the 2024-2025 Acura Integra Type S. ACT backs this performance clutch kit with its one-year industry warranty.
