ACT SB12-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit for Select Subaru 2005-2025

Fits select 2005-2025 Subaru Baja, Forester, Impreza WRX, Legacy, Outback, and WRX models.

The ACT SB12-HDG6 Heavy Duty Race clutch kit is engineered for high-performance applications where faster shifting and increased torque capacity are required. This kit features the ACT Heavy Duty pressure plate, which utilizes an exclusive diaphragm design to increase clamp load and reduce deflection. Every diaphragm undergoes a specialized four-stage heat-treating process to ensure long-term durability and consistent performance, while precision cover stampings provide the rigidity necessary for aggressive use.

The 6-pad, spring-centered race disc is designed specifically to manage high heat levels and damp torsional vibrations, protecting your drivetrain under harsh conditions. To improve reliability, ACT uses wraparound spring windows and thicker retainer stampings to reduce stress concentrations and provide superior spring support. While engagement is significantly firmer than a standard street clutch, the race-oriented design allows for the rapid gear changes required in competitive driving.
