ACT Heavy Duty Sprung 6-Puck Disc Clutch 1998-2023 Impreza

The ACT SB2-HDG6 kit features ACT’s Heavy Duty pressure plate, paired with a 6-pad spring-centered race disc designed for high horsepower street and race applications. This setup delivers quick, positive engagement and improved shifting response, ideal for drivers demanding maximum performance and reliability.

ACT’s Heavy Duty pressure plate uses a proprietary diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. Each unit undergoes a four-stage heat-treating process for consistent performance under extreme conditions.

The 6-pad ceramic race disc features a spring-centered hub to damp torsional vibrations and resist failure in harsh use. Reinforced spring retainers with wraparound windows improve strength and durability. While engagement is aggressive, this design allows for faster, more precise shifting and excellent heat dissipation.
