ACT HD/Race Sprung 6 Pad Kit Nissan 180SX 1989-1998

ACT NS4-HDG6 Heavy Duty/Race Sprung 6 Pad Kit

The ACT NS4-HDG6 kit is engineered for those who demand superior performance from their clutch system. Featuring ACT's Heavy Duty pressure plate, this kit utilizes a unique diaphragm design that enhances clamp load, minimizes deflection, and extends clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring durability under high-stress conditions.

Pressure Plate and Disc Design

ACT's pressure plates are crafted with precision cover stampings, providing the necessary rigidity and consistency required for high-performance applications. The 6-pad, spring-centered race disc is designed to effectively dampen torsional vibrations, making it ideal for aggressive driving styles. This setup results in a harsher engagement, facilitating quicker shifts that are essential for competitive racing environments.
