Description:

The NS1-HDG4 kit features ACT's popular Heavy Duty pressure plate, renowned for its exclusive diaphragm design that enhances clamp load, reduces deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance. Precision cover stampings provide rigidity and consistency. The 4-pad spring-centered race disc, crafted from high-quality ceramic friction materials, features a spring center to damp torsional vibrations and resist failure even under harsh conditions. ACT's spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and enhance strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster, making it ideal for smaller disc sizes in smaller engines.
