ACT NA1-HDG6 Heavy Duty/Race Sprung 6 Pad Kit

The ACT NA1-HDG6 Heavy Duty/Race Sprung 6 Pad Kit is engineered for performance-driven applications, making it an excellent choice for those looking to enhance their clutch system. This kit features ACT's renowned Heavy Duty pressure plate, designed with an exclusive diaphragm that increases clamp load while minimizing deflection, ensuring a longer clutch life under demanding conditions.

Construction and Design

Each diaphragm undergoes a rigorous four-stage heat-treating process, which results in exceptional durability and performance. The precision cover stampings of the pressure plate contribute to its rigidity and consistency, essential for high-stress environments.

Disc Specifications

The kit includes a 6-pad, spring-centered race disc that effectively dampens torsional vibrations, making it reliable even in harsh conditions. The spring retainers are constructed with wraparound spring windows and thicker stampings, providing enhanced support and reducing stress concentrations. This design allows for faster shifting, although it may result in a harsher engagement feel, ideal for performance applications.
