ACT NX6-HDG4 Heavy Duty/Race Sprung 4 Pad Kit

The ACT NX6-HDG4 Heavy Duty/Race Sprung 4 Pad Kit is specifically engineered for performance-driven applications, delivering enhanced durability and responsiveness. This kit features ACT's renowned Heavy Duty pressure plate, designed using an exclusive diaphragm mechanism that increases clamp load, minimizes deflection, and extends clutch lifespan. Each diaphragm undergoes a rigorous four-stage heat treatment, ensuring optimal performance under demanding conditions.

Construction and Design

ACT pressure plates are crafted with precision cover stampings that enhance rigidity and consistency. The 4-pad spring-centered race disc is engineered to effectively dampen torsional vibrations, resulting in quieter operation while maintaining reliability even in extreme environments. The spring retainers utilize wraparound spring windows and thicker stampings, which provide enhanced support and reduce stress concentrations, ultimately increasing strength and reliability.

Performance Characteristics
