Introducing the ACT GM4-HDG6 Heavy Duty/Race Sprung 6 Pad Kit, a top-tier clutch solution engineered for those who demand performance without compromise. This kit features ACT's renowned Heavy Duty pressure plate, designed with an exclusive diaphragm that enhances clamp load while minimizing deflection. This means you can expect an extended clutch life and reliable performance, even under the most demanding conditions.

The pressure plate undergoes a meticulous four-stage heat-treating process, ensuring it stands up to the rigors of high-performance driving. Customers have praised its durability, stating, "I've put this clutch through its paces at the track, and it holds up beautifully!" With precision cover stampings, the pressure plate offers exceptional rigidity and consistency, making it a dependable choice for both street and race applications.

What sets the GM4-HDG6 apart is its 6-pad, spring-centered race disc. This design effectively dampens torsional vibrations, which helps to prevent failure even in harsh environments. The engagement may feel harsher, but it allows for quicker shifts, which is a significant advantage when every millisecond counts on the track. One satisfied user mentioned, "The engagement is aggressive, but it shifts like a dream!"

Additionally, the spring retainers are engineered with wraparound spring windows and thicker stampings, providing enhanced support and reducing stress concentrations. This meticulous attention to detail increases strength and reliability, ensuring that you can push your vehicle to the limits without worry.
