ACT HC4-HDR6 Clutch Kit

Upgrade your vehicle's performance with the ACT HC4-HDR6 Heavy Duty/Race Rigid 6 Pad Kit. This kit features ACT's renowned Heavy Duty pressure plate, designed specifically for those who demand more from their clutch system. With an exclusive diaphragm design, this pressure plate increases clamp load while minimizing deflection, ensuring a longer clutch life and consistent performance.

One of the standout features of the HC4-HDR6 is its four-stage heat-treating process applied to all diaphragms, providing unparalleled durability and reliability. The precision cover stampings enhance rigidity, making this pressure plate a top choice for enthusiasts and racers alike.

The 6-pad rigid race discs are crafted from high-quality ceramic friction materials, which not only offer excellent heat tolerance but also contribute to quicker shifts and smoother operation. The chrome-moly hub is heat-treated, ensuring strength and longevity under extreme conditions. While the engagement may be harsher, customers have noted that the increased responsiveness and speed during gear changes are well worth it.
