ACT HD/Race Clutch Kit for Chevy C6 Heavy Duty Pressure Plate DN4-HDG6

ACT HD/Race Clutch Kit for Chevy C6 — DN4-HDG6 High‑performance clutch kit engineered for Chevy C6 owners who demand durability, precise engagement, and track-ready strength. The DN4-HDG6 pairs ACT’s most popular Heavy Duty pressure plate with a 6-pad, spring-centered race disc to deliver consistent clamp load and superior heat tolerance. Key Features Exclusive diaphragm design — Increased clamp load and reduced deflection for longer clutch life and consistent engagement. Four-stage heat-treat — Diaphragms undergo precision heat treatment for enhanced strength and stability under high temperatures. Rigid cover stampings — Precision stampings improve cover rigidity and ensure consistent clamp performance. 6-pad spring-centered race disc — Faster, more direct shifts; recommended for larger clutch diameters to absorb more heat. Reinforced spring retainers — Wraparound spring windows and thicker retainers reduce stress concentrations and increase reliability in harsh driving conditions. Why Choose the DN4-HDG6 This kit is ideal for spirited street use and competition where a harsher, faster engagement is acceptable in exchange for improved heat management, torsional damping, and long-term durability. If you need a clutch that stands up to aggressive launches and repeated high-temperature cycles, the ACT DN4-HDG6 delivers proven performance.
