ACT HD/Race Clutch Kits

ACT HD/Race Clutch Kits ACT HD/Race Clutch Kits deliver race-proven strength and precision for street, track, and high-performance builds. Designed for drivers who demand quicker shifts, higher clamp load and long-term durability, these kits combine a hardened pressure plate with a high-friction race disc for aggressive engagement and reliable operation under extreme conditions. Key Features Heavy Duty Diaphragm Pressure Plate — Exclusive diaphragm design increases clamp load, reduces deflection and maximizes clutch life for consistent performance. Four-Stage Heat Treatment — All diaphragms undergo a four-stage heat-treating process to ensure durability and resistance to heat fade. Precision Cover Stampings — Rigid, precision-stamped covers provide structural consistency and improved longevity. 6-Pad Rigid Race Disc — High-quality ceramic friction material on a rigid 6-pad layout for faster engagement and superior heat absorption on larger clutch assemblies. Chrome-Moly Heat-Treated Hub — Strengthened hub construction minimizes wear and improves service life under heavy loads. Lightweight, Rigid Design — Optimized for quick shifts and trouble-free operation without unnecessary rotating mass. Who It’s For Recommended for performance enthusiasts and racers using larger clutch sizes who need higher heat capacity and faster shift response. Expect a firmer engagement compared to street-oriented discs — ideal when ultimate performance and durability are the priority. Upgrade to ACT HD/Race Clutch Kits for proven race-level components engineered to withstand extreme use while delivering consistent, high-performance clutch engagement.
