ACT HD/Race Clutch Kit for GM9-HDG6 with Heavy Duty Diaphragm Pressure Plate

ACT HD/Race Clutch Kit for GM9-HDG6 — Heavy Duty Diaphragm Pressure Plate Performance-focused clutch kit engineered for aggressive street and track use. The GM9-HDG6 pairs ACT’s proven heavy-duty diaphragm pressure plate with a 6-pad spring-centered race disc to deliver increased clamp load, improved durability, and quicker shifts under extreme conditions. Heavy Duty Diaphragm Pressure Plate: Exclusive diaphragm design increases clamp load and reduces deflection for consistent engagement and extended clutch life. Four-stage heat-treated diaphragms: Enhanced strength and thermal resistance for reliable performance under repeated high-heat cycles. Precision cover stampings: Rigid, consistent construction minimizes distortion and maintains even pressure distribution. 6-pad Spring-Centered Race Disc: Spring-center design damps torsional vibrations, resists failure in harsh conditions, and enables faster, crisper shifts. Reinforced spring retainers: Wraparound spring windows and thicker stampings reduce stress concentrations and improve retainer strength and longevity. Recommended for larger clutch sizes and high-heat applications where engagement firmness and rapid shift response are priorities. Ideal for motorsport builds and heavy-duty street performance where durability and consistent clamp are essential.
