ACT ZX4-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit for 2006-2013 Mazda 3/6 Mazdaspeed

Fits 2006-2013 Mazda 3 and Mazda 6 Mazdaspeed models.

The ACT ZX4-HDG6 clutch kit is engineered for high-performance applications where rapid shifting and increased clamp load are essential. This kit pairs ACT's Heavy Duty (HD) pressure plate with a 6-pad spring-centered race disc, providing a significant upgrade over factory components for track-driven and high-torque vehicles. While engagement is naturally harsher than a street-spec kit, the reward is faster gear transitions and superior heat capacity.

The Heavy Duty pressure plate utilizes a proprietary diaphragm design that undergoes a rigorous four-stage heat-treating process. This ensures consistent pedal feel, reduced deflection, and maximum clutch life. Precision cover stampings provide the necessary rigidity for high-stress driving. The included 6-pad race disc features a spring-centered hub to dampen torsional vibrations, protected by wraparound spring windows and thickened retainer stampings for increased reliability under harsh conditions.
