ACT Heavy Duty Race Sprung 6-Pad Clutch Kit for 2003-2006 Nissan 350Z and Infiniti G35 (NZ1-HDG6)

Fits select 2003-2006 Nissan 350Z and Infiniti G35 models.

The ACT NZ1-HDG6 Heavy Duty Race Clutch Kit is engineered for high-performance driving and track use where increased clamp load and rapid shifting are essential. This kit pairs ACT's most popular Heavy Duty pressure plate with a 6-pad, spring-centered ceramic race disc, delivering a significant upgrade in torque capacity and thermal management over the factory setup.

The Heavy Duty pressure plate utilizes a proprietary diaphragm design that undergoes a rigorous four-stage heat-treating process to minimize deflection and maximize service life. Precision-stamped covers provide the rigidity needed for consistent engagement. To handle the stresses of racing, the 6-pad race disc features a spring-centered hub to damp torsional vibrations and wraparound spring windows for enhanced support. While engagement is notably harsher than a street disc, the ceramic friction material and sprung hub design provide the durability required for larger clutch sizes and high-heat environments.
