Enhance the performance and durability of your Porsche 911 with the ACT HD/Race Clutch Kits, designed for drivers who demand the best in power and reliability. Engineered with precision, these kits offer a perfect blend of power, durability, and responsiveness, ideal for both competitive racing and spirited driving on the road.

The PO2-HDR4 kit is equipped with ACT's acclaimed Heavy Duty pressure plate, renowned for its exclusive diaphragm design. This innovative design effectively increases clamp load, reduces deflection, and optimizes clutch longevity. Every diaphragm undergoes a meticulous four-stage, heat-treating process to ensure exceptional performance durability.

The HD pressure plates are constructed using precision cover stampings that offer remarkable rigidity and consistency, critical for maintaining high performance under demanding conditions. Complementing the pressure plate is the 4-pad rigid race disc, crafted with high-quality ceramic friction materials. This ensures superior strength and extended service life, thanks to its heat-treated chrome-moly hub.

Although the rigid race disc may feel a bit more assertive on engagement, it undeniably offers the benefit of quicker shifts, ideal for those requiring lightning-fast response. This disc configuration is especially suitable for vehicles with smaller disc sizes and engines, providing an edge in performance.
