About this product
The Z64-HDR4 kit pairs ACT's acclaimed heavy-duty pressure plate with a high-performance 4-pad rigid race disc, delivering exceptional power-handling capabilities for demanding applications. The heavy-duty pressure plate features an exclusive diaphragm design that increases clamp load, minimizes deflection, and extends clutch life. Each diaphragm undergoes a four-stage heat-treating process to ensure unmatched durability and consistent performance.
The 4-pad rigid race disc is constructed from high-quality ceramic friction materials and features a heat-treated chrome-moly hub for superior strength and durability. Its lightweight and rigid design facilitates quicker shifts and seamless operation. Although the engagement with this disc is harsher, the faster shifting makes it an excellent choice for competitive environments. Ideal for smaller disc sizes in compact engines, the Z64-HDR4 kit is built to withstand the rigors of high-performance driving.
