Product Description: HD/Race Rigid 4 Pad Clutch Kit

The HD/Race Rigid 4 Pad Clutch Kit, identified as Z66-HDR4, is meticulously engineered by ACT to deliver exceptional performance in racing applications. Weighing 12.3 pounds, this kit boasts a torque capacity of 355 ft/lbs, exceeding OE standards by 87%. It features a ceramic clutch disc material with an 8.8-inch (224mm) diameter and an input shaft diameter of 0.9375 inches.

At its heart lies ACT's renowned Heavy Duty pressure plate, featuring an exclusive diaphragm design that enhances clamp load, minimizes deflection, and maximizes clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unmatched performance even under the most demanding racing conditions. Precision cover stampings provide rigidity and consistency for reliable operation.

Paired with the pressure plate is ACT's 4-pad rigid race disc, crafted with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability, offering a lightweight, rigid design that allows for quicker shifts and smooth, trouble-free service. The 4-pad rigid race disc delivers harsher engagement but faster shifting, making it ideal for smaller disc sizes in smaller engines.
