ZM10-HDR4 - HD/Race Rigid 4 Pad

Product Description: HD/Race Rigid 4 Pad Clutch Kit

The HD/Race Rigid 4 Pad Clutch Kit, identified as the ZM10-HDR4, is engineered by ACT to deliver unparalleled performance for race applications. With a weight of 25.4 pounds, this kit provides an impressive torque capacity of 399 ft/lbs, surpassing OE standards by 87%. Crafted with ceramic disc material, it features a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches.

At the core of this kit lies ACT's renowned Heavy Duty pressure plate, featuring an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring exceptional performance under extreme conditions. Precision cover stampings provide essential rigidity and consistency for enduring performance.

The clutch kit integrates ACT's 4-pad rigid race discs, constructed with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability, enabling quicker shifts and smooth operation. While engagement may be harsher, shifting is faster, making it ideal for smaller disc sizes in smaller engines, where performance is crucial.
