ZM12-HDR6 - HD/Race Rigid 6 Pad

Product Description: HD/Race Rigid 6 Pad Clutch Kit

The HD/Race Rigid 6 Pad Clutch Kit, identified as the ZM12-HDR6, epitomizes performance excellence from ACT. Weighing 27 pounds, this kit boasts an impressive torque capacity of 399 ft/lbs, surpassing OE standards by an impressive 87%. Constructed with a ceramic disc material, it features a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches.

At its core lies ACT's most renowned Heavy Duty pressure plate, lauded for its exclusive diaphragm design. This design enhances clamp load, diminishes deflection, and maximizes clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unparalleled performance. Precision cover stampings provide rigidity and consistency, crucial for enduring performance under rigorous conditions.

The clutch kit incorporates ACT's 6-pad rigid race discs, crafted with premium ceramic friction materials. The chrome-moly hub is heat-treated for enhanced strength and durability. The lightweight, rigid design enables quicker shifts and smooth, trouble-free service. While engagement may be firmer with the 6-pad rigid race disc, shifting becomes noticeably quicker. This disc configuration is particularly recommended for larger clutch sizes to effectively absorb more heat.
