ZM12-HDG6 - HD/Race Sprung 6 Pad

Product Description: HD/Race Sprung 6 Pad Clutch Kit

The HD/Race Sprung 6 Pad Clutch Kit, identified as the ZM12-HDG6, represents the pinnacle of ACT's engineering prowess. Weighing 27.4 pounds, this kit boasts a remarkable torque capacity of 399 ft/lbs, exceeding 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.

Central to its performance is ACT's highly acclaimed Heavy Duty pressure plate, renowned for its exclusive diaphragm design. This design elevates clamp load, reduces deflection, and maximizes clutch lifespan. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance and durability. Precision cover stampings provide essential rigidity and consistency for enduring performance under the most demanding conditions.

The clutch kit integrates ACT's 6-pad, spring-centered race disc, engineered with premium ceramic friction materials. Featuring a spring-center, this design properly dampens torsional vibrations and enhances resistance to failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings, offering superior spring support, reduced stress concentrations, and increased strength and reliability. While engagement may be firmer with the 6-pad, spring-centered race disc, shifting becomes notably faster. This configuration is particularly recommended for larger clutch sizes to absorb more heat effectively.
