Product Description: HD/Race Sprung 4 Pad Clutch Kit

The HD/Race Sprung 4 Pad Clutch Kit, identified as ZM2-HDG4, represents a pinnacle of performance engineering by ACT. Weighing 12.4 pounds, this kit offers a torque capacity of 310 ft/lbs, surpassing OE standards by an impressive 74%. Crafted 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 popular Heavy Duty pressure plate, renowned for its exclusive diaphragm design. This design enhances clamp load, reduces deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance. Precision cover stampings provide rigidity and consistency, essential for enduring performance under extreme conditions.

The clutch kit incorporates a 4-pad spring-centered race disc, engineered to withstand harsh conditions. The spring-centered design effectively dampens torsional vibrations, ensuring quieter operation and resistance to failure. ACT's spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability.

Key Features:

• Feel: Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle.
• Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
• Quality: Carefully engineered, precisely assembled, accurately balanced, employing select ceramic friction materials for high heat tolerance and maximum performance.
• Recommended Use: Ideal for high horsepower street or race applications.
• ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer-balanced for smooth operation even at high RPMs.
