Key Features:

This clutch kit incorporates advanced technology and precision engineering to ensure superior performance and longevity:

• Sport pressure plate with exclusive diaphragm design increases clamp load and reduces deflection for maximum clutch life
• Four-stage heat-treated diaphragms provide unparalleled strength and durability under high stress
• Precision cover stampings enhance rigidity and consistency for reliable engagement
• 4-pad spring-centered race disc dampens torsional vibrations, reducing noise and preventing premature failure
• Wraparound spring windows and thicker retainer stampings improve spring support and increase overall strength
• Spring-centered disc design offers harsher engagement with faster shifting, optimized for smaller disc sizes and engines
• Select ceramic friction materials deliver high heat tolerance and extended friction life
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPMs
• Light to moderate pedal effort with aggressive engagement suitable for street and mild race conditions

Construction & Design:

The ACT Sport/Race Sprung 4 Pad Clutch Kit is meticulously engineered using premium materials and manufacturing processes. The pressure plate’s diaphragm spring undergoes a rigorous four-stage heat treatment to enhance its strength and fatigue resistance, ensuring consistent clamp load throughout its service life. The clutch cover features precision stampings that add structural rigidity, minimizing deflection and improving engagement consistency.

The 4-pad spring-centered race disc is designed with wraparound spring windows and reinforced retainers to support the springs effectively, reducing stress concentrations and enhancing durability. The ceramic friction material is carefully selected for its ability to withstand high temperatures while maintaining strong friction characteristics, making it well-suited for high-performance driving scenarios.

Performance & Sound

This clutch kit delivers a more aggressive engagement compared to stock, resulting in quicker and more precise shifts. The spring-centered design helps dampen torsional vibrations, which reduces gear rattle and contributes to a quieter operation under load. While engagement is firmer, pedal effort remains manageable for street use, making it an excellent choice for drivers who want enhanced performance without sacrificing daily drivability.
