Key Features:

The ACT HD/Race Sprung 4 Pad Clutch Kit incorporates advanced technology and design elements to maximize performance and longevity:

• Heavy Duty pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for superior strength and consistent performance
• Precision cover stampings enhance rigidity and ensure consistent clamp force
• 4-pad spring-centered race disc with spring-center to damp torsional vibrations and reduce noise
• Wraparound spring windows and thicker retainer stampings for improved spring support and durability
• Light to moderate pedal effort with aggressive engagement for faster shifting
• Select ceramic friction materials provide high heat tolerance and extended friction life
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPM
• Designed specifically for smaller disc sizes and engines, optimizing performance for Scion tC and xB models

Construction & Design:

The clutch kit is meticulously engineered using premium materials and manufacturing processes. The Heavy Duty pressure plate features a unique diaphragm spring that undergoes a rigorous four-stage heat treatment, enhancing its strength and resistance to fatigue. This design increases clamp load while minimizing deflection, which contributes to longer clutch life and consistent engagement.

The 4-pad sprung race disc is crafted with select ceramic friction materials that tolerate high temperatures generated during aggressive driving. Its spring-centered design effectively dampens torsional vibrations, reducing noise and preventing premature failure. The wraparound spring windows and reinforced retainers provide additional support to the springs, ensuring durability under demanding conditions.

Performance & Sound

This clutch kit delivers a more aggressive engagement compared to stock setups, resulting in quicker and more precise shifts. While the engagement is harsher, it remains manageable with light to moderate pedal effort, making it suitable for both street and race environments. The spring-centered disc design helps reduce gear rattle commonly associated with performance clutches, providing a quieter operation without compromising performance.

Installation & Fitment:

The ACT HD/Race Sprung 4 Pad Clutch Kit is a direct fit replacement for the Scion tC (2006–2010) and Scion xB (2008–2015) models. Installation requires standard clutch replacement procedures and is compatible with stock flywheels. No major modifications are necessary, making it an ideal upgrade for enthusiasts looking to enhance clutch performance with minimal hassle.
