Construction & Design:

The ACT Race Sprung 4 Pad Clutch Kit is meticulously engineered using premium materials and advanced manufacturing techniques. The heavy duty pressure plate features a diaphragm spring that undergoes a rigorous four-stage heat treatment process, enhancing its strength and longevity while maintaining consistent clamp load. Precision cover stampings add structural rigidity, minimizing deflection under load for reliable clutch engagement.

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 preventing premature failure. The ceramic friction material is carefully selected to withstand high temperatures generated during aggressive driving, ensuring consistent performance and durability over time.

Performance & Sound

The 4-pad spring-centered race disc provides a harsher engagement compared to stock clutches, delivering quicker, more precise shifts favored in performance driving. While engagement is aggressive, the spring-centered design helps dampen torsional vibrations, resulting in quieter operation and reduced gear rattle. This clutch kit is well-suited for smaller engines and disc sizes, making it an excellent choice for the Scion xA and xB platforms where quick throttle response and reliable power transfer are essential.

Installation & Fitment:

Designed as a direct fit replacement for 2004–2006 Scion xA and xB models, the ACT Race Sprung 4 Pad Clutch Kit installs using factory mounting points and hardware. Installation typically requires standard clutch replacement procedures without the need for modifications. For optimal performance and longevity, professional installation and proper break-in are recommended.
