Key Features:

This 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 heat resistance
• Precision cover stampings enhance rigidity and consistency across the pressure plate
• 4-pad spring-centered race disc engineered to damp torsional vibrations for quieter operation
• Wraparound spring windows and thicker retainer stampings provide enhanced spring support and durability
• Spring-centered disc design reduces failure risk under harsh driving conditions
• Light to moderate pedal effort with aggressive engagement for faster shifting
• Use of select ceramic friction materials for high heat tolerance and extended friction life
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPM
• Backed by ACT’s industry-leading one-year warranty

Construction & Design:

The ACT Race Sprung 4 Pad Clutch Kit is meticulously engineered with high-quality materials and precision manufacturing processes. The Heavy Duty pressure plate features a unique diaphragm spring design that undergoes a rigorous four-stage heat treatment, ensuring exceptional strength and resistance to wear. This design increases clamp load while minimizing deflection, which translates to improved clutch engagement and longer service life.

The 4-pad spring-centered race disc is crafted with select ceramic friction materials that provide excellent heat tolerance and consistent performance under high-stress conditions. The wraparound spring windows and reinforced retainer stampings enhance the durability of the springs, preventing premature failure and maintaining reliable torsional damping. The entire assembly is dynamically balanced to ensure smooth operation, even at elevated engine speeds.

Performance & Sound

The 4-pad spring-centered race disc offers a harsher engagement compared to stock clutches, delivering quicker and more precise shifts ideal for aggressive driving styles. While the engagement is firm, the spring-centered design helps to dampen torsional vibrations, reducing noise and harshness typically associated with race-oriented clutches. This balance makes it suitable for high horsepower street or race use, providing both performance gains and manageable sound characteristics.

Installation & Fitment:

The ACT Race Sprung 4 Pad Clutch Kit is a direct fit replacement for the Scion xD models from 2008 to 2014. Installation requires standard clutch replacement procedures and is compatible with the factory flywheel. No major modifications are necessary, making it a straightforward upgrade for experienced mechanics or professional installers. Proper break-in and adjustment will ensure optimal performance and longevity.
