Key Features:

This clutch kit incorporates advanced technology and materials to ensure superior performance and durability:

• Sport pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragm for enhanced strength and consistent performance
• Precision cover stampings for improved rigidity and consistent clamp force
• 4-pad rigid race disc constructed with high-quality ceramic friction materials for high heat tolerance
• Heat-treated chrome-moly hub for exceptional strength and durability
• Lightweight, rigid disc design enabling quicker shifts and smooth operation
• Harsher engagement suited for aggressive driving and race conditions
• Dynamic computer balancing and 100% clamp load testing for reliable high RPM performance
• Extended friction life supported by ACT’s exclusive diaphragm design

Construction & Design:

The ACT Sport/Race Clutch Kit is meticulously engineered with premium materials and manufacturing processes to withstand the rigors of performance driving. The Sport pressure plate’s diaphragm spring undergoes a rigorous four-stage heat treatment, enhancing its clamp load capacity and reducing deflection for consistent engagement. The cover features precision stampings that add rigidity, ensuring uniform pressure distribution across the clutch disc.

The 4-pad rigid race disc utilizes select ceramic friction materials that provide excellent heat resistance and friction stability under high-stress conditions. Its chrome-moly hub is heat-treated to deliver superior strength and durability, while the lightweight design reduces rotational mass, contributing to faster engine response and smoother shifts.

Performance & Sound

The 4-pad rigid race disc delivers a more aggressive engagement compared to stock clutches, resulting in quicker, more precise shifts. This harsher engagement is ideal for drivers who prioritize performance and responsiveness, though it may increase gear rattle and pedal effort moderately. The clutch’s design supports high heat tolerance, making it suitable for spirited driving and occasional track use without compromising reliability.

Installation & Fitment:

This clutch kit is a direct fit for 2004 to 2006 Scion xA and xB models, designed to replace the factory clutch assembly without requiring modifications. Professional installation is recommended to ensure proper alignment and optimal performance. The kit is engineered to maintain compatibility with the vehicle’s existing drivetrain components, providing a seamless upgrade experience.

What's Included:

• Sport pressure plate with exclusive diaphragm spring
