Overview:

The ACT HD/Race Sprung 4 Pad Clutch Kit is engineered to deliver exceptional performance and durability for the 2005–2006 Scion tC. Designed for enthusiasts seeking a reliable upgrade over the factory clutch, this kit offers aggressive engagement and enhanced clamp load to handle increased horsepower and demanding driving conditions. Whether you're tackling spirited street driving or occasional track use, this clutch kit provides a balance of performance and drivability with moderate pedal effort and extended clutch life.

Built to withstand the rigors of high-performance applications, the ACT HD/Race Sprung 4 Pad kit features a heavy-duty pressure plate and a spring-centered race disc that reduces torsional vibrations and improves shifting response. This clutch kit is ideal for drivers who want a more direct connection to the drivetrain without sacrificing reliability.

Key Features:

ACT’s HD/Race Sprung 4 Pad Clutch Kit incorporates advanced technology and precision engineering to enhance your Scion tC’s performance:

• Heavy Duty pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for superior strength and longevity
• Precision cover stampings to ensure rigidity and consistent performance
• 4-pad spring-centered race disc designed to damp torsional vibrations for quieter operation
• Wraparound spring windows and thicker retainer stampings for enhanced spring support and durability
• Spring-centered disc offers faster shifting with a slightly harsher engagement
• Use of select ceramic friction materials for high heat tolerance and maximum performance
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPM
• Light to moderate pedal effort suitable for aggressive street and mild race use

Construction & Design:

The ACT HD/Race Sprung 4 Pad Clutch Kit is meticulously engineered using high-quality materials and advanced manufacturing processes. The heavy-duty pressure plate features a unique diaphragm spring design that increases clamp load while minimizing deflection, which extends clutch life and improves pedal feel. Each diaphragm undergoes a rigorous four-stage heat treatment to enhance durability under extreme heat and stress.

The 4-pad spring-centered race disc is crafted with ceramic friction materials selected for their ability to withstand high temperatures and maintain consistent performance. The wraparound spring windows and reinforced retainer stampings provide superior spring support, reducing stress concentrations and preventing premature failure. This robust construction ensures the clutch kit performs reliably even in demanding driving scenarios.

Performance & Sound

The 4-pad spring-centered race disc design offers a more aggressive engagement compared to stock clutches, delivering quicker shifts and improved throttle response. While engagement is firmer, pedal effort remains manageable for street use. This clutch kit also helps reduce gear rattle commonly experienced with lighter race discs, providing a balance between performance and noise control. Drivers will appreciate the enhanced connection to the drivetrain and the confidence it brings during spirited driving.

Installation & Fitment:

This clutch kit is a direct fit replacement for the 2005–2006 Scion tC, designed to work seamlessly with the vehicle’s existing transmission setup. Installation requires standard clutch replacement procedures and no major modifications. It is recommended to have the installation performed by a professional or an experienced technician to ensure proper alignment and optimal performance.
