ACT HD/Race Rigid 4 Pad Clutch Kit

2006–2010 Scion tC / 2008–2015 Scion xB (xB2)

TC7-HDR4

Overview:

The ACT HD/Race Rigid 4 Pad Clutch Kit is engineered for serious enthusiasts and racers who demand aggressive engagement and reliable performance from their clutch system. Designed specifically for the Scion tC (2006–2010) and Scion xB (2008–2015), this kit features ACT’s most popular Heavy Duty pressure plate combined with a rigid 4-pad race disc. It delivers increased clamp load and durability, making it ideal for high-stress driving conditions where quick shifts and consistent clutch response are critical.

This clutch kit is perfect for drivers looking to upgrade from stock components to a more robust setup that can handle spirited street driving and track use. While engagement is notably firmer, the kit ensures faster shifting and improved drivetrain feedback, enhancing overall driving dynamics.

Key Features:

Built with precision and performance in mind, the ACT HD/Race Rigid 4 Pad Clutch Kit offers the following key features:

  • Heavy Duty diaphragm pressure plate with exclusive four-stage heat treatment for superior clamp load and reduced deflection
  • Rigid 4-pad race disc constructed with high-quality ceramic friction materials for excellent heat tolerance and consistent engagement
  • Chrome-moly heat-treated hub designed for enhanced strength and durability under high torque loads
  • Lightweight, rigid disc design that enables quicker shifts and smooth operation
  • Precision cover stampings on the pressure plate to improve rigidity and maintain consistent performance
  • Dynamic computer balancing and 100% clamp load testing for reliable high RPM operation
  • Moderate pedal effort with aggressive engagement suited for race and high-performance street applications
  • Extended friction life supported by ACT’s exclusive diaphragm design

Construction & Design:

The ACT HD/Race Rigid 4 Pad Clutch Kit is meticulously engineered using premium materials and advanced manufacturing techniques. The pressure plate features a unique diaphragm spring design that undergoes a rigorous four-stage heat treatment process, ensuring maximum clamp load and longevity while minimizing deflection during heavy use.

The 4-pad rigid race disc utilizes select ceramic friction materials known for their high heat tolerance and consistent friction characteristics. Its chrome-moly hub is heat-treated to withstand the stresses of aggressive driving and racing conditions. The lightweight yet rigid construction of the disc reduces rotational mass, contributing to faster engine response and smoother shifts.

Performance & Sound

This clutch kit delivers a more aggressive and direct engagement compared to stock setups, resulting in quicker, more precise shifts. Drivers will notice increased gear rattle typical of rigid race discs, which is a trade-off for enhanced performance and clutch feel. The pedal effort remains light to moderate, allowing for controlled operation without excessive fatigue during spirited driving or track sessions.

Installation & Fitment:

The ACT HD/Race Rigid 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 may be best performed by a professional or experienced enthusiast. No major modifications are necessary, but proper break-in and adjustment are recommended to ensure optimal performance and longevity.

What's Included:

  • ACT Heavy Duty diaphragm pressure plate
  • Rigid 4-pad ceramic friction race disc with chrome-moly hub
  • Installation hardware (as applicable)
  • Detailed installation instructions

Ideal For:

This clutch kit is ideal for Scion tC and xB owners who participate in light to moderate racing, autocross, or aggressive street driving. It suits drivers seeking a durable clutch with faster engagement and improved shift response, especially those running smaller engines where a rigid 4-pad disc is advantageous. Recommended for race use and high-performance applications where clutch longevity and consistent clamp load are priorities.
