ACT HD/Race Rigid 4 Pad Kit Scion tC | xB | Toyota Corolla | Matrix 2005-2015 - TC7-HDR4

Upgrade Your Clutch with the ACT TC7-HDR4 Heavy Duty/Race Rigid 4 Pad Kit

If you're looking to elevate your driving experience in your 2005-2010 Scion tC, 2008-2015 Scion xB, 2009-2013 Toyota Corolla, or 2009-2014 Toyota Matrix, the ACT TC7-HDR4 Heavy Duty/Race Rigid 4 Pad Kit is a game-changer. Designed for performance enthusiasts, this kit is engineered to handle the demands of spirited driving while delivering a reliable, responsive clutch feel.

Why Choose the TC7-HDR4?

The TC7-HDR4 features ACT's most popular Heavy Duty pressure plate, which utilizes an exclusive diaphragm design that significantly increases clamp load. This results in reduced deflection and maximized clutch life, making it perfect for both daily drivers and track cars. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unparalleled performance and durability.

ACT's 4-pad rigid race discs are crafted from high-quality ceramic friction materials, providing the necessary bite for aggressive driving. The chrome-moly hub is heat-treated to enhance strength and durability, while the lightweight design allows for quicker shifts and smooth operation. Although the engagement is more aggressive, it translates to faster shifts, making it ideal for those who demand precision on the road or track.
