ACT TC1-XTR4 Clutch Kit

Introducing the ACT TC1-XTR4 Clutch Kit, designed for those who demand performance and reliability from their vehicle's clutch system. This kit features the innovative Xtreme pressure plate, tailored for the most rigorous driving conditions. With its unique diaphragm design, the TC1-XTR4 increases clamp load, minimizes deflection, and ultimately extends the life of your clutch.

Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring top-notch performance and durability. The precision cover stampings add rigidity and consistency, making this clutch kit a favorite among enthusiasts. Customers have noted that the 4-pad rigid race discs made from high-quality ceramic friction materials provide a significant upgrade in their driving experience.
