ACT Z66-XTR4 Advanced Clutch XT/Race Rigid 4 Pad Kit

The ACT Z66-XTR4 is designed for performance enthusiasts who demand the best from their vehicles. This Advanced Clutch XT/Race Rigid 4 Pad Kit features an Xtreme pressure plate, tailored for those who push their cars to the limit. The exclusive diaphragm design of the pressure plate increases clamp load while minimizing deflection, which not only enhances clutch life but also ensures consistent performance under extreme conditions.

Every diaphragm undergoes a meticulous four-stage heat-treating process, resulting in unparalleled durability and reliability. The precision cover stampings contribute to the rigidity and consistency of the pressure plate, making it a trustworthy choice for serious drivers.

The 4-pad rigid race discs are crafted from high-quality ceramic friction materials, ensuring excellent heat tolerance and performance. The chrome-moly hub is heat-treated, providing both strength and durability. This lightweight and rigid design allows for quicker shifts, making your driving experience smoother and more enjoyable. While the engagement may feel harsher, the trade-off is faster shifting, ideal for those who crave responsiveness.
