ACT ZM1-XTR4 Clutch Kit

Introducing the ACT ZM1-XTR4 Clutch Kit, designed for the serious driver who demands top-notch performance on the track. This kit features an advanced Xtreme pressure plate that’s built to handle the most intense driving conditions. The unique diaphragm design not only increases clamp load but also minimizes deflection, ensuring your clutch lasts longer under pressure.

Each diaphragm undergoes a meticulous four-stage heat-treating process, which enhances durability and performance. With precision cover stampings, the pressure plates provide the rigidity and consistency you need for high-speed gear changes.
