ACT MS1-XTG4 Clutch Kit

The ACT MS1-XTG4 is designed for the serious driver who demands performance and reliability. This clutch kit features an Xtreme pressure plate that utilizes an exclusive diaphragm design, delivering increased clamp load and reduced deflection. This means you get a longer-lasting clutch that can handle the most intense driving conditions. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring top-notch performance.

One of the standout features of the MS1-XTG4 is its 4-pad spring-centered race disc. This unique construction not only dampens torsional vibrations for a quieter operation but also stands up to harsh conditions without failing. Customers have noted that while the engagement might be harsher, they appreciate the faster shifting response that comes with it.

Moreover, the robust spring retainers are designed with wraparound spring windows and thicker stampings, providing added support and reliability. This clutch kit is particularly well-suited for smaller disc sizes in smaller engines, making it a versatile choice for high-performance street or race applications.
