ACT MS1-XXG4 Clutch Kit

For the dedicated driving enthusiast, the ACT MS1-XXG4 is more than just a clutch kit; it's a performance upgrade that transforms your vehicle's handling. Designed with the serious racer in mind, this kit features the innovative MaXX pressure plate, which employs a unique diaphragm design. This design not only boosts clamp load but also minimizes deflection, ensuring longer clutch life and enhanced performance under pressure.

One of the standout features of the MS1-XXG4 is its four-stage heat treatment process applied to the diaphragm. This meticulous approach guarantees exceptional performance, even in the most demanding conditions. Customers have noted how the pressure plate's precision cover stampings provide the rigidity and consistency needed for high-stakes racing.

The included 4-pad spring-centered race disc is engineered to dampen torsional vibrations, resulting in quieter operation while resisting failure during intense use. Users have reported that while the engagement may feel harsher, the trade-off is quicker shifts, making it an ideal choice for those looking to maximize their vehicle's performance on the track.
