ACT Z64-XTG4 Advanced Clutch XT/Race Sprung 4 Pad Kit

If you're looking to enhance the performance of your 1989-1992 Ford Probe, 1988-1991 Mazda 626, or 1988-1992 Mazda MX-6, the ACT Z64-XTG4 is a clutch kit that delivers serious power and precision. This kit is designed for the most demanding drivers who want to push their vehicles to the limit, whether on the street or the track.

Why Choose the Z64-XTG4?

The Z64-XTG4 features an Xtreme pressure plate that utilizes an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance under extreme conditions. With precision cover stampings, this pressure plate offers rigidity and consistency that you can rely on.

At the heart of this kit is ACT's 4-pad spring-centered race disc. This design not only dampens torsional vibrations for a quieter operation but also resists failure even in the harshest environments. The engagement may feel harsher, but it allows for faster shifting, making it perfect for spirited driving or competitive racing.
