Product Description

ACT ZM3-HDG4 Heavy Duty Pressure Plate w/ Race Sprung 4 Pad 04-11 Mazda

This Performance Race Kit features ACT's most popular Heavy Duty Pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad, spring-centered race disc features a spring-center construction to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad, spring-centered race disc engagement is harsher, but shifting is faster. ACT's 4-pad, spring-centered race disc is well-suited for smaller disc sizes in smaller engines.
