    Pressure Plate:
    ACT pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency.

    ACT Monoloc:
    Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction will provide years of service.

    Feel:
    Light to moderate pedal effort, smooth positive engagement, OE to mild gear rattle, confidence during hard shifts.

    Life:
    Longer friction life, extended by ACT's exclusive diaphragm design, dramatic improvement in release mechanism life.

    Quality:
    Carefully engineered, precisely assembled, accurately balanced, with premium organic friction materials for heat tolerance and reduced fade, major improvement in release mechanism.

    Recommended Use:
    For street and race use.

    ACT Difference:
    100% clamp load tested and dynamically computer balanced for smooth high RPM reliability, includes ACT's patented Monoloc.
