Details

SB10-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty 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.

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.

  1. Excellent clutch

    By Dman October 25, 2022

    Just got my sti clutch changed again with this same one. The last one lasted 70k miles with alot of abuse. The only thing that broke was the release bearing. It got disconnected from the pressure plate and broke off the clutch fork. I got it again because it didnt fail completely but i believe a stronger release bearing would be best here
