D017X is an ACT Xtreme pressure plate that uses 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’s Xtreme pressure plates increase clamp load by 50 to 120 percent. Xtreme pressure plates are recommended for use with a street or race disc.
