ACT HD/Race Rigid 4 Pad Kit - BM17-HDR4

BM17-HDR4 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 a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

• Light to moderate pedal effort, aggressive engagement, increased gear rattle
• Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
• Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
• Recommended for race use only
• 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability
