Description: The BM17-HDR4 kit features ACT's most popular Heavy Duty pressure plate, designed to enhance clutch performance in race environments. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process, ensuring unparalleled durability and performance. Precision cover stampings provide rigidity and consistency for reliable operation.

Paired with the pressure plate are ACT's 4-pad rigid race discs, crafted 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, making it well-suited for smaller engines.

Key Features:

• Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle.
• Life: Moderate friction life, extended by ACT's exclusive diaphragm design; rigid design may increase spline wear.
• Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance.
