Product Details

Description

AA2-HDSD kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an 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 ACT performance street rigid-hub discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. The chrome-moly hub is heat-treated for strength and durability. Rivet design and materials are carefully selected for maximum strength. These discs are the minimum-weight street disc for faster shifts. ACT's street rigid-hub discs provide race-proven performance with street manageability.

Will an ACT clutch increase pedal effort?

ACT pressure plates are specifically designed to handle high-torque applications. With ACT's durable design, expect an increase in pedal effort between 15-40% (Heavy Duty) and 50-80% (Xtreme), depending on the application. Clutches developed with less pedal effort often lack longevity, torque capacity and/or engagement quality.

Product Features
