The ACT Sport Pressure Plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Every diaphragm goes through a four-stage heat-treating process for consistent performance, and precision cover stampings keep the assembly rigid under load. ACT's Sport pressure plates increase clamp load 20 to 40 percent over stock and are recommended for use with a street disc.
