ACT GM012 Pressure Plate Heavy Duty – American Motors Ambassador
The ACT GM012 pressure plate features an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All ACT 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 Heavy Duty pressure plates increase clamp load by 20 to 50 percent. The Heavy Duty pressure plates are recommended for use with a street or race disc.
