The ACT Heavy Duty pressure plate for 1989 Ford Probe uses an exclusive diaphragm design to raise clamp load, reduce deflection and extend clutch life. ACT subjects diaphragms to a four-stage heat-treating process and uses precision cover stampings for rigidity and consistency. Heavy Duty plates increase clamp load about 20–50% and are recommended for use with a street or race disc; a one-year warranty is included.
