The ACT Heavy Duty pressure plate for the 1981 Nissan 280ZX uses an exclusive diaphragm design to increase clamp load, reduce deflection and extend clutch life. ACT diaphragms undergo a four-stage heat-treating process and precision cover stampings for rigidity; Heavy Duty units raise clamp load 20–50% and are recommended with a street or race disc, backed by a one-year warranty.
