The ACT Heavy Duty pressure plate for 2006 Subaru Impreza uses an exclusive diaphragm design to increase clamp load, reduce deflection and extend clutch life. Diaphragms undergo a four-stage heat-treat process and precision cover stampings add rigidity. Heavy Duty units boost clamp load roughly 20–50% and are recommended for use with a street or race disc; Monoloc one-piece retaining ring and chrome-moly construction improve alignment and durability, backed by a one-year warranty.
