The ACT Heavy Duty pressure plate for 1991 Geo Prizm increases clamp load by 20–50% using an exclusive diaphragm design to reduce deflection and extend clutch life. Diaphragms receive a four-stage heat treatment for durability and the precision cover stamping ensures rigidity and consistent operation. Recommended for use with a street or race disc, it pairs with heavy-duty setups where added clamp load and reliability matter.
