The ACT heavy duty pressure plate for 2005 Mazda3 uses an exclusive diaphragm design to increase clamp load, reduce deflection and extend clutch life. ACT’s diaphragms undergo a four-stage heat-treating process and precision cover stampings add rigidity and consistency. The Heavy Duty unit raises clamp load by 20–50% and is recommended for use with a street or race disc; backed by ACT’s one-year warranty.
