ACT 2007 Mazda 3 HD/Race Rigid 4 Pad Clutch Kit

ACT HD/Race Rigid 4 Pad Kit ZX5-HDR4 features ACT's Heavy Duty pressure plate, designed with an exclusive diaphragm for increased clamp load, reduced deflection, and maximized clutch life. Diaphragms undergo a four-stage heat-treating process. The kit includes 4-pad rigid race discs made with high-quality ceramic friction materials and a heat-treated chrome-moly hub for strength and durability. Its lightweight, rigid design allows for quicker shifts. Engagement is harsher with this 4-pad rigid race disc, but shifting is faster. It is well-suited for smaller disc sizes in smaller engines.
