What is the main benefit of the 4-pad rigid race disc?

The 4-pad rigid race disc is designed for faster shifting and a more direct engagement. Its lightweight, rigid construction helps reduce shift times, making it suitable for performance applications.

How does the Xtreme pressure plate improve clutch life?

The Xtreme pressure plate uses an exclusive diaphragm design that increases clamp load and reduces deflection. This, combined with a four-stage heat-treating process, helps maximize clutch life under demanding conditions.

Does this clutch kit come with all necessary installation hardware?

The manufacturer's description lists the clutch kit itself as included. It is recommended to consult the installation instructions or ACT's technical support to confirm if any additional hardware is required for installation.

Product Details

PO1-XTR4 kit features an Xtreme pressure plate for the most demanding driver. ACT Xtreme pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.
