Description: The PO3-HDSD kit features ACT's popular Heavy Duty pressure plate. It utilizes an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life.

The performance street rigid-hub discs are constructed with premium organic materials containing high copper content for improved heat transfer. Steel-backed lining enhances burst strength and durability. The chrome-moly hub is heat-treated for added strength and durability. Rivet design and materials are carefully chosen for maximum strength. These discs are designed to be the minimum weight street disc for faster shifts. ACT's street rigid-hub discs offer race-proven performance with street manageability.

Better than Kilmat
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
Great adhesion, and you can immediately see the sound difference when you rap the area and compared it to another area without it. Also, very easy to cut and apply. Once on, you may not be able to peel it and reposition it, so be sure where you want it.
