Description: The ZM8-HDSS kit by ACT features their most popular Heavy Duty pressure plate paired with their most popular street disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life.

These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.
