This kit features ACT's Xtreme pressure plate, which utilizes an exclusive diaphragm design to significantly increase clamp load and minimize deflection, thereby extending clutch life. The diaphragms undergo a rigorous four-stage, heat-treating process for exceptional durability and performance.\n\nThe kit includes ACT's popular Performance Street Disc, constructed with premium organic materials and high copper content for superior heat transfer. Its steel-backed lining provides greater burst strength and longevity. The disc is designed with reduced marcel for faster, more responsive shifting, complementing the Xtreme pressure plate.\n\nSpecifications for the SB11-XTSS kit include a torque capacity of 510 ft-lbs, representing a 51% increase over the original equipment.
