Product Description

Introducing the one-of-a-kind NX4-HDSS kit, showcasing the fusion of ACT's all-time favorite Heavy Duty pressure plate and their renowned street disc. Elevating the clutch game, ACT Heavy Duty pressure plates employ an exclusive diaphragm design, expertly crafted to amplify clamp load, quell deflection, and extend clutch life beyond all known boundaries. Each diaphragm undergoes an extraordinary four-stage, heat-treating process, securing an unrivaled level of performance. Behold the precision cover stampings, adorning the ACT pressure plates, infusing them with the essence of rigidity and unwavering consistency. Enchanting us further, ACT's Performance Street discs are draped in premium organic materials, boasting a copper-rich core for peerless heat transfer, while a steel-backed lining fortifies their burst strength and endurance, making them an unstoppable force. The reduced marcel in these discs sets the stage for swift shift action, effortlessly harmonizing with the ACT pressure plates, now imbued with heightened strength and unwavering reliability. Together, they are a symphony of perfection, promising an automotive experience like no other.
