The ACT HD/Perf Street Sprung Kit (NX4-HDSS) is designed for high-performance applications. This kit features ACT's popular Heavy Duty pressure plate and street disc. The Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. The precision cover stampings provide rigidity and consistency. The performance street disc features premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. The reduced marcel ensures faster shift action, complementing the ACT pressure plates for increased strength and reliability.
