The ACT NX6-HDG4 clutch kit offers a high-performance solution designed specifically for high horsepower street and race applications on Nissan 300ZX models from 1990 to 1994. This kit features ACT's most popular Heavy Duty pressure plate, utilizing an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch lifespan. The four-stage heat-treating process applied to all diaphragms ensures durability and reliable performance under demanding conditions. Precision cover stampings provide rigidity and consistency, ensuring smooth engagement and reliable operation. The included 4-pad spring-centered race disc dampens torsional vibrations for quieter operation and reduces the risk of failure under stress, making it suitable for aggressive driving styles. ACT's spring retainers, with wraparound spring windows and thicker stampings, support the springs effectively, reducing stress concentrations and enhancing overall strength and reliability. This combination results in a clutch that delivers harsher engagement and faster shifting, ideal for smaller engine sizes or applications requiring aggressive performance. Engineered with high-quality ceramic friction materials, the clutch can withstand high heat and provides moderate friction life, enabling extended durability. Carefully assembled and dynamically balanced, this kit ensures smooth high-RPM operation, with light to moderate pedal effort and a balance of performance and drivability. Backed by ACT's industry-leading one-year warranty, the NX6-HDG4 is an excellent choice for enthusiasts seeking reliable high-performance clutch components that meet the demands of spirited driving and competitive racing.
