ACT NX1-HDG6 Heavy Duty 6-Pad Sprung Clutch Kit

NX1-HDG6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. HD/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT NX1-HDG6 Heavy Duty 6-Pad Sprung Clutch Kit is engineered for high-performance street and race applications that demand increased clamp load, reliable heat management, and fast shifting. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad, spring-centered race disc to provide strong power transfer while helping damp torsional vibrations through the drivetrain.

The ACT Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and help maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for consistent performance, while precision cover stampings improve rigidity and balance. The included 6-pad disc uses select ceramic friction materials for high heat tolerance and aggressive engagement. Its spring-centered design helps resist failure under harsh conditions, while wraparound spring windows and thicker spring retainers improve support, strength, and reliability.

The NX1-HDG6 delivers light to moderate pedal effort with harsher engagement, faster shifting, and OE to mild gear rattle characteristics. It is recommended for larger clutch applications, high-horsepower street vehicles, and race use where the clutch must absorb substantial heat. Every ACT clutch kit is 100% clamp-load tested and dynamically computer balanced to promote smooth, reliable operation at high RPM. The kit is backed by ACT’s one-year warranty and is designed for select Nissan applications, including the Nissan 720 and Nissan 240SX listed in the available fitment data. Verify the vehicle’s engine, transmission, and application details before installation.

Fitment: Available data lists select 1984–1986 Nissan 720 and 1995–1997 Nissan 240SX applications. Confirm exact fitment before purchase.
