ACT NS1-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit

NS1-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 NS1-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit is engineered for high-performance street and race applications that require increased clamp load, fast shifting, and dependable operation under demanding conditions. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad, spring-centered race disc designed to handle increased heat and aggressive driving. The spring-centered design helps damp torsional vibrations while resisting failure during severe use.

ACT Heavy Duty pressure plates feature an exclusive diaphragm design that increases clamp load, reduces deflection, and helps maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for consistent performance, while precision cover stampings improve rigidity and assembly consistency. The disc uses select ceramic friction materials for high heat tolerance and maximum performance. Engagement is more aggressive than an OE-style clutch, with faster shifting and light to moderate pedal effort. Mild gear rattle may occur depending on the vehicle and drivetrain configuration.
