ACT NS3-HDR6 HD/Race Rigid 6-Pad Clutch Kit

NS3-HDR6 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 rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat. HD/Race Rigid 6 Pad Light to moderate pedal effort, aggressive engagement, increased gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for race use only; 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 NS3-HDR6 HD/Race Rigid 6-Pad Clutch Kit is engineered for high-performance and race applications that demand fast shifting, high heat tolerance, and dependable operation at elevated engine speeds. This kit combines ACT’s Heavy Duty pressure plate with a rigid six-pad ceramic race disc for aggressive engagement and consistent power transfer. It is recommended for race use only and is designed to support larger clutch sizes that can absorb more heat during demanding driving conditions.

The ACT Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and help maximize clutch service life. Each diaphragm undergoes a four-stage heat-treating process, while the precision-stamped cover provides improved rigidity and consistency. The pressure plate is 100% clamp-load tested and dynamically computer balanced to promote smooth, reliable performance at high RPM.

The rigid six-pad disc uses select ceramic friction materials for high-temperature performance and a heat-treated chrome-moly hub for strength and durability. Its lightweight, rigid construction supports quicker shifts, although the aggressive engagement may increase gear rattle and spline wear. The disc provides moderate friction life, which is extended by ACT’s diaphragm design and carefully engineered assembly. The kit delivers light to moderate pedal effort with a harsher engagement tailored to competitive driving. ACT backs the NS3-HDR6 with its industry-leading one-year warranty. Professional installation and proper break-in procedures are recommended.

Fitment: Vehicle-specific fitment data was not provided. Verify application compatibility using the vehicle’s year, make, model, engine, transmission, and existing clutch specifications before ordering.
