ACT SB10-HDG6 Heavy Duty 6-Pad Sprung Clutch Kit for Subaru Legacy and Impreza

SB10-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 construction 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. Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened Chrome-moly steel construction will provide years of service. HD-M/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle, confidence during hard shifts; Moderate friction life, extended by ACT's exclusive diaphragm design, dramatic improvement in release mechanism life; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance, major improvement in release mechanism; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability, includes ACT's patented Monoloc

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

The ACT SB10-HDG6 Heavy Duty clutch kit is engineered for high-performance street and race applications requiring dependable clamping force, fast shifting, and improved release mechanism durability. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad spring-centered race disc, providing increased clamp load while helping reduce diaphragm deflection and extend clutch service life. The pressure plate is precision-stamped for rigidity and consistency, and every diaphragm undergoes a four-stage heat-treating process for reliable performance under demanding conditions.

The HD-M/Race Sprung 6 Pad disc uses select ceramic friction materials for high heat tolerance and aggressive engagement. Its spring-centered construction helps damp torsional vibrations and resist failure during hard use, while reinforced spring retainers support the springs, reduce stress concentrations, and improve reliability. Engagement is firmer than a full-face disc, but the design promotes faster shifting and is well suited to larger clutch applications that need greater heat absorption. Pedal effort remains light to moderate for a performance-oriented clutch system.

Included ACT Monoloc technology replaces the standard two-piece wedge collar and wire ring used in pull-type clutch systems. Its hardened chrome-moly steel construction and carefully calibrated segmented retaining ring provide uniform bearing and pressure plate loading for proper alignment, even with driver-induced or vehicle-related variations. The assembly is 100 percent clamp-load tested and dynamically computer balanced for smooth high-RPM operation. ACT backs the kit with a one-year warranty. Fitment data indicates applications for select 2007 and 2009 Subaru Legacy models and 2011 through 2014 Subaru Impreza models; verify drivetrain, engine, transmission, and original equipment specifications before ordering.
