ACT Xtreme Clutch Kit 6 Puck Sprung Disc for 04-21 Subaru STI, 07-09 Legacy GT Spec B

The SB10-XTG6 kit features an Xtreme pressure plate, engineered for the most demanding drivers. Designed with ACT's exclusive diaphragm technology, it delivers increased clamp load, reduced deflection, and extended clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance and durability. Precision cover stampings enhance rigidity and consistency, while the included 6-pad spring-centered race disc provides exceptional torsional vibration damping and reliability under harsh conditions. The race disc's spring retainers feature wraparound spring windows and reinforced retainer stampings for increased strength and stress resistance.

The 6-pad spring-centered race disc ensures faster shifting, though with harsher engagement, making it ideal for larger clutch sizes that require effective heat absorption. The kit also includes the Monoloc, a one-piece upgrade to the standard two-piece wedge collar and wire ring in pull-type clutches. Constructed from hardened chrome-moly steel, Monoloc offers optimal performance with carefully tested spring tension, uniform loading on the bearing and pressure plate, and lasting reliability.

Experience unmatched performance, strength, and precision with the SB10-XTG6 kit, engineered to meet the needs of high-performance driving enthusiasts.
