ACT XT / Performance Street Sprung Clutch Kit for Select 2005-2025 Subaru (SB12-XTSS)

Fits select 2005-2025 Subaru Baja, Forester, Impreza, Legacy, Outback, and WRX models. This SB12-XTSS kit is engineered for the demanding driver who requires significantly increased clamp load without sacrificing street drivability.

The centerpiece of this kit is the ACT Xtreme pressure plate. Utilizing an exclusive diaphragm design, this pressure plate increases clamp load and reduces deflection for more consistent engagement. Each diaphragm undergoes a rigorous four-stage heat-treating process, while the precision-stamped cover provides the rigidity needed for high-performance applications. The Performance Street Sprung disc features a premium organic friction material with high copper content for superior heat transfer and a steel-backed lining for increased burst strength and durability. By reducing the marcel (the wavy spring between friction surfaces), ACT achieves faster shift action to perfectly complement the high-clamp pressure plate.
