Product Description

The ACT SB9-XTSS Extreme Duty Street Sprung Clutch Kit is a high-performance clutch solution engineered for turbocharged Subaru and Saab applications including 2002-2005 WRX, Forester XT, Baja Turbo, Legacy turbo models, and the Saab 9-2X Aero. Featuring ACT's Xtreme diaphragm pressure plate and a sprung organic clutch disc, this kit provides significantly increased torque capacity with smooth engagement and reliable performance for street and occasional track use. The Monoloc one-piece clutch collar improves release bearing alignment and durability over traditional two-piece designs.

With a torque capacity of approximately 505-511 ft-lbs, this kit accommodates higher power levels while retaining manageable pedal effort. The organic sprung disc ensures smoother shifting and extended friction life, and the dynamically balanced assembly supports high-RPM reliability. Installation includes the required bearings and alignment tool, though a compatible flywheel must be purchased separately. Ideal for enthusiasts seeking a reliable, performance street clutch upgrade without resorting to race-only hardware.
