The ACT SB9-XTSS clutch kit is designed for demanding drivers seeking maximum performance and durability. Featuring an Xtreme pressure plate, this kit uses an exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life, making it ideal for street and race applications. All diaphragms undergo a four-stage heat-treating process to ensure exceptional performance and longevity. The precision cover stampings provide added rigidity and consistency, contributing to smooth engagement and reliable operation. The kit includes ACT’s popular performance street disc, crafted from premium organic materials with higher copper content for superior heat transfer, backed with steel for greater burst strength and durability. These discs are designed with a reduced marcel, allowing for faster shift action, which complements the pressure plate for more responsive performance. Quiet operation combined with increased strength ensures dependable service over time.
The Monoloc, a one-piece direct replacement for the standard wedge collar and wire ring, delivers uniform load distribution on the bearing and pressure plate. Its hardened chrome-moly steel construction guarantees long-lasting performance and consistent alignment, regardless of driver influence or vehicle modifications. The clutch kit’s components are carefully engineered, assembled, and dynamically balanced to provide smooth high-RPM reliability. This kit is recommended for drivers who require a balance of moderate to heavy pedal effort, confident engagement, and extended friction life. It ensures a dramatic improvement in release mechanism durability and heat tolerance, making it suitable for both street and competitive use.
Backed by ACT’s industry-leading one-year warranty, the SB9-XTSS kit offers excellence in performance, reliability, and ease of installation. It is compatible with a range of Subaru models, including various years of Subaru Legacy, Impreza, and Baja, providing a versatile upgrade for enthusiasts seeking enhanced clutch performance and longevity.
