The ACT SB9-HDSS clutch kit is engineered for high performance and durability, making it an excellent choice for street and light race applications on Subaru Impreza and Legacy models. Featuring ACT's most popular Heavy Duty pressure plate, this kit utilizes an exclusive diaphragm design that enhances clamp load, minimizes deflection, and maximizes clutch lifespan. Each diaphragm undergoes a rigorous four-stage heat-treating process to ensure unparalleled strength and consistency, while precision cover stampings provide added rigidity for reliable operation.
The performance street disc included in this kit is crafted from premium organic materials with high copper content, facilitating superior heat transfer and reduced fade during aggressive driving. Its steel-backed lining offers increased burst strength and durability, complemented by a reduced marcel for quicker shift engagement. This combination results in a quieter operation with increased strength and reliability, ideal for spirited street driving or mild track use.
The Monoloc design is a key feature, a one-piece, direct replacement for standard wedge collars and wire rings, ensuring optimal spring tension and uniform load distribution on the bearing and pressure plate. Constructed from hardened chrome-moly steel, Monoloc provides long-lasting performance and consistent alignment, regardless of modifications or driver influence. Carefully engineered, balanced, and assembled, this clutch kit includes premium organic friction materials designed to withstand high temperatures and reduce fade, offering a significant improvement in release mechanism life.
Backed by ACT’s industry-leading one-year warranty, the SB9-HDSS kit delivers excellence in performance and reliability. It is recommended for enthusiasts seeking a durable, high-quality clutch solution that balances smooth engagement with robust construction, suitable for both daily driving and spirited street use. The kit's design ensures a confident shift experience with longer friction life and dependable high-RPM operation, making it a versatile upgrade for compatible Subaru and Saab vehicles.
