The ACT Heavy Duty Street Sprung Clutch Kit (Part Number: actSB10-HDSS) is engineered to deliver reliable performance for street and light racing applications on Subaru models including the Impreza and Legacy. This kit combines ACT's most popular heavy-duty pressure plate with a high-performance street disc, providing an excellent balance of strength, durability, and smooth engagement. The pressure plate features an exclusive diaphragm design that increases clamp load, reduces deflection, and enhances clutch life, ensuring consistent performance even under demanding driving conditions. All diaphragms undergo a four-stage heat-treating process, offering unparalleled durability and heat resistance. Precision cover stampings add rigidity and consistency to the assembly, contributing to reliable operation and longevity. The included performance street disc is crafted from premium organic materials with high copper content for superior heat transfer and a steel-backed lining for increased burst strength and durability. Its reduced marcel design ensures faster shift action, making it ideal for drivers seeking quick and confident gear changes. This clutch kit also includes ACT's Monoloc, a one-piece, hardened chrome-moly steel collar that replaces the standard wedge collar and wire ring, providing uniform loading on the bearing and pressure plate. This feature ensures proper alignment and consistent performance regardless of modifications or driver influence. The entire assembly is carefully engineered, precisely assembled, and dynamically balanced to ensure smooth, high-RPM operation. Constructed with premium organic friction materials, the kit offers excellent heat tolerance and reduced fade, extending the lifespan of the clutch components. Designed for both street and race use, this clutch kit provides light to moderate pedal effort, smooth engagement, and confidence during hard shifts. It also offers a significant improvement in release mechanism life and is backed by ACT's industry-leading one-year warranty. Compatible with various Subaru models, including 2007 to 2014 Impreza and Legacy, this clutch kit is a reliable upgrade for enthusiasts seeking enhanced performance and durability.
