Overview
The ACT Heavy Duty Performance Street Sprung Clutch Kit is engineered for Subaru enthusiasts seeking a robust upgrade to their factory clutch system. Designed to fit a broad range of Subaru models including the 2006-2026 WRX, 2005-2012 Legacy GT, 2005-2009 Outback XT, 2006-2008 Forester XT, and 2006 Baja, this kit delivers enhanced torque capacity and durability for both spirited street driving and occasional track use. It’s ideal for drivers who demand a clutch that can handle increased power without sacrificing smooth engagement or pedal feel.
ACT’s design philosophy centers on maximizing clamp load and clutch life through their exclusive diaphragm pressure plate technology. Each pressure plate undergoes a rigorous four-stage heat-treating process to ensure consistent performance and resistance to deflection under high stress. The clutch disc features premium organic materials with high copper content for superior heat transfer and durability, combined with a steel-backed lining to withstand burst forces. This combination results in a clutch kit that balances strength, reliability, and drivability.
For Subaru owners, this clutch kit offers a significant upgrade over OEM components, boasting a 46% increase in torque capacity. The sprung design reduces gear rattle and provides smooth, positive engagement with light to moderate pedal effort. Whether upgrading a daily driver or preparing a car for mild racing conditions, this kit enhances clutch performance while maintaining street-friendly characteristics.
