ACT Extreme Performance Street Sprung Clutch Kit 06-26 WRX / 05-12 Legacy GT / 05-09 Outback XT / 06-08 Forester XT / 06 Baja | 532 ft/lbs Torque Capacity | High-Durability Clutch Kit
Overview
The ACT Extreme Performance Street Sprung Clutch Kit is engineered for Subaru enthusiasts who demand a robust and reliable clutch solution capable of handling aggressive street driving and occasional track use. 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 a significant upgrade over factory clutches with a focus on durability and performance.
At the core of this kit is ACT’s Xtreme pressure plate, which utilizes an exclusive diaphragm design that increases clamp load, reduces deflection, and extends clutch life. The pressure plate undergoes a rigorous four-stage heat treatment process to ensure consistent performance under high stress. Complementing this is the premium organic clutch disc featuring high copper content for superior heat transfer and a steel-backed lining for enhanced strength and durability. This combination results in a clutch that balances aggressive engagement with smooth operation and long-lasting reliability.
For Subaru owners, this clutch kit offers a tangible improvement in torque capacity—up to 72% more than the original equipment—making it ideal for those upgrading power levels or seeking a more responsive and durable clutch feel. The moderate to heavy pedal effort and smooth engagement characteristics provide a driving experience that is both connected and manageable, preserving daily drivability while supporting spirited driving. This kit is a practical choice for WRX, Legacy GT, Outback XT, Forester XT, and Baja owners looking to enhance drivetrain performance without sacrificing reliability.
