ACT Mod-Twin 225 Extreme Duty Sprung Street Twin Disk Clutch Kit 2006-2025 WRX / 2005-2012 Legacy GT / 2006-2008 Forester XT / 2005-2009 Outback XT

The ACT Mod-Twin 225 XT Sprung Street Kit is engineered for high-powered AWD street cars, delivering uncompromised pedal feel, smooth engagement, and extreme torque capacity. By combining twice the organic friction surfaces with an ultra-durable spring-center Mono-Drive hub, this fully modular design maximizes performance and drivetrain longevity.

Each diaphragm spring undergoes a four-stage heat treating process to ensure a consistent, light pedal feel, while steel-backed friction plates with premium organic materials provide stable friction, high heat capacity, and long clutch life. Torque is uniformly transferred to the Mono-Drive hub, reducing driveline shock and extending input shaft life.
