Product Description

The ACT SB11-HDG6 Heavy Duty 6-puck clutch kit is engineered for turbocharged Subaru platforms requiring substantial increases in torque capacity and performance. Featuring a ceramic 6-puck sprung race disc paired with ACT's Heavy Duty pressure plate, this kit delivers aggressive engagement, rapid shifting, and excellent heat resistance for high-performance street and track builds.

This kit upgrades factory 230mm clutch systems to a stronger 240mm setup and includes a Streetlite flywheel to reduce rotational mass, improving throttle response and acceleration. With up to 574 ft-lbs torque capacity and significantly increased clamp load, it is ideal for modified WRX, Legacy GT, Forester XT, Baja Turbo, and Outback XT applications.

Due to its aggressive engagement characteristics, this clutch is best suited for experienced drivers and performance-focused vehicles. Proper installation and compatibility verification are critical, especially for newer WRX models with updated factory clutch systems. No lift or drop height applies, as this is a drivetrain component.
