ACT HD 6-Pad Sprung Clutch Kit with Flywheel - SB11-HDG6

240mm Conversion Kit | 574 ft-lb | Ceramic Sprung Disc | Streetlite Flywheel

The ACT SB11-HDG6 Heavy Duty 6-Pad Race Sprung kit converts the listed Subaru applications to a matched 240mm clutch and Streetlite flywheel assembly. Its ceramic race disc and Heavy Duty pressure plate provide a 574 ft-lb engine torque rating, with a spring-centered hub to reduce torsional shock through the driveline. The six-pad layout supports demanding heat conditions, but engagement is more abrupt than an organic street disc. The required ACT flywheel, release bearing, pilot bearing, alignment tool, and pressure plate bolts are included. Follow the conversion requirements below, particularly on WRX models with revised factory 240mm components introduced during the 2018 model year.
