ACT HD Race Rigid 4 Pad Clutch Kit w/ Flywheel - 2006-2021 Subaru WRX / 2005-2009 Legacy GT / Outback

ACT's HD Race Rigid 4 Pad Clutch Kit w/ Flywheel features ACT's most popular Heavy Duty pressure plate. This Kit fits 2006-2021 Subaru WRX, and 2005-2009 Legacy and Outback.  ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

 

NOTE: Subaru has increased the clutch component sizes. Aftermarket clutches that include a flywheel must have the flywheel installed, as designed by the manufacturer.

 

The included flywheel must be installed due to a larger clutch components on the OEM clutches.

 

Application Note: 240mm upgrade. Must use ACT flywheel (included in kit).
