ACT HD Performance Street Sprung Clutch Kit | 2006-2025 Subaru WRX (SB11-HDSS)

SB11-HDSS Heavy Duty Performance Street Sprung Clutch Kit by ACT

SB11-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. 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 Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.

Please Note: Conversion Kit. Replaces original 230mm clutch. Must use ACT Flywheel (included in kit). Subaru has incorporated 240mm clutch components into production during mid-2018MY production starting with VIN J806877. ACT clutch kits and flywheels are not compatible with the revised OEM components.
