Heavy Duty Pressure Plate with Performance Street Disc

The ACT Heavy Duty Performance Street Disc Clutch Kit (SB10-HDSS) is engineered to provide reliable performance for both street driving and light racing applications. This kit combines ACT's robust Heavy Duty pressure plate with their Performance Street organic disc, which features a high copper content and steel-backed lining for enhanced heat transfer, durability, and burst strength. The Heavy Duty pressure plate utilizes an exclusive diaphragm design to increase clamp load and minimize deflection, thereby extending clutch life. The organic disc is crafted for smooth engagement and longevity, suitable for daily drivers and street-focused builds with mild to moderate performance upgrades. Its design also aims for quiet operation and increased reliability. Key specifications include a torque capacity of 522 ft/lbs (a 45% increase over OE), a 9.4-inch diameter disc, and a 1-inch input shaft diameter. The kit offers a light to moderate pedal effort with smooth, positive engagement and can produce OE to mild gear rattle, providing confidence during hard shifts. Its recommended use spans both street and race applications. This clutch kit is compatible with 2007-2009 Subaru Legacy models and 2004-2021 Subaru STI models.
