ACT Heavy Duty Performance Street Sprung Clutch 2002-2018 WRX
DESCRIPTION
The ACT Heavy Duty Performance Street Sprung Clutch for the 2002–2005 Subaru WRX (SB9-HDSS) combines ACT’s popular Heavy Duty pressure plate with the most purchased Performance Street sprung disc. The pressure plate’s exclusive diaphragm design increases clamp load, reduces deflection, and extends clutch life through a four-stage heat-treating process and precision cover stampings.
The sprung Performance Street disc uses premium organic material with high copper content for improved heat transfer and steel-backed lining for durability. Reduced marcel allows faster, smoother shifts, while quiet operation and the patented Monoloc release mechanism provide uniform bearing load, improved alignment, and extended release mechanism life.
WHY?
This clutch kit is ideal for WRX owners seeking a balance of daily drivability and spirited performance. It delivers light to moderate pedal effort, smooth engagement, and confidence during hard shifts. With enhanced friction life and precise engineering, it’s a reliable upgrade for both street and occasional track use.
