ACT Heavy Duty Performance Street Disc Clutch 02-05 WRX / 04-05 Forester / 07-09 Legacy Spec. B
The SB9-HDSS kit combines ACT’s Heavy Duty pressure plate with their Performance Street disc for smooth, reliable street and light race performance. The diaphragm-style pressure plate increases clamp load, reduces deflection, and maximizes clutch life. The premium organic disc with high copper content and steel-backed lining improves heat transfer, durability, and burst strength. Reduced marcel design allows quicker shifts, while the Monoloc one-piece collar ensures proper alignment and improved release mechanism life. Quiet operation, increased reliability, and long-lasting performance make this kit ideal for high-performance street use.
