About this product
The SB8-HDSS kit pairs ACT’s Heavy Duty pressure plate with their Performance Street disc, optimized for street and light race use. 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 provides superior heat transfer, durability, and burst strength. Reduced marcel design allows faster, smoother shifts. Compatible with Prolite flywheels for enhanced performance.
