Product Description

The ACT SB5-HDSS Heavy Duty Street Clutch Kit is engineered for drivers seeking enhanced performance and reliability. Featuring a Heavy Duty pressure plate with an exclusive diaphragm design, this kit increases clamp load while reducing deflection, ensuring consistent performance under demanding conditions.
