The Vortech Superchargers 8-rib Pulley Upgrade (PN 4FL116-002) is designed for 2000-2004 Ford Mustang GT applications running Vortech supercharger systems that require improved belt traction and stability at elevated boost levels. This upgrade converts the accessory drive to a robust 8-rib configuration, helping reduce belt slip and maintain consistent boost under load.

Why Upgrade to an 8-Rib Drive?
