Vortech 8-Rib Pulley Upgrade - 3.33" Supercharger Pulley w/Belt (2000-2004 Mustang GT) 4FL116-001
8-Rib Supercharger Drive Upgrade for High-Horsepower 2000-2004 Mustang GT Builds
The Vortech Superchargers 8-rib Pulley Upgrade (PN 4FL116-001) is engineered specifically for 2000-2004 Ford Mustang GT applications running Vortech supercharger systems that require increased belt grip and stability at elevated power levels. This upgrade converts the factory-style drive system to a robust 8-rib configuration, dramatically improving belt wrap, traction, and reliability under high boost.
This exact part number includes a 3.33-inch supercharger pulley AND the correct 8-rib drive belt, making it a complete, ready-to-install drive solution for high-horsepower street or race builds.
What This Part Number Is (and Is Not)
- This kit IS: An 8-rib supercharger drive upgrade with a 3.33" S/C pulley and included drive belt (PN 4FL116-001)
- This kit IS: Intended for high-horsepower Vortech-equipped Mustang GTs
- This kit is NOT: A supercharger or complete supercharger system

8-Rib Drive System Advantages
As boost levels and horsepower increase, standard 6-rib drive systems can struggle with belt slip and inconsistent boost delivery. Vortech's 8-rib conversion increases surface contact area across the entire accessory drive, allowing the supercharger to maintain stable boost under load while reducing belt wear.
This upgrade is strongly recommended for vehicles pushing beyond basic entry-level supercharger configurations.
