Vortech 8-Rib Pulley Upgrade - 2.95" Supercharger Pulley (No Belt) (2000-2004 Mustang GT) 4FL116-003
8-Rib Supercharger Drive Upgrade for High-Boost 2000-2004 Mustang GT Applications
The Vortech Superchargers 8-rib Pulley Upgrade (PN 4FL116-003) is designed for 2000-2004 Ford Mustang GT vehicles equipped with Vortech supercharger systems that demand maximum belt grip under increased boost. This upgrade converts the factory-style drive to a heavy-duty 8-rib configuration, significantly reducing belt slip and maintaining consistent boost levels in high-horsepower builds.
This specific part number includes a 2.95-inch supercharger pulley and does NOT include a drive belt. It is intended for builders who want aggressive pulley sizing and prefer to source the correct belt separately.

Why Upgrade to an 8-Rib Drive?
As pulley sizes decrease and boost pressure increases, standard 6-rib systems often struggle to maintain traction. Vortech's 8-rib conversion increases belt contact area across all accessory pulleys, allowing the supercharger to deliver stable, repeatable boost without belt slip - critical for high-power street, strip, or track builds.
