35mm Cog Drive Pulley Package for 1986-1993 Ford Mustang 5.0
The Vortech Superchargers Cog Pulley Package (PN 8E030-028) is purpose-built for 1986-1993 Ford Mustang 5.0L applications running a 35mm cog supercharger drive. This configuration combines a 28-tooth supercharger pulley with a 73-tooth crank underdrive pulley to deliver precise, slip-free power transfer for high-load and competition-focused setups.
Designed specifically for Vortech-equipped Fox Body Mustangs, this matched cog set maintains consistent belt engagement under boost while retaining compatibility with a 4.75-inch 6-rib accessory drive for factory-style front accessories.
Cog Drive Performance Advantages
