35mm Cog Drive Pulley Package for 1986-1993 Ford Mustang 5.0
The Vortech Superchargers Cog Pulley Package (PN 8E030-027) is engineered specifically for 1986-1993 Ford Mustang 5.0L applications using a 35mm cog supercharger drive system. This package pairs a 27-tooth supercharger pulley with a 73-tooth crank underdrive pulley to deliver precise, slip-free power transmission in high-load and race-oriented setups.
Designed for Vortech-equipped Fox Body Mustangs, this cog pulley configuration provides consistent belt engagement under boost while maintaining compatibility with a 4.75-inch 6-rib accessory drive for factory-style front-end accessories.
Cog Drive Performance Advantages
