2003, 2004 SVT Cobra 4V 4.6L
Billet Flow Non-Slip Interchangeable Blower Pulleys
Hub + 1 Pulley
This interchangeable supercharger pulley from our good friends over at BilletFlow comes is a wide selection of sizes that can make you huge amounts of power. These pulleys have smaller diameters than their stock cousins and allow the rotors within your factory Eaton supercharger to spin faster and throw more air into your engine for massive power gains. These pulleys fit the stock M112 Supercharger of 2003 and 2004 Cobras as direct swaps with your factory pulley.
This BilletFlow supercharger pulley is available in three sizes available from our drop-down menu: 3.100", 2.930", and 2.760". Additionally, there are red, blue, and black color options available. In general, these pulleys offer the following boost levels:

Each pulley hub is precisely CNC machined from 4150 prehardened steel, while the actual rings are manufactured from 6061-T6 billet aluminum and receive your choice of anodized finish. The pulley comes with stainless steel screws and lock washers. The pulley requires a pulley-puller and other tools for proper installation.
