2003-2004 SVT Cobra 4.6L Steeda 2.81 Inch Supercharger Pulley

A new supercharger pulley is one of the easiest ways to add tons of horsepower to your Cobra in a small, inexpensive package. Steeda's 2.81" supercharger pulley is much smaller than the stock pulley on your Cobra's Eaton M112 supercharger. This pulley adds roughly 4 to 5 psi of boost pressure and generates up to an extra 60 horsepower when properly custom tuned with an SCT X-Calibrator 3. This pulley only fits 2003 to 2004 SVT Cobras with their factory superchargers.

The pulley is made out of tough, high-grade steel that can better withstand high-performance driving than more standard billet aluminum designs. The pulley is drilled around its center to lower its rotational weight. The pulley is fairly easy to install with a standard pulley removal/install tool.
