Steeda Supercharger Pulley
Upgrading your 2007-2012 Shelby Mustang GT 500's supercharger pulley is a convenient and affordable way to get a lot more power from your 5.4L V8. Steeda's in-house testing has shown increases of over 125 horsepower and 100 ft-lbs of torque when this pulley is used in conjunction with Steeda's 2007-2009 GT 500 Cold Air Intake.
Steeda's GT500 supercharger pulley is a direct replacement of your factory supercharger pulley that adds about 3 psi of boost. It is made right here in the USA from billet steel for outstanding durability and plated with nickle for show quality style.
