2007-2012 Ford Mustang Shelby GT500 Supercharger 5.4L Eaton M122, w/ 2.6" Metco pulley. In great shape, Came off my 2008 GT500 with 30k miles. Spins free and performed flawlessly when I removed it and upgraded my blower. Please ask any questions or for more pictures before buying. Just don't need it taking up space in my garage. Thanks for looking.
