07-11 Shelby GT500 Auxiliary Idler Kit for Kenne Bell Applications


This "Shelby" engraved auxiliary idler kit was designed for GT500s using Kenne Bell superchargers and engineered to be a simple bolt to be the ultimate solution to belt slippage.

The kit consists of a heavy-duty, precision-machined aluminum plate and a billet 90mm idler pulley.  The plate bolts to existing bolt bosses on the vehicle and locates the pulley just to the left of the supercharger pulley, maximizing belt wrap and eliminating slippage.  No modifications to the vehicle are necessary.  The required fasteners are included, as well as illustrated installation instructions.

• 2007-2011 Shelby GT500s using a Kenne Bell supercharger. Will not fit Whipple for factory GT500 supercharged applications.
• Includes black-oxide coated mounting hardware.
