Evolution Shelby GT500 Dual Bearing Auxiliary Idler Extreme Duty


The Evolution Performance, Inc. Black auxiliary idler Extreme Duty True Double-Bearing Idler Pulley kit for the Shelby GT500 is cleverly engineered to be a simple bolt on and to be the ultimate solution to belt slippage.

The kit consists of a heavy-duty, precision-machined aluminum plate that offers three locations for the included 90mm double-bearing 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.
