Auxiliary Idler Kit with Extreme Duty Double-Bearing Idler Pulley

2007 & Newer Shelby GT500

Fits Eaton, Whipple, & VMP Gen II TVS Superchargers

The Metco Motorsports auxiliary idler 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 serves as a bullet-proof mount 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 ider assembly ships fully assembled, and the required fasteners and illustrated installation instructions.

When this kit is installed with our popular MSP2.60 supercharger pulley (, a belt that is the same length as the original can be used.

Note 1:  Image 3 shows installation of the single-bearing idler kit.

Note 2:  Will not fit with 4.0L Whipple supercharger.

Price: $219.99
