A new performance product for the 2007-08 Shelby GT500. This Auxiliary Idler Assembly is designed to provide maximum belt contact of the supercharger pulley, thereby decreasing the amount of belt slippage in high boost situations.

Features All components are CNC machined from 6061 T-6 aluminum for accuracy and detail.

Billet Idler Pulley is "Hard Coat" anodized for superior belt wear protection and bearing bore hardness.

Same brand and grade, sealed for life bearing as used in the OEM Idler Pulley.

This Auxiliary Idler is needed when using a smaller supercharger pulley on your Shelby.

This will allow you to use the stock belt when using a smaller supercharger pulley. Works with 2.8 and 2.6 S/C pulleys.
