VMP Performance 07-14 Ford Shelby GT500 Belt w/ stock or 10 Percent OD Lower

This is slightly shorter for use with 10% OD balancer only, and smaller blower pulleys (2.5" and less) with no idlers. Belt also works with stock balancer, stock idler and 2.5" pulley on 2007-2012 GT500. If you have an aux idler or a larger blower pulley you need the K100852 belt.
