VMP-90-S-B 90 mm Heavy Duty Billet Aluminum Idler Pulley

Description

A great upgrade to the factory idler pulley, the VMP 90 mm idler pulley uses a factory size and brand NSK heavy-duty bearing. When the proper sized bearing is used, the need for double bearings is eliminated. Easy to install, the VMP 90 mm idler pulley can be installed in just a few minutes in your garage. Made in the USA, with durability in mind, our 90 mm idler pulley is constructed of Billet anodized aluminum. Fits these applications/situations: 2011+ 5.0 L Mustang GT with Roush, Whipple, and VMP Superchargers (some filing may be needed due to core shift in the bracket for the idlers) Other applications that require an idler with 17 mm bore Can be used with 2.4", 2.5", 2.6", 2.7", or 2.8" supercharger pulleys on a 2007-2012 Shelby GT500. This idler helps eliminate belt slack and gets better wrap with smaller supercharger pulleys Roush M90 and P51 TVS blowers when installing a smaller supercharger pulley, install below the supercharger pulley Note: On a GT500 the idler pulley should be installed below the intercooler tubes, to the left side of the blower.
