Most of today’s vehicles use Idler Pulleys to assist in belt routing and tensioning within the accessory drive system. Air conditioning compressors, alternators, power steering pumps, and water pumps are aided by the function of Idler Pulleys. All Idler Pulleys are of the highest quality and meet or exceed OE specifications.

Vehicle manufacturers often use several sources for Idler Pulleys on a particular model. For that reason, the replacement pulley supplied may not always look like the pulley being replaced. In these instances, the supplied part will fit and function to O.E. specifications.
