Chevrolet Performance idler pulleys are a part of the accessory belt system on the front of the engine. These pulleys are a GM recommended replacement part for your vehicle's original component.
Pulleys can be ribbed or smooth and contain a sealed ball bearing. These idler pulleys are used to divert the drive belt to the components such as the alternator, water pump, or power steering pump.
Chevrolet Performance idler pulleys have been manufactured to fit your GM vehicle, providing you with the same performance, durability, and service life you expect from General Motors.
