There are a number of accessories that are added onto your vehicle designed to allow the vehicle to run well and to improve the driving experience. These accessories include the alternator, your air conditioning compressor, and your power steering pump. These accessories run off of belts from your engine, and they have a rather parasitic effect on your power. If you have a Ford, one way to reduce the parasitic effect of your accessories is to install a set of Ford Racing performance pulleys. Ford Racing performance pulleys are designed to gear down the accessories by using a larger rotational pulley. The Ford Racing performance pulleys will still provide your accessories with all the power they require, but they will actually slow down the engine speed necessary to power them. These larger pulleys are lightweight, which reduces the rotational mass that needs to be spun, improving your performance. Because they are manufactured by Ford, you can be certain that your Ford Racing performance pulleys will work with your OEM parts. Installing a set of Ford Racing performance pulleys will require a different sized set of V or serpentine belts.
