This Set of ASP Silver Aluminum Underdrive Pulleys (824125) reduces the amount of power needed to drive external engine accessories, such as the alternator, power steering, water pump and air compressor. By slowing external engine accessories, these pulleys are typically able to create horsepower gains of 12-15 and increase mileage by 2-3 MPG. These pulleys will help you get the most out of your 1979-1993 Mustang's 5.0L engine.

Slowing external engine accessories can be achieved by replacing your factory-sized crank and accessory drive pulleys with resized pulleys. This, of course, results in more horsepower available to the drive wheels. The pulleys in the set are made of premium billet aluminum coated in a silver finish. They even exceed factory quality!
