Underdrive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories. For example, the alternator, power steering, water pump and air compressor rob horsepower from the engine. By replacing factory-sized crank and accessory drive pulleys with a resized pulley, the accessories are slowed, resulting in more horsepower available to the drive wheels. Typically, a set of Auto Specialties street pulleys will increase horsepower by 12-15, and increase mileage by 2 to 3 MPG. All pulleys are manufactured from Billet Steel or Aluminum, exceeding factory quality.
Due to the difference in diameter from the stock Mustang pullies, the alternator and charging system may need to be upgraded if you have a large stereo system.
These ASP Mustang underdrive pullies work great on a stock or modified V8 GT or LX Mustang!

I have always experienced great service from LRS. I have had the opportunity to talk to the people from LRS on the phone and in person. The employees of LRS are true Mustang fanatics and they know a lot about these cars. They stand behind the products they sell and have always done what they can to bring them to us, the customers. I have enjoys every aftermarket and OEM part I have purchased from LRS. I will always come back and I have no reason to go anywhere else. Thank you very much.
