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.
***NOTE: Requires Shorter belt.*** Following are gates part numbers and are for vehicles equipped with A/C And Smog "or equivalent eliminator pulleys"

Well me and my girlfriend had a day off and decided to take a road trip to Late Model Restoration. Let me tell you, we had the best CUSTOMER SERVICE ever. Jay was very helpful and knowledgeable about the parts I purchased. The showroom was clean and inviting. Also I got to meet JMAC that host's all of their YouTube videos. They also had project BLUE COLLAR in the parking lot, and it is NICE. I will recommend Late Model to everyone I know...
