Adding a set of Steeda underdrive pulleys to your Mustang is a great way to free up extra horsepower and reduce strain on your accessory drive. These pulleys slow down your accessories about 25%, reducing the drag on your engine, which allows you to make more power. Each kit includes a direct replacement underdrive crank, water pump, and alternator pulley. These Steeda pulleys are specifically tuned for the 4.6L engine and are the only one of its kind on the market. Pick up a set for your 1999-2004 Mustang and give your motor a little more horsepower!
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
