Ford Racing Underdrive Horsepower Pulleys increase available horsepower to the rear wheels by decreasing the load required to run your engine accessories! Not only will you see a horsepower gain when you bolt a set of these pulleys on your Mustang, you will also slow down the water pump which helps prevent water loss through the radiator cap at high engine rpm.
