Underdrive pulleys unleash horsepower by slowing down the accessories your engine is running. These do not "Make" horsepower, they simply "Free Up" horsepower. You should run these with a Cold Air Intake and some Exhaust mods. You do not want to run these on supercharged cars. We offer Mustang Underdrive Pulleys from BBK, Steeda, and Roush. Shipping is free on every order.
