Hey, I was wondering if anyone has used any underdrive pulleys on their sport tracs. Is it worth it and how do you know what belt to get? I was looking at the Zabteck pulleys. If I were to get the pulleys for the alternator and the water pump would it have any effect on the horsepower gains from using the underdrive crank pulley? Thanks
