      1 Top Rated Question

      How much towing power will I gain by changing from the 3.42 gear to the 3.73 gear?

      • Changing gear ration does not change your power, it simply allows for the ability to reach the top end of each gear faster, which typically means your driving faster. This is a mechanical change however, so this will not be changing any HP or TQ numbers.
