I am considering buying an F150 Ecoboost crewcab 6 1/2' bed to tow my ski boat. I have looked at one with the 3.31 differential. The combined weight of the boat and trailer is 4500#. Will a 3.31 meet my needs or should I go with a 3.55 rear end?
Maybe this will help explain: Understanding Axle Ratios | Pro PickupCan someone actually explain these ratios. The little that I know is that the lower the number the better the fuel economy. Why would the ratio affect towing?
Thanks for the link. It explains a lot. Read it 3 times.Maybe this will help explain: Understanding Axle Ratios | Pro Pickup
