Trying to research these things and either im not very good at it or I cant find exactly what I want. I got a 62 series with stock axles and I was going to put 35' tires on it and was wondering if it is necessary to swap gears or is it all right to run them with the stock gears. Also the rig will have about 5 inches of lift and would the driveshafts have to be lenghten or will they be all right?
