Should i swap my 3.42 gov lock diff for a 3.73? If so, how difficult/expensive would this be?
I do light towing occasionally and drive on the highway most the time. I just feel like my truck is sluggish and not at its full potential. I care about highway mileage as per why im not really looking into the 4.10’s. I might consider putting bigger tires on it but im not sure. Its my daily driving truck so will be driven a lot.
