First if you are going to lift, then thats the time to add a front locker and regear. I had an 03 with same tires and skyjacker lift 5.5". The only time I wished I had regeared was towing and long highway trips. Also in 4 lo, the truck moved to fast and could have used regearing to slow it down hills.

If I were doing it again, I would go with 4.88 gears and a front locker. But as I said I did not regear so all I know is the 4:10's with 38" tires.

Good luck
