I plan on regearing and putting e-lockers lockers in. When I call to get quotes for 5.13 a lot of the places recommend 4.56 or 4.88. I currently have 33's and when I go 35's I will be putting in chromoly axles at the same time. I feel a little lost in all this. I have the 4.0, nv3550, Dana 30/Dana 44.
