My main thoughts were about the drive shaft and axles and will upgrade to the steel planets. Currently using 1/2" wheel studs. If i upgrade to 5/8", would that require new wheels as well? No, you should be able to enlarge the stud holes in the wheels slightly for the bigger studs. That's what I did w/ my Centerlines.
