I would take the 8.8 vs the super 35. As for the front 30, you can run 35's on it just fine,, I would however get a selectable locker as that will help to limit the stress on it in 4wd If you did find a HP 30 from an XJ for cheap I would pop that in there as it will beef it up a bit. The super 30 kits is nice too. I would carry some spare ball joints with what ever option you go with. Confused yet? LOL good luck with what ever you go with!
