I dunno. You can still fit a sheet of paper under the diffs...
Reminds me of a tandem axle 18' trailer I used to haul for a place I worked years ago. When fully loaded, it got a flat on one side, and I couldn't change the tire and tried to limp home on three tires with the ubolt on the axle scraping the ground now and then. I had to cross some RR tracks, and oops if it didn't get hung up on the track! Not wanting to get run over by a train, I had to jack up the axle enough to pull forward off the jack enough to clear the track with the ubolt...
I hope mr slammed jk doesn't get hung up on the tracks. Probably not, though, seeing as how the wheels aren't much smaller than the tire diameter.
