portal axles are some impressive stuff. There's really no other way to get that much clearance per tire size. Without them, no matter what kind of lift you get, you'll still only be able to get an axle clearance of (Tire Size / 2) - (Diff Size). A portal axle can raise the axle up 8" or so just like that!
That being said, if I were going to be doing a portal axle conversion, it wouldn't be to a KJ. I like driving my KJ on the road, and I don't think there's any way to make one of those portal axles road-friendly. I bet that land rover is pretty nice though! (if you're on a safari or something)
One of the first sites you find when you search for unimog you can see a mog climbing straight up a 30" concrete step. Impressive!
