you retard, ground clearance comes from bigger tires, not the lift. your diff's will be the same distance from the ground with 33's and 3 inches as it will with 33's and 6.5 inches.
While I'm all for LCOG jeeps, I don't think it's quite that simple.
On really deeply rutted trails, in deep mud, and in deep snow, the clearance under the diffs/axle tubes is definitely the most important factor. If you get high-centered on both axles, it doesn't matter how high the jeep is sitting above your stuck axles.
But, for going up ledges, big rocks, etc., the clearance under the body between the two axles is going to be the most important factor.
So, really, it depends on the kind of wheeling you're doing, as far as I'm concerned. You really need the big tires and the big lift to do it all well. Of course, your jeep will be a rolling deathtrap on the highway unless you've got a ridiculously wide stance, and heavily upgraded brakes and steering. Either way, you're spending a crap-ton of money that could have been spent on gas to go on more wheeling trips in your cheap jeep, and maybe a winch to get it unstuck.
