I like the single spring idea better as well, plus I have a few TJ springs left over from lifting my dadÆs Jeep. My new 5" superlift rear springs now lift only 3 1/2" so this would be a big help. Would the rear axle housing be strong enough to weld just a mount on top instead of welding a truss across the top of the housing? Also as a thought, the ACOS adjustable coil spacer would be nice to mount at the top if you could only get just one of them instead of a pair. That way, you could fine tune the rear end.
