By all means re-set the caster if it changed as a result of the lift. In most cases it should be OK, but if you installed longer shackles (such are supplied with the Rubicon Express kits) at the same time it will reduce your caster. The longer shackles drop the front of the spring, thus tipping the caster angle down. Don't use aluminum shims, they'll wear quickly and eventually split in half and get spit out. Use steel shims of the type that are held in place by the spring pack centering pin.

The best fix is to cut the spring perches off and weld on a new set with the caster dialed in. However, this is a big, expensive job and steel shims will do the trick.

The biggest thing I noticed after a 2" lift was flat towing. It didn't turn as easy as it did before the lift and wouldn't straighten out right away. I added a 2 degree shim and now is back to normal, follow's correctly and turns and returns straight as it should.

Noah, that's a nice color rig you have there my friend. Mine is flat green as well, but a much more drab green. I like yours.
