Hate to be the bad guy in this one, but..................
The oro uturn is a very poorly designed and overpriced steering system.
It will reduce your turning radius, eliminate proper ackerman causing poor return to center and tire scrub.
The draglink is a poor design, which is why its on its 4th rendition.
The tie rod ends they use are rare, small, and weak.
The reason Bears draglink is holding up is because he runs hydro assist, essentially removing most the load from the draglink.
Unless you are picking up a used version for a couple 100 bucks, I wouldnt recommend the uturn.
Dom went through close to a dozen draglink tie rod ends before he gave up on that system and had me build him a true histeer crossover system using 3/4 ton chev TRE's.
By far the currie system is the best off the shelf hd steering system for a TJ.
The ZJ "upgrade" is a hoax, and shouldnt be considered unless its free or a 40$ wrecker find. Otherwise you might as well weld a peice of angle iron to the stocker to re enforce is slightly.
