The U-Turn is still crossover steering that disrupts the track bar/drag link relationship unless the track bar also gets moved.
I don't honestly know what it involves but I do remember when JeepsUnlimted was still around there were a few threads of people who had installed the U-Turn and then were not at all happy with the kit. But like I said since I had a wider than stock front axle and over knuckle mod done I never looked at the kit. I just know they have it and it is SUPPOSE make the steering work with the AirRock. But I have no knowledge either way.
