I didn't have the clearance issues until I jumped up to 285/75/17 (34" height). At 3" lift up front I definitely wanted the JBA UCAs. Overall they worked great. At stock height you'd move the LCA back far enough you might have body mount clearance issues, so I wouldn't want the JBA arms at stock or near stock height.

I'm keeping them in case I end up keeping the 4R and lifting it higher again. I mess around with it a lot - it only takes me a maybe 2-3 hrs to re-adjust the front to 3", swap UCAs, swap rear springs to some 2.5" lift Dobinson ones I have, and then re-adjust alignment pretty close to where I want it. Keep track of your alignment cam locations at each height and it's an easy re-adjust back to proper alignment when you want to switch around. For now with a 2yr old - my trips are more Yellowstone and Glacier with my camper, and less Moab and Rubicon.
