I daily drive my T4R but travel to the mountains (Just recently did Alpine Loop in the San Juan Mountans, CO) so I wanted a "modest" lift that's good for highway driving and the week-long off-roading vacation.
I appreciate the nuance in your response. Thank you for your help!

I would probably put them on. You'll want them if you go any higher for sure. Just be aware that you won't probably end up with quite as much body mount clearance, but you'll have better alignment than the stock UCAs. For 285/70/17's (32.6ish height) it should clear jus fine on the mount and you'll like the driving experience a lot better with better alignment.
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.
