I run a UCF highest clearance tuck. But it's on my 2005 auto. I don't know what the hangup is with your year automatic Jeeps. Personally, it's the best offroad performance mod I have ever done.
If you don't know, a tuck is a project. Worth it, but a big project. Not a bolt on and go affair. Clearancing the tub and moving small appendages out of the way. And redrilling mount holes, etc. Fit, refit, etc.
I'm no pro but it took me a few days to get it right on my 05' TJ. Welding was involved.
If your jeep is a daily driver, it will take some serious planning.
