If you intend on wheeling it rather frequently in Utah trading it in for a Rubicon Unlimited would be your top priority. No actaully that's an inside Zutah club joke. Sliders are top priority unless you can care less about body damage because you'll get plenty of it no matter how good of a driver you are. If you have an Auto Trans I would go with the Tera-Lows due to the lack of ability to back up over obstacles. If you have a manual I would go with a locker (rear locker, that is unless you can find a selectable front locker). You know oddly enough I happened to have 2 sets of sliders (one DOM 2" x .120 & one 2" square) about 90% completed that just the other day I was telling someone that I would be willing to give them away, but then again I would have to actually meet you. Being that this hasn't happened in the 3 years that I have known of your exsistence they will probably be still sitting in my garage come winter.
