Yes I plan to do the install my self. I'd really like to do a 4in if possible
I really wanted a 4" lift when I bought my rubi. After having it on for about a year, ripping it off to go back to stock suspension, then finally now having a TF leveling kit. You will be so pissed at your self if you buy a less expensive 4" lift. They are very incomplete and cause more steering problems then it is worth.
I ran for over a year with bushwacker flatties on stock rubicon suspension, before I put my TF leveling kit on. Low COG is best for on and offroad use.
