Well, The problem i have noticed is one thing hindges around another. Want a lift well after the lift you need a short shaft kit for the transfer case and new gears depending on what size tires you run. Get bigger tires and start doing some challenging things well the front steering will fold like a pretzel. See how beefy my steering system is? Folded my stock tie rod into a u shape. Bumpers, lights, winch, stereo, cb, etc are great mods because you can just install them. Once you start lifting etc. you start exposing the other week links of the stock jeeps. There is a mod for the rubicon that i have read about that can be wired to throw you locker on when in 4 hi which is nice. 4 lo only kind of sux.
