You may or may not need all those extra parts. I had roughly 5" and had minimal mods.

Well then this is confusing I guess I should just try it and have plenty of extra money ready. I had heard all those extra parts came to play with 6"s or more but I trust all you guys you seem to know what your all talking about.

Every jeep is different.

I have 4.5 and you CAN skip the control arms and pitman arm etc... But it would extremely behoove you not to.

I also added the shackle kit and the spacers (to level the front with the rear) adjustable track bat and drop bracket and pitman arm. I wouldn't give any of those up to save money. A few extra hundred now vs thousands when something breaks...

I also had a 6" with the same set up on another xj and I would definitely prefer that for aesthetics but practicality is just fine with the set up I have now.

You can always scour online and junk yards. I actually found an entire 6" lift and bumpers for my ranger a few years ago in a junk yard but that's pretty rare.
