I am getting this 4.5 from RC what all other mods will need to be made? http://www.roughcountry.com/jeep_xj_4.html
Also what does it mean by the trasfer drop? I am new to the whole lift thing. With this kit on a skill level of 1 to 10 how hard is to to put on? ( i am some what decent with a wrench) just never really tried anything like this.

 

best advice i have for you is 2-3 days before you plan on starting your lift go and pb blaster every bolt you even think you might come in contact with. Do this a couple of times and it will save you a bunch of headache

 

transfer case drop is exactly what it says a transfer case drop. it takes care of driveshaft angles so it doesnt vibe.

 

sorry to thread jack but ive noticed that the 4.5 RC kit doesnt say anything about an adj. tracbar. does anybody know if it actually comes with it or if you have to buy one extra? to add to what else you need if it doesnt come with the adj. trac bar you need it

 

You are going to need to do something about the track bar...And the brake lines are going to be addressed.

 

What do you mean PB blast? How had is it to drop the transfer case? Will i need a new track bar?

 

I did my 4.5" RC kit over a weekend taking my time, could have been done in a day if I didnt spend so much time drinking with my buddies who were helping me. PB blaster everything you'll be taking apart for a week b4 doing it. be prepared to snap your rear upper shock bolts, once snapped hammer the nuts out from the bottom (just tac welded in there) drill them out with a small bit to give you a pilot hole on top then drill a 9/16" hole through the floor (was behind the rear seat on my 2door) so you can slip a bolt thru and still get a socket on it, slap the nuts on from the bottom and that takes care of that. get the trac bar and a drop pitman arm too. when doing the t-case drop RC will tell you you can take the studs out with a jam nut (BS) do it with a pipe wrench (much easier) good luck

PB Blaster is a penetrating lubricant... dont buy wd-40 it doesnt penetrate

 

on those shock bolts mentioned in the post above this, I just used an air hammer to knock those out, then used a telescopic magnet to fish a bolt up through those large triangle shaped holes next to your up shock bolts, and dropped em through the holes where the nut used to be. just put the shocks on and put a nut on it.
