Well got the lift installed. Took it for a drive and have vib issues... so much for good luck lol. Havent installed the RE gen 2 quick disconnects yet. Heres some pics.

 

Definetly pick up a trackbar if you need it! I just installed mine a month or so ago. Yes it's a rustys, they improved the quality over the years. Thing is beefy as hell! Love it

 

yeah its on the list. want to get all my vibrations taken care of first. I should've known I was gonna need an sye but **** happens

 

Dude, I just got vibes when I went over 5-7in. I have a 1in tc drop. I have a set of 6* shims to throw in. Waiting in another rustys delivery Monday for some odds and ends. Trying not to sye, with a 3.5 a tcase drop should be fine. But everyone's Xj is different.

If I have to sye, my wife's gonna cut my ***** off. But, you pay to play.

 

I got a 4.5 and my leafs allready had the shims on the from RC. they are 6*. along with a 1" tc drop and no vibes at any speed.

But i agree everyone is diff.

 

Some jeeps are really picky about this.
But I agree with the other guys. Sye isn't your only option here by a long shot.

Drop kits are under 30 bucks and that alone should do the trick for you at 3.5

Keep in mind when/if you install the tcase drop: There is one bolt and one stud on each side of the cross member. You will need a stud extractor/one handed pliers/patients to get the studs. You can also use two nuts on the stud to get it down but that didn't work for me at all. You can't just pull the studs down through the slots in the cross member when you do get them loose.. They need to go up and out due to a burr on the top side of the stud. So you will need to be able to have the side your working with far down enough to accomplish that. Have a jack handy to support the cross member too. And do one side at time. Take your time and don't strip anything.

I wish I had that info before I did mine and found out the hard way about the studs. Haha

 

FKNG XXX a million.
Been there. i tried the 2 nut thing also. The stud broke. drill and easy out worked.
get some PB blaster and spray them up.

 

Yeah those studs were a pita. I used the two nut trick and it worked fine. Installed a make shift drop kit I made with flat bar, its ugly but it kinda worked. ill find out what the tire shop says about my pinion angles and go from there. Feels damn good to have a lifted jeep again. I appreciate all the tips
