Hey all,

I have searched through our forums here for lifts on XJ's and there doesn't seem to be a in depth discussion of "issues" that should be addressed before hand.

I would like to put something like the fabtech 4" performance lift and 32" tires under my XJ.

What I would like to do is take all of your answers and put together a guide that lists the general issues everyone seems to run into when installing a lift kit.

That way it benefits any/all newbies and not just myself.

Some things I have read about that I have questions on:

At what height of lift do I have to:
- install a transfer case spacer?
- lengthen driveshafts?
- install a drop-pitman?
- install a longer trackbar?
- change transmission linkages?
- install longer brakelines?
- consider longer track arms?

What are the pros/cons of using AALs vs. new springpacks?

At what tire size should I consider changing my diff r+p and to what ratio?

What are the problems people have run into other than these?

Just from my experiences.......

At what height of lift do I have to:
- install a transfer case spacer?
Probably, if you have a 91 or newer xj you will need an SYE (slip yoke eliminator)/drive shaft....pre-91 you can get away w/the case drop at 4" and lower
- lengthen driveshafts?
See above
- install a drop-pitman?
Not quite sure as mine already had one when I went from 2.5 to 4.5"
- install a longer trackbar?
Would be a good idea - an adjustable RE worked for me
- change transmission linkages?
No
- install longer brakelines?
Yes, and you will probably have to relocate your E-brake lines (if you use it)
- consider longer track arms?
When I first put my 4.5" RE lift on, I didn't, but when the bushings in the stock arms gave out, I went to Rusty's arms for 4.5 lift....waiting for $$ to get adjustable arms

What are the pros/cons of using AALs vs. new springpacks?
I think its mainly personal preference....saying that, I prefer the full spring packs

At what tire size should I consider changing my diff r+p and to what ratio?
the stock gearing was liveable when I had 33's, but when I got 35's I knew it was time for a change....went to 4.56

What are the problems people have run into other than these?

Most of this depends on how you use your rig. Then you have to decide what is right for you. There is not a one guide fits all answer. Safety issues are a no brainer, and a daily driver has different issues than a trail only rig. I know this doesn't help much, but in the end its your choise that matters. I am sure my use and driving habits are not the same as everyone else. Try Naxja.org for more XJ specific info.

Mr CDhowell makes some very valid points..


In most cases, a 3.5 inch lift and 31's is a good foundation. Rubicon Express has a great starter kit in the 3.5 inch lift range. Being that you have a 95 you may not need a slip yoke eliminator for your transfercase. you will need new shocks though. I suggest a full leaf pack over an add-a-leaf. Over time the Add-a-leaf will break down the main leaf and begin to s curve your leaf packs due to axle wrap. A 3.5 inch lift, some skids and a posi or locker will provide you ample trail duty as well as Daily driving duties for many years to come.
Unless of course you get bit by the bug and go from 3.5 to 5.5 in a matter of 6 months, like I've seem many new comers do..
