you almost have to have get a SYE or lower your transfer case to keep drive line angles for causing problems.

Also if you are going to take it off road, you should think about a long arm kit to help you get some flex from the 4" of lift

You DONT need a long arm kit to get good flex! A 4" short arm kit will give you plenty of flex especially if you only plan on running 33's!Actually a long arm kit with 33's will give you less ground clearance! And you won't have to do frame modifications with the short arm kit!!

Check out www.4x4rockshop.com give Mike a call very informative guy good prices

An SYE is a Slip Yoke Eliminator - it gets rid of the slip yoke on the rear output of the transfer case. Most lifts (short arm or long arm) include most everything except for shocks. The length of the arms refers to the length of the control arms.

I got the Rough Country 4” lift for $530 and it included everything for a basic lift for my 2001 TJ

At some point you will need longer brake lines. You can get extensions from rubicon express or some stock lines from either an XJ or YJ (I am not sure-maybe someone else knows) If you wheel with stock lines you will most likely break them.

You will need to drop the t-case with 4” lift negating the lift, but it will work until you get the SYE/DS.

Most likely you will need rear upper adjustable control arms when you get the SYE.

Do not install the dropped pitman arm on a lifted TJ unless you have >= 6" lift. (It almost always causes steering issues, you can always add it later but I doubt you will need it.)

Don’t worry about the sway bar disco’s. How hard is it to remove the bolt and zip tie them out of the way?

My first time out with the 4” lift, dropped t-case skid, brake lines, open diffs on 33’s I followed locked rigs on 35’s. (my first time out so they took it easy on me)

Enjoy the ride and build as needed.

You may probably have to re-gear too but folks don't like to talk much about this because it can get exspensive.

What gears do you have in the diff's now?

There may still be a metal tag on your differential cover held on by a couple of the bolts. Kinda like a dog tag but it has the gear ratio stanped in it. Might read "3.07, 3.73, or 4.10." I believe only the 4 cylinder engines were sent out with the 4.10 gears.

You need to study the effects a larger tire has on your highway driving if this is a daily driver (commonly referred to a as a "DD").

As an example; if you have the 3.07 gears and you install 33" tires you'll just as well lose 5th gear on the highway. There will not be enough torque provided through the drivetrain to get you up even slight inclines with this mix.

On the trail in 4 WD low, you'll be rolling right along even in first gear (might feel like 3rd) now.

We don't know your configuration so a lot of information is missing from the equation too.

Be safe, and may God bless you. (My son did 1.5yrs in there too, Army 8yrs total) Thank you for your service also. Please take care, we can get the Jeep figured out on your return.

Provo, since you are a newb here are a couple of great sites that have helped me understand a lot about jeeping/jeeps. http://4x4xplor.com/

www.stu-offroad.com

best advice I have is research, research research. Go big and go premium with most of the mods you're doing. In the long run you will save money as you will not be doing 2 or 3 lifts, changing out skid plates etc. That's not to say there are not inexpensive mods out there, just goes back to RESEARCH!
