It is impossible to say. I had to do a 1"TC drop with only a 2" BB.
Install the coils and shocks and determine if you need to do the TC drop.

You may want to think about a 1" body lift and a motor mount lift. If your putting all the money and work into getting lift the last thing I would want to do is lower the transfer case unless you have to. Plus if you do a MML you can do a tummy tuck and get even more room under your jeep.

And with a MML it helps with driveline vibes. So you might not need to drop the tcase

That's pretty sweet. If I ever decide to lift the TJ, I know what I need now at least for a cheap lift.

Looked online and theres a set of 2011 Rubicon springs/shocks for $50.....very tempting......

To the OP, Im very interested in this lift, however many people seem to be saying that it would never work. What trim JKU did you use the springs/shocks out of? Did you really manage 3" of lift? Also, was the TJ a sport or SE model?

What? I did not mess with mounts. Reread what I posted. Should get it then.

I am still around. Just had to take a beach break. Drove the Jeep the whole time. I have a 4 banger SE model and I got about 3 inches give or take. My old junk had 150k of hard miles on them so there could be some lead way in the lift amount.
i did it to prove it could be done. And I did. Shocks work out great. And they are every where CHEAP. I picked up another complete set of JK junk. Not sure I am ever going to need it but, hell Did not think I would need that other stuff 2 years ago.
The springs i got where from either a 07 or 08 Sahara 4 door. Numbers on them where posted. the spring is thicker and I assume higher rated than stock TJ stuff.
I listed plans on how to get them under you junk. I dont post much. But what i posted is right. As for pictures I was screwing around trying to edit in some stuff and deleted everything. And I dont have them on my computer anymore.

I used a vice. Took larger deep well socket and pushed it till flush on one side. The used the vise to grab a hold of the bracket and I spun the shock and wiggled it free. Hammer does not work. You will just F up the bracket. If you dont have vice bigg enough a High lift jack will work. Its basically a big vice. If you dont have that a real shop press will do it in a few seconds. If you dont have either of those, go get one. U will use it millions of times later.

Getting the JK sleeves out you do same as above but put a socket that is smaller than sleeve on one side to push the sleeve out. I think they make the sleeve and bushing together so very hard to get started coming out. May even start pushing the rubber bushing with it. I just turned the larger deep well socket around so the 1/2 ratchet hole was holding the rubber in place till the sleeve started moving. Once it starts it goes easy if sprayed with lube.

Getting them back in is a pain too. The flat part is wider than the hole you trying to push it into, just have to slowly get started with a light coat of lube. I had one that had some sharp corners so I ground those off. Made sliding in easier.

I hope this helps clear that up as I only referred "to press out those pieces" in my instructions.

I've got a friend that just lifted his 2008 X and I can get the springs and shocks really cheap. I'd like to see some photos as well to make sure I'd feel comfortable with my skill level doing this cheap lift.

Thanks!

to answer the spring question: JK's have no set springs I have hunted and read hundreds of tags and they change all over the place. I've seen 4 door HT Rubi's with 15s up front and 58's in the back best bet is just to order the highest rated springs from chrysler direct.

No best bet is to TRY what you can find CHEAP./ Cause you really got nothing to loose. The shocks are worth what most pay for whole complete suspension from a JK. Hell mine were FREE......

I just removed my stock TJ springs and 2" BB and installed JKUR springs up front thinking I'd get 3" of lift like the OP and I actually lost about an inch and a half.



Attachment 113355

Before with stock TJ springs and 2" BB



Attachment 113356

After with the JKUR springs with the last 2 numbers being 18.

If you're wondering why the rear is the same height, it's because I didn't even bother with putting the rear coils in after the results I got with the fronts. Even though I feel like the rear might have actually netted me some lift since the diameter of the spring itself is much thicker than the stock TJ rear spring. But when I did have the JKUR springs up front and still had my shocks disconnected I bounced the Jeep up and down to feel how they felt before I put my original springs and BB back in, and when I did put my stock springs in I once again bounced the Jeep and there was quite a bit of difference in the stiffness. The JKU coils are longer than our TJ coils but the spring rate of the JKU is softer than our TJ's which is why I didn't net any lift and actually lost height. And I know that the JKUR springs I used weren't old or sagging because they had less than 10,000 miles on them and I sold them to a guy in a 2 door JK X and asked him to tell me how much lift he got if any and he told me that he got about an inch out of those springs compared to his 2 door X springs. Also with the stock TJ spring rate that's why over on the AEV forum a lot of guys are actually using TJ springs to gain an 1" to level our their rig after adding an aftermarket bumper and/or winch. Here's a pic I took of the JKU spring next to the stock TJ spring.

Attachment 113684

Might be hard to tell in the pic but I lined up the bottom of each spring with the crack in the concrete.

I would be interested to know what the spring perch to spring perch measurement is on the stock JK. This would give a reference for any lift.

I just picked up a set of 59 rears. Hope to have them on on tomorrow. This should give us some idea how the rear spring will measure up.

Yeah I feel like the rear springs would actually lift the rear some. I know theres a guy on JF that uses some ZJ V8 springs with spacers up front and JKU springs in the rear for a 3.5" lift. Hopefully you have more luck then I did. Don't forget the pics

I finally got the rear springs in today. They set 1.5" lower then the 3.5" re springs I had on the jeep. The re springs gave me about 4.25" of rear lift over stock, so the conclusion is you should gain about 2.75" of rear lift with the jku 59aa springs on the back.

I installed JKU Sahara shocks on the front of my TJ. They are around 1.5' longer than the stocks TJ shocks fully extended.

Like the OP said you need to press the bushes from the JK shocks in order to install a pin from you shocks. If you still have the stock TJ shocks like I had then you will need to cut the bracket open and cut the rubber bush from the pin as they are fused together.

The ride now is much better and the best of all is they were free.

Did you put the rear JKU shocks on as well?

I have new Zone Nitros for the rear that I bought couple of months ago when my old ones started leaking oil. Apparently the rears bolt right up without modification.

Yeah I have 4 JKU shocks with only 13 miles on em on the way along with bar pin eliminators since my current front lower shock bushings have seen better days. I can't wait to see how the ride is with all 4 JK shocks installed.

The bar pin eliminators are not available over here so that is why I pressed the pins from my existing shocks into the bush on the JKU shocks - a little bit of work but works like a charm.

Okay, guys- I registered here to also report that I installed my 2012 JKU (17) springs in the front of my wife's 2004 TJ with 4.0/Auto and I lost almost a full inch over the stock springs. The springs came out of my JKU Sport (with auto and soft top) with under 3,000 miles on them. The shocks are working out great (I ground down the lower sleeves instead of messing with the brackets) but it appears the front JKU springs will ONLY provide lift on a 2.5 liter, 4-cyl Wrangler.

The difference from one JKU coil spring to the next is minimal. You can analyze all you want, but at the end of the day you'd be hard pressed to know one from another once installed on the Jeep.

What were the numbers on the JK springs? I'm curious to see if they were the soft or stiff ones, knowing that you lost height maybe its due to them being the soft ones.

That was the (17). Again, the difference is very minimal and could not possibly make the difference between one inch lost and three inches gained.
