Gonejeepinat14 Anybody try balljoints yet? Will they fit on a tj?

Rsplash93 What size bse are needed for the swap from tj to jku springs. The post about the skateboard wheels. Any particular size or brand? I have aquired a set of springs and shocks off of a 2011 jku rubicon and want to install them on my 03 tj 4.0. I have read all these posts but still a little confused, will this help on lifting. I have 2in puck spacers now and 1in body lift. Can I leave the 2in puck on and still use the jku springs without having to install a sye or tc drop.

urbandork Good info! thanks for the time taken to test all of it out.

the 58s will gain you about 1.5-2" of lift in the rear but the 16s will actually loose height for the front. My brother has 18s on the front of his and he only got about a half inch of lift. I'd say get v8 Zj front springs and use those. That'll be a nice 2" lift setup as long as you do the rest of what's needed for a lift

I never noticed any Jeeps with different part numbers.

As luck would have it, I was able to get a complete set of take-off shocks & springs from a new Sahara 4dr (AT, HT) just this morning. Both front springs have the same part number (52126316AC), and both rear springs also have the same part number (68004458AA). So at least in this Jeep's case, that theory is incorrect.
I have these actual parts coming to me today. Do you know if they produced any lift?

91AzXJ This is my first post but I've been lurking around and read this entire thread over. I'm getting ready to put on a new set of 18/60 off a 2014 JKUR on my 04 TJ and am hoping for 2-2.5". Currently stock with 1" body lift. Will let you know how it turns out. I have a set of JKUR shocks on my 00 XJ with a 3.5" lift and they work great. Will see how the same type of shocks will work on the TJ with the rubi springs.

Horn5413 Doing this as we speak to my wifes 01 SE. The reason I am doing it is for the ride not the lift. I'm taking out the BDS 2.5 and Zone Nitro's because the ride was terrible and she hated it, I did also. Put 17's in the front, and the jeep is about 1.5" higher than stock. I have 55's and 58's to try for the rear. We will see tomorrow when I finish it if I can get it level with just the springs, or I do have spacers. We will see.

RubiRoad Just swapped out my stock TJ shocks/springs with the JK shocks/springs. 17s in the front and 60s in the back. Ended up lifting the front about an inch (4.0 engine, heavy bumper, winch/10,000 pound winch) and lifted the back about 2 inches. Installation was relatively simple. Leveling it out soon. Slight vibrations so I'm going to drop the transfer case an inch or two and that should fix it.

I drilled out the bushings on the JK front stocks and swapped in the stock bushings and bar pin. As previously stated. No modification on the springs. On the back the shocks went right in and I cut about an inch off the top of the back springs to make them fit over the BS cup.

Over all ride quality is night and day better. Amazed how such a cheap and simple swap improved it that much. Highly recommended mod for a cheap lift and better ride. Thanks for the tips!

RubiRoad Jeepsr4me- Did you end up swapping the JK sway bars to the TJ as well?
09-24-2014 01:27 PM
jcjeeper87 Anyone know if the trackbar should be moved?

Oregon jeep Going to install it this weekend I'll post picks just going to use springs and shocks

I wouldn't use them. They're set up for the JK's suspension geometry, mounting points, etc. You'll be fine with the stock arms. Won't be any noticeable improvement trying to shoe horn on the JK arms.

09-21-2014 01:37 AM
Oregon jeep Going to give this a try picked up springs shocks upper and lower control arms from a jk rubicon to put on my 04 tj for $100 on Craig's list
08-27-2014 08:35 PM
jdecker88 Now this is interesting. So a jku mod can be cheaper then the zone or bds lift just have to replace the spacers. But it must be jku springs correct and not just regular 2 Dr jk springs? I like the idea of using oem since the springs would hold up better then cheaper lifts

Couldn't tell you. The smoothness of the ride is largely determined by the shocks as well as proper tire pressure. FWIW, the JKU shocks are intended for a vehicle that is quite a bit heavier than a TJ. My Old Man Emu N66/N67 Nitrochargers are very comfortable on the street.

And nearly everyone, even if they find the correct JKU springs, needs spacers. In the end, you are saving money for more hassle. Maybe it's worth it.

Unless you find yourself lowering the front track bar, never ever install a drop Pittman arm on a TJ. Doing so will result in bump steer and poor handling.

Stewarts06tj No, pitman is fine. Careful though the only problem I had with the whole thing was the front rake
04-03-2014 12:05 AM
ldluckman Did you have to change pitman arms or anything else? I recently bought an 04 TJX and a set of JKU springs and as soon as I can buy some shocks I will put them on.
04-03-2014 12:02 AM
ldluckman just scored a set of JKU springs for my 04 TJX did you have to change to a longer pitman arm or use stock?
03-26-2014 11:51 PM
Stewarts06tj I have several boxes from qtec on the way I'm keeping the jkr shocks. But I'm not a fan of spacers, so I decided on ome f/r springs jks discos front and adj in rear, extended brake lines and bump stops.
The whole thing was really just an experiment. I hope after I get this all together I will have a capable 4x that I can dd without dropping thousands on complete LA's. Or huge tires

in the rear maybe a little, but the front would probably lose lift, i have the 18's in the front and it only gave about 1/4 inch lift, so i needed a spacer

Brit Nick I just bought today 18/59 springs, and a 2" leveling kit. Just looking for shocks now
Thanks everyone for all the great advise and input
02-18-2014 07:38 PM
Stewarts06tj Also as a warning. The shocks are longer. after testing I found that the bump stops need to be extended at least 1.5 and if you want any travel at all you must use the springs, a bb, or aftermarket lift springs. I'd say up to 3.5 would work.
02-18-2014 07:34 PM
Stewarts06tj Yes Brit, jk springs fronts are direct with little to no lift but ride great, rears require cutting off 1.5 on top to fit but will take you up 2 to 2.5 depending on the number springs you get. Gotta do your research, here and jeepforum have several threads. My suggestion is to use the jk shocks, prefer Rubi. With 2.5 after market springs like ome or rancho. Your pref. cheep lift rides great! .
