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?

jcjeeper87 Anyone know if the trackbar should be moved?

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.

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

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
04-02-2014 11:05 PM
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.
04-02-2014 11:02 PM
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 10:51 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 06:38 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 06:34 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! .
02-18-2014 06:26 PM
Stewarts06tj Finished last night, details in my previous posts. Bar pins were by far hardest part. Heat them up and push them out! 2.5 rear 1.5 front with spacer! Wtf! Not what I expected. I like the stance though looks good with my 245 75 mtr's too. Rides amazing with no driveline vibe or alignment issues. Will update as they settle and I'll add pictures tonight.
02-18-2014 12:03 PM
Brit Nick Just to throw something else out there.
Do you think aftermarket JK springs would work also ?
02-18-2014 08:10 AM
1Felix1 Well I have more info. I have 2 1/2" of lift over the stock configuration. I measured a friends stock 2002 TJ last night. He has 31" tires just like I do. So I think I'm pretty sure of my measurement. I should have my ATB's by the end of the week. I will update.
02-17-2014 08:26 PM
brandon-99tj Rubis came from the factory the height as all other TJs, they just had 31" tires. So without knowing more about the other rig, we cant tell you how much lift you got.

I'm sure you'll get more in the front with the 18 springs, but if you could find the 19 springs it should be a little bit more lift. With the jk shocks added as well it rides very nicely.

Same setup as me but I have a 2000. I installed the springs and shocks this past weekend. All went well, lots of rusted bolts. For some strange reason I forgot to measure before I started the swap. So I'm not sure how much of a lift i have. But I definately need adjustable track bars.....and an allignment. I lowered the trans skid pan a lil over an inch to get rid of vibes (just temporary until I get a MML). This afternoon while getting gas a TJ Rubi pulls into the station. So I pull up next to him to see how my lift measures up. Come to find out he has a 2006 Rubi. We are the exact same heigth. I am sure someone with more experience that I can tell just how much of a lift I have....... face in palm........

JKCliff I just finished installing the JK front & rear springs and shocks in my son's 1999 TJ. I gained 3" front and rear. It rides better. It's firm and doesn't sway as much in turns or rapid lane changes. Total out of pocket for today's 3" lift kit is $90. (note: I sourced used parts from a local 4X4 shop that I work for)

-To make it fit I used TJ BPEs on the front lower mounts, ground the metal sleeves with the bench grinder.

-The front springs fell into place. I got 1" of spring lift and added 2" TeraFlex spacers. I used Daystar extended bumpstops in the front.

-I cut the rear spring, upper coil 1.5" from the end. This allowed it to fit around the upper bumpstop. I then used spacers to lower the rear bumpstop down 1.5 inches. The springs are variable rate and provided 3" of lift.

-Used a set of 2-6" quick discount swaybar endlinks.

I will be going with adjustable trackbars to recenter the axles under the Jp. I will be saving for JKS up/low, Fr/Rr control arms.

Like the poster said above, grind the shock itself. Also on the front shock I didn't bother with trying to push out the bar pin in the old and swapping out the bushing. Picked up $25 Teraflex bar pin eliminators and ground the shock the same as I did to the back. It does move the lower mount up about an inch, so you may have to compensate for that.
