Rear Control Arm Upgrade, 4 link? Other options?

[mulletator]

Hi Guys, I have an '06 Liberty CRD. My rear upper and lower control arms are shot and I want to replace them with something stronger. I've seen a bolt-on 4-link system from JBA that would be awesome but they no longer carry it.

the JBA system is seen here: https://www.jeepkj.com/threads/jba-tri-angulated-bolt-on-4-link-and-jba-1930s-exhaust-headers.74021/

What other options are out there? I don't want to replace my parts with the OEM stuff because it will surely wear out again soon.

I have two of the JBA uppers on my 03 and 04 , they work great
the one on the 04 is the preproduction test model we used to see how it would work before it was released and still doing great
I am currently trying to find time to install a set of CORE 4X4 lower adjustable control arms on the 03
they are for a WK Grand but will work, can set them at the right ( well stock ) length etc

Someone makes a bracket to mount a WK rear upper ( very expensive ) but may be a way to go
info on here somewhere

Thanks tommudd, I'll check that out. I should mention that I have a 4" JBA lift on my KJ. I have the JBA rear UCA extension plate but I want to go with something stronger overall.

I'll dig around for the info on using WK parts on the Liberty, I'm open to options. I want my Jeep to be strong. I'd 100% buy the JBA kit but they no longer have it available.

The upper arm is from iron rock offroad and the bracket is mage by "wwdeisel" i think he's more prevalent on lost jeeps, but he's here too. I looked into a while back, but decided I've got a few more miles left on mine.

 

[tommudd]

Yes I know, was sad when Marlin downsized his business
Wish I would of moved over and taken over when he asked , since then we'd still have KJ/KK parts

I have the JBA coilover kits on the 03 and 04 as well

Awesome guys, thanks. I found the WWdiesl stuff here: http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?f=59&t=89576.

That looks great, it should be way stronger than the stock stuff. Do you have contact info for WWdiesel? I'm not on LostJeeps.

tommudd, can you tell me which CORE 4X4 lower adjustable control arms will fit the KJ? Will any adjustable WK fit on the KJ with the right adjustment?

I'm just looking on the Iron Rock site, they don't seem to have a rear control arm for the KJ. Does the WK fit?

Like mentioned before the UCA is for a WK, that will work with the bracket wwdiesel sells
which lower control arm???? FOR A WK Grand yes they will go down to the approx length of 17 inches to put the wheel in the right place like stock
there is NOTHING advertised that it fits a KJ anywhere

Thanks tommudd, you have been very helpful with this information which is difficult to find.

I understand that nothing is advertised for the KJ rear UCA and rear LCA. It sounds like the WK rear UCA will fit with the correct bracket. I didn't realize the WK and KJ had the same mount points on the front part of the UCA.

I just want to confirm before I order the lower control arms. I'm sorry to keep asking but it would be a huge pain in the ass to order the wrong parts and find that they don't fit.

You are saying a WK Grand LCA will fit the 2006 KJ if the length is about 17". Is that correct?

Tried another company that sells some LCAs but after 20-25 emails, waiting way over a month I went with CORE4X4

will fit 02-07, no changes over those years as far as suspension

as far as difficult to find, well been combing through many companies etc over the last 16 years owning a KJ to find things, so have found a few tricks along the way. Plus working closely with Marlin ( owner JBA ) has helped

Thanks a ton, tommudd, I'll order up a set right away. I appreciate you passing on the information that you have painstakingly gathered. The KJ seems to be the black sheep of the Jeep family when it comes to aftermarket modifications.

It's a shame that Marlin at JBA has stopped carrying KJ stuff. When I got the lift kit from them a couple of years ago they had all kinds of cool KJ stuff. I wish I ordered more of it at the time.

I just need to sort out the bracket for the IRO UCA. I can't seem to find contact info for Mr. wwdeisel. I might ask a local fabricator to give it a shot, the can probably model it off of the JBA extension that I already have. If wwdeisel has some already made and powder coated though, that would be easier.

 

[tommudd]

You'll need something way different than the JBA extension you have now

Yeah I know, I mean they can get the bolt pattern off of that plate. I'll try to get ahold of wwdeisel though. I've seen posts showing off his stuff. It seems like he already has them powdercoated and everything (http://www.lostjeeps.com/forum/phpB...&t=90135&sid=5259ff8fe5fb38b89af3b02d71439ef9).

Only thing is I'm not a member of Lost Jeeps yet. I tried to sign up but I didn't get the email confirmation. If anyone has his email address or something please share it with me.

Go up to top of page and put WWDeisel in user ID search. Doesn't look like he's been on this site since 2016, but you might could get an email to him. If that doesn't work, I'm a member on lost (if I can remember my login) and ask him to revisit here and find you.

Hi wwdiesel, good stuff. I'd like to order one of your mounts. I don't know how to do PMs on here either.

Send me an email at [email protected] please and we can figure out the details.

If you tap a persons icon there is an option to message them. I believe that is how it's done.
