Replacing rear lower control arm help!

So I have a 4 inch lift on my tJ with the heim joint front and rear. The rear lowers need to be replaced as they are shot and make horrible noises.


I need help on picking the right ones for me. After hours of research I cannot come up with a good one for me.

Let me start off by saying I do mostly city and highway driving and it is my daily driver. I dont go offroad however I would like for it to perform decent when I do.

I'm on a low budget and would like to spend at most $230-$250 for the rear lowers. Do I go heims, JJ, or JJ on one side and heim on the other?

Ride quality is important to me. Can y'all recommend some lower CA's for me please


Thank you!

Look at the savvy aluminum arms. I run them on my rig with no complaints. The change in on road performance between these arms and the Rubicon express arms was significant.

the savvy's have johnny joints on both ends correct?

ive read that the JJ on both ends are kind of harsh in the city and highway versus rubber and poly bushings. not sure if its true or not.

Pretty sure they do have a JJ on both ends. Have you thought about the metalcloak CA's with they're new duroflex joints? I don't have any personal experience with them yet but a member here (Imped, highly meticulous and a suspension expert to say the least) did a review on them on jeepforum . com I believe. He's a huge believer in the JJ but said he did not have anything bad to say about the duroflex joint. Only thing that hasn't been proven fully is their long term durability. But I'd say they are gonna prove to be a long lasting joint. Just a thought.

JJs are not harsh on the street. My rig rides like a Cadillac with savvy arms and bilstein shocks.

Do you have all arms savvy? Front rear upper lower? My uppers are all stock arms still. Just want to replace the lower rears. I'd love for mine to ride like a Cadillac too haha. I have Bilstein shocks on mine already

It's not; you'll find a few who claim to notice a small amount of added NVH after switching to JJs, but most will say they didn't including myself. I noticed no increase in NVH after switching from stock to JJs, and before that fixed arms with poly bushings to JJs.

The JJ is the way to go in my opinion; the Duroflex from Metalcloak is certainly worth a look, but I don't have any personal experience with them to be comfortable recommending them. Plus you can't really go wrong with the JJ, it's pretty much tried and true at this point.

They're a control arm joint made by Currie Enterprises:

Johnny Joint®

Control arms made by Savvy Offroad, Rokmen, Currie, and some others use this joint.

Beware of copies though, there are some knock-offs out there that the company will just call "flex-joints" or something similar. They look the same, but that is where the similarities end.

I have them in my rear uppers and I am looking forward to replacing all the rest of my arms with them. Nice and flexy like a johnny joint but also a little more vibration dampening for on the road riding.
