Lower and upper control arm brackets

I took my jeep off roading and I bent my upper and lower control arm brackets. I need links to durable and affordable brackets (upper and lower)
Also thinking about getting better control arms if there's some cheap ones. I need weld on brackets.

Thank you!

Front or rear brackets on the axle? IRO has some brackets, as does many others. Look for a truss if you want sturdier upper control arm brackets. Google "Jeep D30 axle bracket" and you're gonna find a lot of stuff.

A common way to improve front passenger side UCA bracket is to fully box it and then add some gusseting. Lowers are built weak from the factory to collapse on higher energy impacts (just like OEM control arms), but due to that they can't handle heavier wheeling much at all. Welding a plate between the sides of the bracket (also called mini skids) help on the front LCA brackets, but it doesn't make them bullet proof.


Rears aren't that weak, but can be bent if they get a good hit. Look for a truss for the uppers, there are some companies making rear LCA brackets as well. Most rear LCA brackets are high- clearance mounts which actually mess up your 4-link geometry unless upper mounts are re-located as well.
If you bent the frameside brackets, tough luck.


As for aftermarket LCAs and UCAs, search if you want the cheap crap. About a gazillion different manufacturers for those. Cheaper ones use factory-style rubber bushings (crap for wheeling), polyurethane bushings (crap for wheeling and increase NVH on the road), or a combination of flex joints (Johnny joints being among the very best on ball- type flex joints) and rubber or PU bushings. There's also Metalcloak duroflex CAs, of which I've been hearing only positive feedback.



Btw., if you can weld, you can fab your own brackets from 1/4" steel plate and box steel - with an angle grinder and a drill.

Use the IRO ones for the lowers.

Build your own for the upper, or go hack one off from a junkyard XJ/ZJ/TJ/MJ axle, burn it on your axle, then fully box & gusset it. The one you linked for the D44/D60 won't work as is, because all Jeep D30s with 4-link front suspension have the front UCA bushing pressed in the axle bracket, not the control arm.

Also note, the IRO brackets you linked don't have provisions for cam bolts. If you are running non adjustable arms you will need to do something to be able to adjust castor.

Artec has very nice brackets: http://www.artecindustries.com/Dana-...air_p_372.html

They also make an excellent truss for the d30: http://www.artecindustries.com/Front...-ZJ_p_334.html

If you're going to be doing that much work on a d30 it would be a good time to think about an HP30.

HP30 is the high pinion dana 30 that was used in the XJ cherokee.

The ring and pinion are slightly stronger, and the driveshaft is above the centerline of the axle.

You may have some interference issues if running HP D30 with stock height, I had driveshaft touch the tranny lines on big bumps on mine.

He's got a 2" BB which should be plenty of clearance.

quick question....did ALL ZJ LP 30's come with the adjustable cam slot on the axle side? my new to me 1993 base model does not have the cam slots, just the hole like an XJ HP 30, no it's not a HP 30, I've looked at it a few times to confirm.

It could be a first gen thing. Or it could be a early 93 thing. I haven't spent that much time on the first gen ZJ's. I know that there is some difference in the front LCA's, I've had the wrong LCA's shipped to me a couple of times.

Does it have the shims like the XJ?

The difference in LCA's is:
- Axle side bushing: ZJ is slotted, center sleeve is same width, interchangeable with XJ-style solid bushing
- Frame side bushing: ZJ is solid, center sleeve is wider than XJ, can fit a XJ bushing if using XJ adjustment bracket as a spacer.

You need to match gears, you have 3.73 right now. Some XJ's with the 4.0, auto, and tow package have 3.73s. You don't want a vacuum disconnect axle. Most XJ's don't have abs so you will need to swap in your axle shafts (with tone rings) and maybe even knuckles for the abs sensor if you want to keep abs.

Also, don't get a 2000 and up as those were LP.

If you are welding on brackets anyway the rest shouldn't matter. There is a slight difference in CA mount positions supposedly.
