You can check out these. Very similar to the Camburg ball joint UCAs.

How do these fit up? Any issues with hardware? Replacing sleeves/bushings?

EDIT -- I see the recommended bushing/sleeve replacement in the link.

NEW Question -- Do these arms have the caster (usually 2 deg) built in?

The fitment was very good IMO. I had no issues, the sleeves and poly bushings fit well.
I'm not sure exactly how much added caster they give you. You could email the seller and possibly find out.
It's crazy how similar they are to the camberg UCAs.
The link in my signature is my build thread with more info.

caster angle

I got my alignment done and the tech says the lower cam bolts are seized.
I get 1.8 left front and .4 right front. Any idea how to fix?

get new cambolts and most likely lower control arms. youre way low for caster, i cant even imagine how that drives.

Replace cams and sleeves and bushings. Typically more cost efficient to replace the entire arm if you are paying a shop to do it. Bonus would be that you also get new lower balljoints (or just replace the arms yourself in a couple hours)

You could also just replace the arms yourself, under $300 for a set off RockAUto or other places. (+another alignment)

if you're not gonna wheel it hard and want the most adjustment possible go with the SPC light racing UCAs. if youre planning to wheel it with any regularity and difficulty the go with either the camburg balljoint arms or any reputable builders of uniball arms (allpro, total chaos, camburg, rockman, icon) or you could try the Ebay uniballs that many of us are running, they do require you to replace the bushing sleeve to get proper fitment. however its pretty easy to do and only cost ~50 bucks to get the new ones from anyone pretty much

I was wondering the same thing. It almost looks like they ran the alignment #'s off a Taco vs. a T4R. The last time I had an alignment done my 2004 (4th gen) spec was 2.5-4. I'm at .5 right now and I'm getting ready to purchase Cambutg BJ UCA's which will add 2.5 degrees of correction hopefully getting mine to 3. When I had my Daystar 2 1/2 1 1/2 I was able to get castor at 2.5 which was fine. FWIW

Thanks for your answer. Also, what if I just get new uca's and just leave those lca as-is?

Starting with the UCA's would make sense, especially if your LCA cams aren't frozen and your LCA bushings are in good condition.

Looks like you got 3"-3.5" of lift? Aftermarket UCA should fix that castor and tighten up the steering nicely.

Also, I looked at your lift pictures, looks to me almost to the point where you might want to consider a diff drop if you wheel.

I see. I plan on getting UCA. Either spc or jba.

I set the bilsteins at 1.75 but the result was almost a 5 inch lift! Most likely because stock springs sagged. I measured 33 to fender and now sits 38 all around. Thanks for your reply. Really appreciate it.

5 inches sounds about right.

OME is a 3" lift spring, setting it at 1.75" adds ~2" for a total of ~5"

I know it sounds like a pain, but I would set the Bilstiens @ 0 if using OME 885 springs. At 5", I would be worried about your CV joints. Setting bilstiens @ 0" would help your caster, extend life of your cv joints. Do that before throwing new parts at it.
