Looks like I'm finally getting the wheels rolling on a rear axle swap (no pun intended). I'm wanting to do some adjustable upper control arms when doing this, possibly upper and lower. Anyone want to pitch in on where I should look? What brands to avoid?

I love my double adjustable arms by MC. They are so much easier to adjust then single adjustable. If your looking for something cheaper I have heard mixed reviews on Core 4x4 (ebay). All I can say is if you going to wheel it hard then buy once and buy right. MC or Currie you can't go wrong.
 
Most will advise getting the Crown control arm replacements with bushings if you are keeping things stock.
I have 4" of lift and with swapping an axle looking for something adjustable.

So you say double adjustable is worth it? I found a set of uppers and lowers for the rear from Trail Logic for under $350. Never heard had heard of them before, but everything looks nice and same tubing as all the big names that are commonly used on here. I might take the gamble on the small business?

In my mind the double adjustability is worth the upgrade. I'm not sure about heim joints in control arms since I've never used them. If I were you I'd research them prior to ordering.

What axle are you swapping in?
 
Correct me if I'm wrong, but control arm set-up should only be needed once, when installing them. Seems like double adjustable, while nice and offer an easier set up, are not a great value for a one time adjustment.

You are very correct. Once they are set up they are hardly ever changed.

Its more a cost vs benefit. To be honest I don't know how much time you would save with the double adjustable. But some people feel their time is very valuable.
 
As much as I am not a fan of rough country (or many others here), my RC control arms have been just fine so far. If you aren’t going to always be wheeling, I think you’d be just fine with the cheap ones from RC.
Not trying to bash RC, just giving my first hand account of them. There are much better options, but it depends what you’re willing to spend.

For a relatively small premium per arm I would gladly get double adjustable. Some people may get the arms adjusted quickly but people such as @tomtaylz @bobthetj03 and myself have had to make so many small adjustments (.5 degrees) to get vibs mitigated that its worth the extra cost. With double adjustable arms you can change the angle in about 5 min while with single it could be 20+. Now figure your doing 5 - 8 adjustments with test drives inbetween and it can make a day project much shorter.

On top of that if you're not installing everything at once such as lift and sye you could need to adjust more than once.

Exactly my point.

Both do the same job when set. Its all about the time you spend setting them up.

I've settled on the Ford 8.8 for now. I thought about doing the Dana 60, but dealing with the width issue is too much right now. And I'll be DD my rig a lot. With the various truss systems for the 8.8 I think it will be an easier swap and do just fine for me. Dana 44's cost too much if you can find one. Plus the 8.8 will handle the V8 power a little better.

You're 100% correct. That said if you buy double adjustable you'll never be on your 5th adjustment and say you wish you bought single. :p

Rokmen double adjustable uppers with JJ’s too ($330). Actually, these are the one’s I’ll probably spring for when the time comes.
 
If you want to walk on the wild side a bit and go against the grain, Rancho's arms with their D2 bushings might be an affordable option. Think they have a rebate going too.
 
I have the core arms that they custom built to install Synergy DDB's in. I wish I could have gone double adjustable for the uppers but I could not justify the cost. I was able to pull the control arms in about 5 minutes and make adjustments when I was playing with the pinion angle last week. I may still have to play with the angle some more, but I need to swap tires first to fix some other issues.
 
Well to really rock the boat, I went with Trail Logic Industries. Kind of a new company, but all their tubing was the same dimensions (1.5" x .250 Wall DOM Steel Tubing) as the major manufactures I was looking at. For uppers and lowers shipped it was under $350. Plus I got a little price break for being a first responder (the founder and owner is a Firefighter too). Really going out on a limb here by going with the new kids on the block, but we'll see how it turns out. Granted, their only single adjustable, but when I got a full set of uppers and lowers for less than the cost of double adjustable uppers alone from the other guys it was hard to turn down. We'll see I guess. I ordered them late Saturday night and already got a shipping notification before lunch today. Fingers crossed I don't have to come back with my tail tucked between my legs to you guys, ha ha.
 
Ideally, as others have already said, once you get things squared up and proper geometry you won't have to fiddle with them in a while.
