Most folks will point you to Savvy double adjustable control arms.

Core 4x4 also makes single adjustable. They used to have Johnny Joints...that might have changed. Single adjustable makes it much more difficult to dial in your alignment.

I'd also suggest the JB conversions super short SYE and contacting Tom Woods for a double carden driveshaft when everything is installed and you've measured from yoke ear face to yoke ear face.

Savvy, Currie, Core 4x4 with Johnny Joints are the preferred control arms around these parts. There are others, but I’ll not open that can of worms. Rough Country is universally despised.

So
 
I would consider the maintainability and durability of the joints the most important part of the decision. The adjustable end of those core arms looks good, but I can't tell if the other end is a clevite bushing or a poly bushing. Clevite is OK, but harder to replace in the future. Polyurethane bushing are just bad.

I don't disagree that double adjustable arms make setting up or changing a suspension easier. They also provide a finer degree of adjustment as most of the ends are 12tpi, a half turn on a singe adjustable end is 1/24th inch.

I chose single adjustable not because of budget, but because once I had it setup I wasn't planning on making additional changes.
 
Buy once, cry once.

I'd go with the Savvy arms as Mac said.

Johnny Joints are more expensive but they're rebuildable and easier to get parts for.

For extra $100 you can get core 4x4 arms in double adjustable.
 
I will say this about adjustable control arms...make sure they're tight. And if you think they're tight...check again. You need a big wrench and a lot of force.

Mine came loose in Moab. So did others...loose control arms lead to bad pinion angles and shock interference and destruction.

I can see by the other picture from underneath your rig that either the arms had already come loose or you need a few tightening tips. How are you tightening the jam nuts on your double adjustable arms?

I noticed that too and fixed it! Older picture!

Am using your tightening procedure!
