I didn't pull it, i've been gone away, just checking in on my phone.
Must have been pretty gruesome.

Anyone have an Opinion on a Radius arm 3-Link design? What's the good vs bad?

Assume you mean a short upper arm attached to the lower link, and not Ford style radius arm bushing?
Good - easy to fit in tight places, cheaper, less joints, easy to design.
Bad - can be a bit squirrely under heavy braking with one upper arm, tends to pull to the side. If you have two upper arms, it binds when flexing, makes the axle tube try to rotate in the diff. trac bar needs to be extra beef, as you only have 3 frame attachement points for the front suspension. All brake force goes thru upper arm joint, leads to rapid wear of low quality joints. Needs high quality hiem, no rubber or urethane. Same for tracbar. Pinion angle changes thru range of compression/droop, unlike 4 link.
I designed and ran front radius arm (single upper arm) on my black ZJ, it worked successfully for years. My major problem was beefing the tracbar. On Scott's similar setup, his big issue was eating upper arm joints, causeing all sorts of handling issues, erratic control while braking, and also destroying aftermarket tracbars.
They both worked pretty good in the woods. The pinion angle change thing didn't bother me at all, I ran limiting straps to control how much it could droop.
Scott has since gone to a 3rd upper arm, and my ZJ is in the grave from unibody rot. I was happy with mine on 33's.

That Dakota Is Awesome! I'd assume they have similar characteristics but this is more of the design i had seen. Where the upper and lower arm are connected. From another Angle you can see the driver side arm. I stole these pictures from Bluetorch Fab.

ya, its the same thing. You can make them look a million different ways, but just focus on the attachment points.

Is there any advantage/Disadvantage to connecting the upper and lower arms together?

The setup I have is a Rough Country Deal, The upper link does attach to the arm but is not gusseted to the arm. I read into it some seems it's a lot stronger to Gusset them together especially if you plan on running it like a 3-link. So I guess I have now answered my own question, Thanks for the help guys. Working on the house doesn't leave much time for reading up on ideas.

3 link is one seperate upper , with a frame and axle attachement point.
whether you gusset the radius arm or not, does not make any difference as to what type of link setup it is. its still a radius arm.
you have to be pretty cafeful picking your terms when talking about this stuff.
Think frame/axle attachment points, not what the links look like.

Yeah I was unsure what to call what to call it (and kind of still am even tho it probably is still just called a Radius arm setup), Where it's a Radius arm on one side but only the lower on the other.

Scrap all that, It's going to keep the Standard Radius arm setup I have, New OME 891's where installed in the back tonight. It sets about 3.5-4" lower now than it was with the OME 864 springs in there I'm a lot happier with where it's sitting now.

ok, back on track. lol.. Got the new rear springs in and the exhaust out..(the part that got me).. hopefully, tomorrow I'll be mounting the drivers side arm.. Then pulling the axle for the rebuild portion..
the new ride height is more at where I originally wanted it. it could still drop a bit, but is good for now. also upgrade to progressive rate coils..
