So I wanna build some long arms for my tj. I have about 4 inches of lift and some 35s. I have a bunch of free metal and am in school right now to be a welded so that's not a problem.
My questions are would sold bar work or is that to much? Where do I get the joints? I heard something about johnny joint and I think there made by currie
Thanks for the help
Johnny joints (correct, made by Currie) or Heim Joints are what you will need. All of the fab material places resell them. You will need DOM for the links. Some folks with deep pockets go aluminum. Also, I recommend using the calculators:
Free is free, but you're still going to spend a good chunk of change to build your own long arms. The correct joints, either heim or Johnny, are expensive. I spent 60 dollars on one, when i decided i wanted some lateral motion in my ladder bar.
When building my arms the calc was really no help, don't over think it, just build some adjust ability in the upper frame mounts
Make your arms as flat as reasonably possible
Make your arms as long as reasonably possible
Vert separation at axle should be about 25% of your tire height
Frame separation should be about 80% of your axle but build vertical adjustment into the mounts incase your suspension jacks or squats too much
Triangulation of either uppers or lowers should be greater than 40° to keep the axle nice and controlled
I like my uppers being a little longer than my lowers to help the pinion track nicely
Others may say different but this is what I've seen to work. Every Jeep is different

I think he was saying LONG ARM not 4-link. Long arm is simple- Just make sure and lock/brace and tack the axle into place before you remove the arms to start building. all you need to keep the axle from moving is 4 pieces of angle or square tube- tacked to the axle and the frame to keep it from moving.
