Sorry to hi-jack the thread, but..
Damm. This is exactly what I want to do. I have a few questions if you would be so kind..no problem.
So I'm understanding this correctly, you just used the synergy 4 link brackets and only utilized the passenger side upper mount, welded on a new axle-side UCA mount and threw on on some 7075 arms? Correct. I also already had an ARTEC truss, so I added the UCA mount on top of that, but I have helped others set this same kit up and its the same drill.
Do you think a 4.5" lift would work(nothing contacting each other) with this setup? I see that you are around 7".
I think it would work, you would have to bumpstop properly, but I see no reason why these brackets couldn't be used at lower lift heights. you may want to use a smaller diameter material for the upper link maybe a 1" shank joint and some 1.25"x.120 chromolly for clearance.
Are the lca bracket mounts pointed straight at the axle end lca mounts? I am wanting to run a self centering joint on at least one end(metalcloak-synergy dual durometer...etc)they are not pointed perfectly straight at the LCA bracket. Synergy designed them for their arms which are bent for tire clearance. with straight arms the JJ has a little bit of the misalignment used. maybe 5*. honestly the currie Johnny Joint is a way better joint than any of those "self centering" joints.
