Hey, when you get a chance, would you also post a picture of your pinion angle? I think it's important to see the consistency of this issue.

That's a bad camera angle man.... try getting one from the side at about the same height at the ujoint.
Wonder how your LCAs compare to Superlifts in terms of length...
My LCA's are set to 17.75" I think that is what SL had their new ones set to!

U-Joint angles have been an issue with lift kits since William Shakespeare was still writing plays. :p
Just about EVERYTHING changes with a lift kit, even a 2" one. You need to install the kit, then have a good frame and/or alignment shop check everything. At the very least, it'll need realigned even with a mild lift because things gets changed and moved, including the rear axle which can shift around and the like. They need to also check for crabbing; like those "redneck" lifted Ford trucks of whom you can see one whole side when you're following it. I've seen some so bad, the guy's driving while looking out the wing window. :D
A 4" lift also causes problems with steering gear like control arms and tie rod angles etc. (Especially with solid front axles)
I would imagine every lift kit maker will have parts and advice as to what needs to be included, but IMHO, I think a 4" kit should just automatically include new links, tie rods, sway bar links, and whatever else to make things not be strained to limits after the kit's installed.
^^ yeah we know all of that.
Point is, the Superlift doesn't come with the proper links to correct the pinion angle.
Alignment shops can only adjust what is adjustable. If there's no adjustment, you're SOL until you get some better parts.
Well at least everyone knows what to look for now and if the pinion angle is bad its an easy fix! Just pull out your wallet though

This first photo was taken from as close as I could get to perpendicular and the same height.
The rest are from varying angles FYI..
