Delayed updates...
Emailed SFR on the length of the links, not much help, just said axle brackets must be closer on axle then stock... maybe true.. but almost 2 inches? I've also noticed few pics of people posting this kit on Facebook, all the JJs are threaded out pretty far. I think they are definitely on the shorter side. Ended up ordering new lowers +2" from WOD, also upped the diameter to 2". I then was able to reuse the lowers as the uppers, just barley, had to push the front axle forward a bit to get caster adjusted, but it all worked out.
New WOD lowers vs SFR lowers
SFR original lowers vs SFR original uppers
Since I moved the axle, pulled the springs to check everything for clearance.
Driving around had the exhaust rattling on the transfer case skid, found they welded up the cross brace backwards, they had the relief cut for exhaust on the opposite side, easy fix with the grinder.
So I mentioned I had a shop regear to 5:38s a while back, well the front gears whined from day 1. I went back and forth with them, multiple trips and "inspections", ultimately they claimed no possible way it was the gears or their work. I ended up having to prove to them it was gears by pulling the axle shafts proving the sound was gone with the gears not turning, they finally agreed, threw a new set in... and now perfect. Of course this was 1 week before KOH so I put had to drive it a bunch in a short amount of time to get some break in.
