That's true, but at the same time I'm thinking due to the geometry they're designed to, adding more lift will draw in the bottom of the knuckle and push out the top of the knuckle, pivoting the knuckle about the tie rod (which sets the camber further within spec, assuming the camber is on the edge or slightly out of spec now) which would give more clearance between the tie rod and wheel edge.
Looks like someone needs to do a CAD Drawing of the front end with both UCA's and see how the motion flows.

I just have the 4" SL and JBA UCAs with no spacers or additional lift. Plus, I verified that the Pintlers were the ones for the XK (25mm offset?) and not the JK ones (10mm offset).
That SFA conversion is sounding better and better.

The JK Pintlers would actually be better. Assuming their posted offsets are correct (because their Xk backspace is calculated wrong), the XK version would have 5.75" backspace and the JK version would have 5.15" backspace..... 5.75" is pretty far into the wheel well and would cause more interference with the tie rod.
Have you tried measuring the backspace? If its really 5.3" then they have +14mm offset, not +25.
Is the wheel width measured from the inside of the beads?
Yup
Edit: and the backspace is measured to the outside.
There's a sticky at the top of the wheel/tire forum where I posted a downloaded excel sheet that I made; it converts offset to backspace, And back, and even lets you put in two different wheel specs to compare.
Do you guys think I will have a problem like this if I keep my current setup stock rims with spacers then get the ome front set up minus a coil on the front springs and get RRO UCA?

Probably not.... you have 1.5" spacers right? That should give you a lot of clearance around the tierod. The XK pintlers, if they are 25mm offset are like running stock wheels with 1/4" spacers in terms of the inner wheel edge location.
Are you sure the back spacing for the XK pintlers is 5.75???
