2021 F350 4x4 Caster
Recently added a 1.5” spacer up front, installed 2 degree caster shims, along with some 35x12.50R18 Falkens, getting a slight pull to the right now, alignment is good, I’ve read it may need more caster potentially? Axle is within a 1/16” of being even even per side, any thoughts? Also tried swapping the fronts and still getting the pull

Typically you need a little more caster on the passenger side to account for road crown. This is called cross caster. For example, you might see 3 degrees driver side and 3.4 degrees passenger, that will usually drive reasonably straight on a normal road. If you had the same caster or cross caster in the wrong direction, it'll pull right.
What's your actual alignment print out look like?
Sometimes certain tires will pull too. I had some Generals that pulled right. I adjusted my cross caster. Swapped to Cooper's when the Generals wore out, truck pulled left, adjusted cross caster back to original and it drove straight.

I did the same thing and mine drives fine. I did install an adjustable track bar, but I don't see how that would affect pulling to one side.
If you installed the tires at the same time I would swap them to the rear or side to side and see if it changes anything. I had a Continental with a slipped belt, and it pulled bad. when I went to have it warrantied, they said no, that's not covered just don't run it on the front.
