It was lifted before and had less caster than spec. Now it has more, and not by a lot. Drives fine. Is there some quantitative justification for these comments or is this more of a "it's not factory therefore it's bad" approach? (which is ok...just trying to understand.)

I'm all for staying factory, but some folks are running 0 degree caster on 2 inch lifts on stock radius arms with their pinion pointing straight at the output shaft of the transfer case. I think that this is an infinitely more dangerous situation than running a few more degrees of positive caster...

You don't need castor correction with 2" lift... You do when you hit 3"

The extra positive caster will make the steering less responsive moving forward and more likely to come around on you when reversing down a steep slope.

A degree or two less caster than stock doesn't seem to make a difference. Front diff always points at the transfer case, that's how the trucks left the factory.

Ed, perhaps this could help in establishing the proper angles.

im far from "its got to be factory" as you can tell by my truck.... all im saying is that at 2" of lift you really dont need any correction, at three it becomes a good idea... but when you go 6 degrees castor correction at two inches of lift you rotate the diff far enough that you start doing things that the makers of the arms didnt account for.... because they were designed for 5 inches of lift... at that amount of lift with those arms you wont hit any brackets

thank arcadeus. i am specing an additional 1.5" of lift. if i can't find an appropriate 3-3.5" lift spring, then i will have to roll my own using either tf023v or other rear spring.

i just want to say that the amount of lift is irrelevant. with these arms, the fouling occurs way before the bump stops are engaged. so unless the five inch lift prevents the bump stops from being engaged i think this would be an issue for everyone

that said, i have cut off the interfering tab at the axle and am sourcing an offset panhard as well.
