Upper control arm Q's

Please forgive my ignorance; my prior lift experience is with solid axles.

I understand why LCAs are necessary for lifts over 3" or so to avoid handling problems.
Conversely, would handling problems also arise if UCAs are installed on a lift of 2" or less?
I see they are adjustable... is that for the amount of lift, or alignments (or effectively both at once)?

Thanks for any help. All I could find searching was info about using them on larger lifts, but if you want to flame my search skills anyway, I have thick skin so bring it on!

Yes, I know that.
I'm wondering the opposite... will you be too far in the opposite direction and have problems if you put the UCAs on a lift that is 2" or less?
Or is it totally pointless to do so?

Thanks PSU.
I haven't decided yet if I'm going to lift, but if I do it will only be 2".
I don't want to change the handling of the truck, but it sounds like I can cross the UCAs off the shopping list.

what is the main advantage of the uniball style over something like LR UCA? do i just not understand the greatness and power of a uniball?

My understanding is that the Uniball allows more down travel than the stock ball joint before it will bind. I am certainly no expert tho.

Dang. Too slow... what he said^^^

Yeah, skip the ucas when lifting only 2"

Check the troubles Nick54 is having getting alignment and rubbing correct.

One fewer variable to mess with.
