Can those zone or JBA's be used with Bilsteins set to 2.8 or do you really need a 4 to 6 inch lift for them?
No problem. Lots of us are running zones with bils @ 2.8
Any of the name brand uppers should work just fine with bils at any setting.

This is my personal opinion which differs from the opinion from others which is ok. We don't have to agree to everything.

I'll run an aftermarket UCA with anything that liftted my front 2-3" personal choice after having my fair share of IFS vehicles in the past. I won't get into the argument of why people say is needed or not needed with a small lift. I see it just as another IFS application with factory mid lower control arms and the UCA's should have a certain range of motion that allows the BJ to do the work whether the truck is sitting level on the street or drooping a leg down in full or stuffing that same leg in full and that is at stock height, lifted or lowered. Asides from that, typically as you lift you tend to lose caster adjustment and camber adjustment . You can use the offset built into aftermarket UCA's to move the upper pivot forward which restores caster after lift and creates more space to run bigger tires in that same spot which you could use to your advantage, plus you get a truck that tracks better after lift and you can ask your shop for more aggressive camber alignment settings as well, another plus most aftermarket UCA's are a lot beefier than stock and can offer different BJ styles that can suite different driving conditions. Not everybody might be as picky with their alignment or the the way the truck drives, not everybody is into offroading and/or why alignment helps during certain conditions. And lets be honest most simply want the lifted look at the most economical possible way so aftermarket UCA's are typically the first thing you will have in your mind as a saving if you didn't have to buy them to attain a certain height.

The tricky part with the 4-6" lifts is that they include an aftermarket hub knuckle that differs from the stocker in the sense that is meant to keep the factory UCA in alignment with the hub so you can run your factory UCA's and keep the same factory angles after lift. If you add an UCA with offset to that, it will be the equivalent as to doing the same to a truck that is running at factory height. The offset in the UCA will actually hinder or overcorrect the movement of the BJ creating a problem you didn't have before. So you'll have to create the condition in those lifts where it'll be advantegous to you to use an offset in the UCA. I don't have a bracket lift but i see people stacking spacers to go for example from 6" to 8" lift. I'd think that this is one of those instances where you could use an offset UCA to your advantage if the 6" lift knuckle was designed to mimic what the factory one did at stock height and now you're adding +2" lift.. Hopes it makes sense.

To summarize yes it's ok to run Zone or JBA or any other offset type UCA at 2.8" lift with the Billies and there are advantages to it. Some people choose not to and they'll run stockers and they'll see no problems either. So who's right ? Right is in the eye of the beholder and what you do with the truck and how right applies to you :)

Have fun.

I think 2wd 4th gen RAM's can also use 4x4 4th gen RAM front UCA's ? if so i don't know why you can't find them. you have a lot of options when it comes to control arms for these trucks front and/or rear.
