I have Bilstein 5100's with Eibach springs.
The springs are made to lift 2.0 inches, a bit more or a bit less depending on the weight of your truck. There were a half dozen or more different OEM spring rates to go along with the powertrain, wheelbase, cab configuration and trim options on the trucks so any one-size-fits-all spring is going to have varied outcomes.
I got more than 2 inches from the Eibach springs on Bilstein 5100's on my RCSB with the lowest setting. How much more than 2 inches? Beats me I've run several different shock/spring/lift combinations on this truck and didn't make any detailed records of the original height. I only know it's more than 2 inches because the height
seems either identical to, or very slightly more than the 2.1" I got from stock springs on Bilsteins at the 2.1" setting.
As far as pros and cons - well unless you're relocating your lower control arms and differential there are some compromises the higher you go over 2 inches. The lack of relative down-travel is what gives trucks that pogo stick ride you've probably seen mentioned a few times because the transition from entirely unsupported (tire in the air, or fully unloaded anyway) to supported has to overcome a lot more preload than a less compressed spring and of course you make that transition a lot more often when you have limited travel to begin with.
Depending how you look at it another con might be the plastic piston shield thing - if you leave that in place and you're lifted more than about 2 inches the bottom of that will be above the top of the strut body and since it barely fits in the first place basically going to get crunched in a day. That may or may not matter to you.
One more thing that may or may not be a pro for you and may not even work out the exact same way with your truck but mine drives, rides and handles like a GT car. I have more going on than just strictly 5100's and Eibach springs and my truck has the 120" wheelbase but it basically feels like a 120% scale Mustang
