Can I run the 5100 Bilstein on the rear of my truck with the stock airbags? The part number is 313146 (I believe this replaces the old part number 187174). They state it will work for a truck with 0-2" of lift, but I saw a note on one site that stated it required a rear spring conversion. Collapsed length is 14.91" and the extended length is 23.5". Has anyone run these on their stock truck?

well, that was my first mod. It works. But I also did the airbag trick at the same time.

I plan on tricking the bags just slightly. Maybe 1/2”-1”. I wonder what the limitation is? Will the longer shocks allow the bags to over-extend?
I don't think shocks are intended to be a limiting factor on suspension. You would have more of an issue if the airbags were over compressing the shocks. I think you should be fine with stock airbags.
Its more of if the shocks are longer you need to make sure that your bump stops are going to limit travel before the shock bottoms out. A longer shock is longer at its maximum compression as well. If you're not lifting just get the regular length
I happen to have a set of Bilstein 5160s (25-227611) sitting in my garage that I'd be happy to trade for a case of Yuengling lol. Same extended/compressed length and valving as the 5100, just with the remote reservoir. All you'd need are some clamps to attach the reservoir to the body piggyback style. I think they have about 25k miles on then but work perfectly fine and the bushings are all in good shape.
Here is stock everyrhing vs coils w/5160:
Not a whole lot of difference in flex/travel between the two pics if you look at the wheel relative to the bottom of the body. Just a lot less bouncy of a ride. I'd guess that the extended length is pretty similar to the stock shocks. Compressed length will be limited by the bump stops.

Good call. But I don't see what a difference that makes if you are lifted or not. I would imagine that most people do not add longer bumpstops when the convert to springs in the back, or add a lift. Once the shocks get here I will measure the compressed lengths of the stock shocks and the 5100 shocks to see how they measure up and I will report back.
