Rebel and ORP (off-road package) share the same taller springs to achieve 1” height over a normal Ram. If you don’t have ORP or a Rebel, you have “normal” springs.
I don’t know much about either, honestly. You’ll probably find what you’re looking for by searching around tho. That said, rarely will you see two options compared. Usually, once someone puts a lift on, they don’t remove and install another on the same vehicle to receive an actual A to B comparison.
I know most here are just doing spacers along with the stock springs.
I went Bilstein 5100 on all 4 corners, and lifted my front 1.5” on the #4 clip setting to set my truck level. If you’re going 1.5” higher with Icon spring in the rear, you’re going to have to lift the front quite a bit to level, if that’s your goal. To do so, you may want to consider what that’s going to cost, as you’re probably looking at 3-3.5” front lift to achieve it. That may involve upper control arms to correct the ball joint angle, for example, and a stiffer setup than you want.
Here’s my setup
