Difference between air suspension orp/rebel/non-orp

[Beegle19]

So I know in the standard coil sprung trucks the off road package and rebels have a longer front strut and different mounts to achieve the height differences.

How is it achieved by the ones with air ride. I know those trucks don't get off road 2. Is it just a longer strut? Different mount point or do they just come basically one setting higher I.e aero=normal, normal =off road 1 and off road 1= off road 2?

This is something I have slowly been trying to find out. The air ride suspension looks different from a Rebel to a non-orp.
