If I am trying to remove the air rides in my rear, do I replace shocks or struts on 2005 Cadillac DeVille

Every bump you run over in my Cadillac you can feel in my rear because my air rides are leaking. I dont want to replace them,I want to put the factory parts back in. The only problem is I dont know if I'm replacing the shocks or the struts or both?

Goggle it ,and see what they offer,I'm pretty sure its both ,there together back there ,arnt they?.
I don't believe the rear has struts. I have had to replace the air shocks twice. They are pretty cheap at $85 a pair at Advanced Auto or O'Reillys and have a lifetime warranty, which I plan on using this time around.
