air shocks?

[69nova]

I have a 72 suburban that came from the factory with air shocks (called superlift rear shocks) that I replaced with so called OEM type from advance auto. My burb is lowered and they will raise the rear about 1 1/2" for when I have a full load. I have a 72 swb pickup that I am going to add them to it for the same reason. They work great and if chevy put them on from factory, then you should be OK now. I have picts of SPID label for proof. As a side note, I separated the lines so that each side has its own valve to prevent body roll (air will shift from one side to the other when cornering if they are not separate).
