I did the XREAS delete and replaced the airbags with Dobinson rear springs for ~2" lift. I unplugged the shocks and replaced them with the 5100's. Then I disconnected the air lines from the air tank using the caulking cap method. I took it for a drive expecting a trouble light to flash at me and there isn't one. The height level light is on "N" as if nothing has happened. Is this normal?
