Yes, very easy. Takes about 5 minutes.
Disconnect air line, remove two top retaining clips, unseat bag at top, twist 90*, and remove. The hardest part is not losing the retaining clips.
I have 4 of these bags in good shape from removing them for conversions. I am toying with the idea of using them in a trailer suspension. The jury is still out though.
One thing you can (and should) do if you have the airbags is to frequently and liberally spray them down with WD40. It will keep the rubber soft and help prevent cracking and abrasive wear.
