For you Riviera owners. I added part number 60755 Air Lift Air bags to the rear of my 1970 Riviera to restore a little height when fully loaded. The car ride height is correct in the rear but put five people and gear in the car and things get too low for speed bumps. The coil circumference allows the bags to fit but I had to remove the springs and flex them to open a space between the coils to push the bags in. In my case I used my truck receiver hitch w/ 2" ball with a pry bar. Place the top small spring coil around the ball and secure a pry bar at the bottom coil. Imagine the spring upside down on the hitch. To be absolutely safe use a second person, one to flex the spring to one side and one to stuff in the airbag.
I had used Air Lift bags on two of my turbo cars, and had one of the burst on the passenger side. Mind you, I put both bags on that car, with separate feed lines to each bag. On the other car I only installed one bag only on the passenger side to pre-load the suspension. That bag also failed at some time; no Idea when. I went to my storage area to get the other bag and found that it had dry-rotted in the box. NEVER USED! Disclaimer: These were over ten years time from original purchase, but the failure was within five years. So, I guess the moral of this story is: Don't trust Air Lift bags. Yep, mine looked like those in your picture. And they were genuine Air Lift, in the sealed box when I got them.
Airlift is clearly not a long term solution just like tires and shocks. There was clear information about this by Airlift. I in fact had to replace the bag on my GN because of rupture from stretch and dry rot. The instructions also state to never keep the bags inflated over extended periods of time. So, yes I agree with you that care and inspection like everything else on the vehicle must be performed.
I replaced my Air Lift set when I changed the rear coils with OEM replacements about 6 years ago. Never had issues...but when installed, it is necessary to heat-wrap or shield the exhaust pipes which pass very close to the rear coils. If the pipes are not insulated, the heat will pop the bags.
