Anyone ever add a rear air suspension kit?

I'm considering buying this to lift my sagging rear end (lol). My right wheels are rubbing on the wheel arches which have in turn caused some minor damage on the wheel arch, which will have to be remedied by a body shop. I can see little scrape marks in the tires too.

According to the video, you just remove the wheel, shove the bag in the spring, install the lines, and add air. I assume you add air from any compressed air source, like a gas station's tire inflator, right?

Some were installed to my very first car (before I bought it)
I never really went looking for the set-up to find out how it worked.
All I knew is that there were 2 schrader valves (standard tire valves) located in the trunk (one for each side), and I could fill them at a gas station.
I just left them in place permanently, and never had any issues with the system.
It was good for towing..... I could pump up the rear to level out the car.

Oops, wrong video. I meant to post this one:

They work great, frankly. Just make sure to get a quality set, and install them properly. A 4x4 shop should be pretty familiar with these. The coil ones are impossible to screw up, you literally just slip them in and inflate.

Just be aware that air springs, like any other springs, will increase the spring rate. I have some on my Titan to help level loads, but I keep them at the minimum 10 psi when unloaded and it does ride differently. At 20 psi unloaded, its damn harsh. In your case, it may be somewhat more of a wash since you are seeking to make up for a sagging spring, but it may not have a linear response. Also, like tires, overtime, expect a small amount of leakage, so you will need to pump it up every so often. My personal thoughts, are that unless you are using them to actually deal with an additional load, then they can be useful, but if you are just dealing with a sagging spring, replace the springs and call it a day.

I have similar ones on the rear of my D21 and I like them very much.
