Agreed, springs are better. I had loaded a trailer 300 miles from home...longer story shorter, $70 and a few hrs later I had adjustable ride height. On smooth road I can't really complain. Jacked up at 75 Lbs, on the washboard on my gravel road.....pretty bad. Actually the unibody around my hatch is cracking, may well be related. If the mounts are having an issue, I'm not aware of it. Anyway sheez, like 5 years now, I didn't really expect them to last. (the air shocks)(touching the line with a soldering iron, not recommended!)
Anyway I put the filler here, Sometimes for just bumping around here I lower it to 30 Lbs. and run 28 Lbs. in my tires so its not as jarring.

Good to see someone else with them...
The area where the shocks mounts looks very sturdy.
I have the HD springs and by the time the boat and luggage is in it still sits low.Don't like driving in the when it gets dark at 5 with my headlights looking for airplanes so I put Air lifts on. Could not be happier,with no load take out the air still get the original ride.

Yea, again just good springs would be fine but. I buddy has air bags on his chevy that do nothing unless he has his camper on there. Then you get a regular ride with whatever shocks, but you can adjust the firmness of the "overrides".

Installed the air shocks yesterday. It took 45 psi to raise the rear up about 1.5 inches to about stock level. The ride is just as jeep like as before and there is no rear squat under acceleration. I like it very well so far.
Only complaint is the shock absorber isn't as controlling as I like. Going with bilstein hd for the front which have always done me well and control even the slightest bumps. I think if the rear shocks were more vertical their action would be sufficient, but until then we will keep it jeep

Kind if fun when you air it up the first time and see your sagging ars-end rise up, eh?
Kind if funny too, if you go under and touch the line with a soldering iron, it takes a second to figure our why the loud "hiss", and why is my Jeep coming down toward me!

45 seems like alot of pressure, I don't even put that much in to tow the camper. How does it ride on the road? I like mine at 20 for on road and its like riding on a cloud.

I suppose different ones might be different, (probably diameter). IIRC, my info said not to run below 30, (so it stays sealed I would guess), and not to go over 80. Mine are about the same size as a normal shock....

Pi, (3.14), "squared" (times it's self), times "R", ("radius", 1/2, the diameter), will give the area if a circle. That times the Lbs. will give the (presumably upward), pressure of an air shock. (btw, multiply that times the height would give you the area of a cylinder). Handy for tanks or pipes ect.
(2 X pie X R is circumference btw)
The ancient Greeks figured that out for their chariots. Later, in the 20th century, the great thinker/philosopher Groucho Marks made the discovery that Pie R round.
"pi, is approximately equal to 3.14159. It has been represented by the Greek letter "two vertical lines, with a wavy one across the top" since the mid-18th century."
