Suspension question

[phlfly]

I got truck with already rear air bag/spring were installed bt previous owner. So I took for quick trip for off road, to try truck and to know limits. So what is interested with airbag it would not flex much and keep wheel on ground, check pictures below. Airbag at 10 psi each as I read 5 psi is too bouncing. So my question is good or bad, I have no idea about those things?
Truck at 13 deg angle.

Need a pic of the bags. Not flexed or anything, just need to see type of bag.

While the ground is angled, it looks too flat to flex much. Set just one tire on a rock.

There is, its air lift.

Try a Daystar spring cup. Might have to reroute that vent or brakeline in the bottom of the pic.

Should worlk with those bags. If not there's a company that makes knockoff Firestone bags cheap, that'll most likely bolt right in. Maybe drill the mounting plates, but I doubt it.

Are the air lines coupled or is there a separate supply line to each bag?

 

[phlfly]

yes , it has separate line, so you can adjust each sprig individually.

So Daystar is allow air bag travels with rear diff flex, is it right? As right I have all hard bolted together between frame and rear diff suspension, is it what you meant to say ?

The Daystar cup allows the bottom of the spring to be unbolted. So the axle can droop as much as it did from the factory. Airbags often restrict down travel.

It'll also prevent damage when the truck is on a lift.
