Hi All

Working on the rear air bags and I would like to know the max
amount of air the rear bags will hold without giving me a facial. :-)

Long live the GMC NET

I have the single cone airbag system and I raise it up so the grease port on the axle is exactly 13" and that produces about 85-90 psi in the bag.

Max pressure for full raise is around 120 PSI.

I've had mine as high as 120 lbs leveling the coach in a campsite, but I'm not
comfortable at that pressure so now I rough level with boards under the tires
and then use the air system for the final adjustment. I try not to go over
100-110 lbs now.

I'll be interested in seeing what others have to say.

I believe the rated working pressure is 130 psi, but a good bag will sustain substantially more than that as a safety measure.
