Air bag pressure

[upon1]

I’m running a triangulated 4link on the back of my ‘55 with an accuair setup. For some reason I have way more pressure in one air bag than the other to keep truck level. Any ideas? Each side is set up exactly the same and am running the Firestone sleeve type bags.

If you had access to scales you could check your corner weights. The main reason you would have differing pressure would be more weight on one bag, causing a need for increased pressure for the same height. A second reason would be suspension design, having more leverage would mean less pressure needed but if you are sure the suspension is perfectly symmetrical then it is probably be weight.


The last possibility is how you are measuring the pressure, two different gauges of a single dual needle. You could swap the gauges or lines to make sure you have similar readings for each corner.
