Air ride pressures question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had a similar system on my Burban for awhile. It doesn't take much pressure to make one side higher than the other especially without a sway bar. A couple pounds may be noticeable. Guage calibration can play a part too. On my rear bags the drivers side is at 32 psi but the passenger side is at 28 psi. I'm fairly sure most of the difference is from the guages not bags.

Do you have Larry's 4 valve set up?

Grab a 1 1/4 sway bar from the wrecking yard. 67 to 92 Suburbans. The pickups are the same but only to 89 or so. I paid like $40 for mine.
