Question What pressure to set my air bags

I installed new airbags in the front springs of my 98' Georgie Boy Swinger and I was wondering what pressure I should put them up to?

What's the minimum and maximum pressure for the bags? Start in mid range and see what the ride is. Go up or down from there. Only you can determine what works best for you.

There should be a kit available to run the extension hoses to a common mounting place for easy access.

Locate the the rubber bump stops on the front suspension. Measure the space between the bump stop and the landing pad. Set the air pressure so the space is 1 3/4". Done!

This sets the correct ride height for your P30/32 chassis.

On my P30 I added a little extra to the right side to compensate for a slight lean and road crown.

Guessing that it has the Chevrolet P30/P32 chassis, there is quite a lot of latitude in the air bag psi for personal preference, i.e. softer ride vs firmer handling on curves. There are also baseline values depending on the front axle GAWR.



Section 3.8 of the P32 chassis service manual covers setting for the air suspension. See it at https://www.gmcmi.com/wp-content/upl...sis-Manual.pdf

On my 1998 pace arrow I used 24 psi. On most of the coaches that I installed airbags the owners preferred the mid twenties.
