AIRBAGS FOR CHEVY 3500 PSI setting

[Sidgod]

Hello everyone I have a new to me 2020 3791 Montana and I am driving a 2023 Chevy Slverado 3500 diesel SRW. I have airbag in the rear suspension but I don't know what PSI I should set them at. Any Advice would be great.

Welcome to the forum

Your bags probably have a 100 PSI max, so definitely not that much. I set mine so that when I hit bumps in the road my trailer doesn’t bounce on/off the overloads. I would put just enough to keep it level.

I run around 20 psi empty and 50 to 70 psi when loaded with fifth wheel.. I often lower down to 60 psi if towing on the interstate and it not a bouncy section of road.. been running that way since 2007

As the others stated, 50 - 70 PSI, the idea is to keep the truck level, not jarring the load and to avoid having your headlights searching for owls!
DO NOT RUN THEM EMPTY when light, maintain a minimum of 5 - 8 PSI to avoid damage to the air bags.

Air bag settings are a "vehichle, load, road condition and suspension " dependent rate. Trial and error is the best method in my experience. The first set I installed a few decades ago I went through that process and it quickly occurred to me that their must be an easier way to do this.

I installed an on board compressor with under the dash controls and ressure gage. With the on board air I can alter the bags psi as Road conditions change. With our truck & trailer I've found that different pressures will alert the ride and handling. JMHO, YMMV

I agree with all that is said about it depending on your rig. And 50-70psi seems about right.

We carry a battery powered air compressor gun from Ryobi. It works great to add air when needed to the airbags. Easy to store in a compartment or the back seat area of the truck.
