I installed a set of airlift airbags on my 03 2500 HD Silverado. Wondering what a good air pressure is to run on them with a 8500 lb Cougar 5th wheel. I put #45 unloaded but seems like it needs more.

I used to keep 50-55 in mine, loaded with fifth-wheel and 20 when not loaded.

If you are using the air bags as designed to level, it is simple as taking some before and after rear bumper measurements.

They are designed to level the truck when hitched, nothing more. The amount of air in them will vary with every setup.

What super dave said, I installed them to level my F250 first with the 5ver, then later with the Lance Truck camper, 50 lbs would level my 5ver and when empty i ran 5-10 lbs. 65 lbs with the Lance.

I had Firestone air bags and were very happy with them, they were still working when I traded my 99 F250

I guess some people have reported having problems pinching them if running empty. I've run mine for 12 years empty when not hauling and never had a problem. With a 1 ton dually my empty ride is harsh enough that even 5 lbs. adds unwanted bounce.
