Air Bag Pressure

The 5 psi is the UNLOADED pressure as the PSI increases with load. I would run my PacBrake bags at 5psi unloaded but when the 4,500# pin was applied the bag pressure would hit about 30psi.

With that small a trailer. You don't need more than the 5psi. Minimum the manuf recommends.

Keeping 5-8lbs in them will keep them from getting damaged on large bumps or massive potholes. Plus that way you know if they get a leak when you check the air. You don't need more air than that unless you notice significant rear end squat. 2500lb+ I would imagine.

That is the information I was looking for not if I can drag it around America. Thanks Cummins!! I just wanted to double check

Happy to help!

Rather than the succinct response I was going to post, I'll be serious and say......none, unless there's more to your question than hooking a smallish trailer to a truck with a payload capacity north of 2 tons.

I will be traveling with my cargo trailer and pulling it with a Ram 3500 dually with airbags. The whole set up is no more that 5k in weight. What air pressure would you set your airbags?

Seriously?????
Zero if they have the bump stops in them 5 psi if not!! :S

Edit: I see you have a six speed, I would not even use 1st gear towing that littler!!
