As stated above, it is an active air suspension designed to carry the load on air. The spring is there to locate the axle and maintain alignment. The overload as you discribe it is to protect the system in case of a failure or when the system is deflated with full load

lots of replies on here have never seen the ram air suspension.
its doing what its supposed to do. I have never owned one personally. I have heard some don't like it because the air bags allow the transfer of air from one bag to the other which can allow more sway.
I know Hellwig Products released a sway bar for the factory air suspension. (and I have had to add a sway bar to every Ram 3500 dually I have owned for pickup camper usage)
I think you also have an alternative ride height selection that will lower the truck 1" which might bring that lower spring into play loaded.

I just change my signature, it is a 2020.
Well after a bit of looking I finally found a picture of the 2018 rear air, I have pictures of it when it first came out, but only single spring.
Based on the picture below, the "Overloads" you refer to are most likely in improvement to limit axle wrap on hard acceleration.

Would that be the hard celebration one does after buying the best truck made? A RAM!
BTW, that pic is not current and not representative of the OP's truck.

Have you seen one and understand it? Im almost certain the bags aren't plumbed together, that would be a horrible condition. Each side wouldn't be able to level up separately if that was the case.
Bigger sway bar always helps with a TC.
And OP isn't in the question answering mood, as he's responded to this thread since I asked the same question. Also surmising he isn't in alt load ht and hasn't actually driven the truck with the camper on.
But again, ICBW, as some just aren't good communicators even when asking for assistance.

Neither did you.
It doesn't exist.
The pictured is mixed suspension aka hybrid.
Probably called air suspension to fool uneducated buyers.

Well it does exist, just slightly different way of locating the axle. While you believe that to be a true air suspension it requires a four link with trak bar to locate the rear axle.
Ram uses a single leaf spring to locate the axle. The weight on the rear axle is still carried on the bags.

it does exist as I have one. I have a 5K+ camper on the truck and you can look at picture I posted of the overload spring and they are not being used with 5K+ sitting on truck. I measured the distance from trailer ball to ground before and after loading camper and it measures the same. I cannot say for sure but seems as tho this is a full air suspension rear end.

Are you saying you don't have steel springs?

I don’t think the lower leafs with the bumper is an overload spring. I believe it replaces the link arm of the earlier version to prevent axle wrap.
Looking at the design, with the newer version there is no difference in the frame, no need for a link arm bracket.
