Does it improve the unloaded ride quality at all? I drove a 2026 Ram 2500 Cummins yesterday with the rear air suspension and 20" wheels, and it seemed to ride smoother than the ones I've driven with the 18" wheels and standard coil springs, but maybe it was just my imagination!
 
I think my 2022 with the air suspension and stock 20's rides a bit smoother then my brothers 2019 with springs and 18's.
I'll get a bit better idea after I put my snow tires on in a month or so as then she'll be an air suspension on 18's.
 
The air suspension is much smoother.

Despite popular belief, 20’s don’t ride worse than 18’s when the tire pressure is appropriate for the load. I ran both stock sizes of 18’s and 20’s on my ‘22 and alternated thru out the seasons. The 20’s were my preferred wheel for everything exceptional road hunting where I needed a bit more sidewall. The ride and handling of the 20’s was better.
 
My 3500 with air rides better than any of my old 2500's did, though to be fair, those were all leaf springs.
 
I wish the 2500's had the same flexibility as the 1500's with the 4 corner air.
 
I think my 2500 with air suspension rides great for an HD truck. It also handles my 7500# car hauler without issue.
 
So does the rear air suspension replace the coil springs entirely, or does it supplement them?
 
Ok so from the consensus here it wasn't just my imagination - the air suspension really is a nicer ride than the standard springs. But how are they for longevity? Seems like something that would be prone to failure after a few years.

I am aware of that, however I do believe that more owners are satisfied with it then not.
I had no issues with mine in 60,000+ miles. From the issues that I had read about on it, I knew that my first move if it acted up.
I would have added a desiccant filter on the inlet and recharged the system with nitrogen.

Unlike the HD, I understood the 1500 version to be a closed loop system.

Yes, closed loop N2 filled until it needed more then it would use ambient air to make up volume.
 
I love the air ride on my 2500 enough to the point where I wouldn’t buy another ram without it. She rides as good or better than my old half ton.

Can’t speak to super long term reliability, but I’m at 70k miles without an issue, and wouldn’t have any issues with replacing parts to keep it running. It’s that much more comfortable.

Replaces the coil springs on the rear of the 2500 trucks.

However, on the air ride 3500 trucks the bags supplement the rear leaf springs (the air ride 3500 have different leaf spring packs than the non air ride [leaf spring] 3500s).
 
I ended up buying a 2500 Limited with the air....but I couldn't say there was a noticeable difference in a short test drive.
