I have a 2022 5500 6.7 with 4.44 gears. Is it possible to swap to 4:10s?

Short answer, absolutely.
QQ: why?

Curious.

My payload is a truck camper. My total payload is maybe 6,000 lbs. I pull a cargo trailer, total weight under 4,000 lbs. I don’t need the the low end that I’m getting with the 4:44’s. It’s all about fuel consumption, not happy with the 8.5mpg I’m getting.
 
Im not sure if they are making gears for the 19+ yet unfortunately

I would love to know how much my fuel mileage would increase with 4:10s. Even a few extra miles per gallon would be worth it in the long run.

It could net you a couple MPG you would be best checking out a gear calculator app it will give you an idea on RPM change and if your RPM is over 2000 cruising you will be hard on fuel so if on the app it shows 4.10s getting it below 2k rpm at cruising speed that would be a good little jump to your fuel millage as cummins trucks have always seemed to get thirsty once you go over2k rpm

Thanks, that’s good info!
 
Not fully apples to apples, but I know a guy who went from a 2018 4500 with 4.10’s to a 2022 5500 with 4.44’s and gets better bobtail mileage with the 4.44’s.

Unless you travel a ton of miles, or get a huge increase in mileage, the gearing cost would likely not ever pay for itself.

Yep, that’s what I’m trying to figure out. Will need to investigate the gear calculation app.
 
It looks like maybe Ram went from Spicer to AAM, but there are gearsets available for the banjo rear axle in the 4500/5500.

The 19+ pickup axles changed to a new AAM 12" but did the banjo rear on the CC trucks change? I would kinda doubt it.

I had not checked i do know they added CAD to the front axle so that makes me thing the front changed but i dont know about the rear if the gear sets have not changed thats great but i do not know for sure
 
Since the 4500 and 5500 use the same axles and the 4500 can get 4.10’s with a Cummins finding 4.10’s for a 5500 should be easy enough from a dealer.
