Gears for gas 2500

[Rass1313]

Does anyone know where to get aftermarket gears for a 2020 gas 2500?
I currently have a 373 ratio and would like to go 410 or possibly more for better towing. Dealer wants 5800, without a reflash or corrected speedo.
Thanks BR

Waaay too expensive to just change gear ratios. A final drive of 4.10 is really low, so I'm assuming you have some serious weight and not going over 70 mph?

Yeah I was expecting a couple hundred like the old Mopar days.
We upgraded our trailer and now we are close to 14k 5th wheel, 22k gross combined. I'm working to lighten the load as it's over the 21.5k gross combined. The 4.10 is the only difference in getting a 24000 gross from the factory.
We usually aim for 65 mph, and the truck typically stays in 6th. So two more gears available

Pulling heavy, 6th gear is where I would want to be. It's direct drive in the transmission, so almost zero wear. So that's got one of the Dana rear axles? Those are generally pretty tough. Maybe consider a finned diff cover to help cool the oil, Banks makes a very good one.
