I didnt drive the 355s but they should be in the ballpark of 1744 rpms. The maximum rating for a four wheel drive ram 1500 is 11470 pounds with a quad cab in the tradesman big hornlone star laramie and rebel trims using the 392 axle ratio the 57 liter hemi.

3 92 gears ram 1500. With best in class aerodynamics the body of the 2020 ram 1500 is the model for efficiency through engineering. I favor the 392 because it takes off easier accelerates easier cruises in town easier and stays in 8th gear on the highway more often. One last thing to consideri think the only rear offered with the anti spin are the 392s. I own a 2019 ram 1500 new body hemi etorque 4x4 321 axle i have come to the realization that either sooner or later i will be swapping the gears over to a 392. The 321s turned 1600 rpms at the same speed. Combined with active aerodynamic features the truck gets a 357 drag coefficient.
The elevated hood optimizes air deflection from the wiper area while the sculpted roof design directs air to the rear spoiler. So the 392 is better everywhere from 0 to 80 miles per hour. I understand that the front differential assembly needs to be changed while the rear ring and pinion can be changed. But the 392 will be able to hold 8th far easier on the interstate while still turning less rpm than 7th gear with 321 axle gears would. The 392s turn 1900 rpms at 70 mph. Both were 2wd 1500 crew cabs with the 20 wheels.
