With the cost of freaking fuel right now I miss the additional 5+ MPG I was getting with 3.21 gears overall. That being said the 3.92's in my current truck are far less sensitive to driving style and towing than the 3.21's. For a daily driver (40K miles/yr) I'd take back my 3.21's in a heartbeat
You know, I must be a real idiot or I must be halfway intelligent, because it's only one of the two here! I have a limited 4x4 Hemi eTorque with ramboxes and pretty much all options ticked being built, but after much much much much debate and back and forth, the *ONE* thing I did not get was the 3.92 gears. I plan to leave it on the stock size tires, I don't plan to offload or tow except for very very very occasionally, and when I do, it will be around 6klbs tops. I do a lot of highway miles where I'm going 75-85mph and just figured the 3.21 sits better at that highway speed. I drove my buddy's 2022 limited and he's got the exact same configuration I've got but with the 3.92 and I barely touch the accelerator and those wheels spin (he's got the anti-slip differential too). Don't need all that. I want torque but not at the cost of traction all the time. So, I figured where I could use the gear difference is in the top end to use MDS more and to take advantage of a slightly lower RPM. Figured if I have the truck 10 years, with 2-3mpg difference between the gear ratios at highway speed and filling up the 33g tank with 115-120 worth of gas once a week, I'll have saved closed to 8 grand in fuel costs.
Didn't go diesel as those things like to have a bit of load on them a bit more regularly, and I just can't give that engine what it needs to stay healthy long term.
