I have had a 2019 Classic with 3:55 gears, and traded it in for a 21’ Classic with the 3:92 gears now, and I’ve only run the stock 20” wheels with factory size tires. The 19’ was a 6 speed column shifter, the 21’ is a dial shifter 8 speed trans. I don’t notice that much difference over all with normal driving, but when I really punch it from a stop the 3:92 seem to get up and go a little quicker.
The trade off is I would prefer the 3:55 for highway driving, in that truck I was probably around 1500rpm cruising between 100km - 110km/hr. With the 3:92 at those speeds I’m at around 1900rpm - 2000rpm which isn’t that bad in a truck with factory exhaust, except I put a Flowmaster 50HD muffler on the truck and you notice a huge difference with noise at the higher rpm cruising. I avoid 98km/hr - 108km/hr because of this added noise, and stick to either under 95km/hr or closer to 115km/hr+ to keep the drone and noise down. Or I have to limit the gearing to 7th to keep the rpm up over the annoying 1900rpm zone.
I guess with the larger wheels/tires that will make a difference and affect everything, but if I could choose again I would probably just go with the 3:55’s personally.
