My Express came through with the 3.92s as an added option factory build. With the 8spd trans, 8th gear is overdrive. And I can drive around a lot in Eco mode.
the 392 depending on how one drives has eco mode on quite often and on hills pulling weight it does not hunt for lower gear much at all some times never depending on incline.
I really thought about the 3.92s, but I highly doubt I'll need the extra 3k or more towing capacity it offers.
At worst, I'll just bite the bullet with install costs in the future, as I found a truck on the lot with the options I liked with a good deal on the selling price and the trade in.
Ok just another update I do have the 3.92 gears and you folks were right I did not notice a difference between that and the truck with 3.21. Although I can say according to my dash I’m getting 14.5 miles around town lol.
I feel that with 3.21 gears and the Pedal Commander you’ll get out of it exactly what’s needed.
When I was Loosely considering a 2019, I could not find 392 gears anywhere. test drove the 321 gears, and I refuse to own one of those.
^^^^^ I'm counting on the e-torque being my pedal commander. I also went with the stock gears.
