3.21 vs 3.92: The Last Word

I went from 3.21 to 3.92 and if not for the trailer it will pull, I’d have stayed with 3.21. This truck is horrible on fuel, no matter what I do I can’t get beyond 12 mpg. Lots of get up and go if I need it, but that’s not very often. If I tromped on the 3.21s it felt a little sluggish, 3.92s are much better that way (in a heavier truck - from the cash I have to carry for fuel 😁).
I went from 3.92 to 3.21, haul and tow a good amount and have not noticed a big difference in acceleration, but definitely better mileage.

I’ve had 2 5th gens. Both non etourque v8’s. The first had 3.21’s, the second 3.92’s. I prefer the 3.92, but understand if you want the mpg advantage. Then again, if you want better mileage, then perhaps NOT a truck is what you need. Word

No, I want the best mileage I can get from this truck. Not looking for or expecting prius mileage, just the best this truck has to offer without compromising the trucks ability past my intended use

On your wish list is a level kit, sounds like you don’t actually use your truck. 😏
