I just bought a 2023 Classic Hemi with 3.92 gears.

Agreed.It's all related to rpm, you can get the same mileage as 3.21's if you have it in lower rpm's, as in drive a little slower on the freeway. The good news is you cant adjust 3.21's to give you the benefit of 3,92's. Can handle larger tires and loads. They are very desirable imo.
Nice, I'm also in Florida. I'm sure there is many posts. Thanks for the reply!Lots of mileage posts on here... I have 22 bighorn, quad cad, 4x4 with 3.92. This was a trip I took just over a year ago, mostly flat FL highway mileage. This was with 89 gas. Around town I get about 16 to 17. I use 93 gas now, I think I get a better percent increase in mileage then the percent increase in cost per gallon.

What width rims are you thinking about?Agreed.
What I'm noticing with the 3.92's is that on the highway I'm not continually shifting in and out of 7th & 8th gears like I did with the 3.21's.
This is a huge bonus for me in terms of driving comfort and reduced wear and tear on my transmission.
I'll gladly sacrifice some fuel for a happier truck. I'm also looking forward to when I put my 35's on soon, too.
On my 19' they were the factory 20" black aluminum rims that are 8" wide.What width rims are you thinking about?
Gotcha, factory rims.On my 19' they were the factory 20" black aluminum rims that are 8" wide.
On my 23' Warlock they are the factory 20" black aluminum rims that are 9" wide.
Good info thanks, yea the wife mentioned 35's. I already have a Chevelle that sucks gas. It's going to be more her truck then mine.You might experience a decrease of 1-2 mpg's when you put the 35's on. Just more rolling resistance. Not against 35's..just sayin. Also depends how/where you drive too. And tire type of course.
Who was it?? Some forum member said they lost 1mpg for every mod they did... lol
