FAQ:

Q: Which is better 3.21 or 3.92 Ram?

A: I have 3.92 in my 2019 and had 3.21 in my 2016 the 3.92 does pull better and I’ve not really seen a mpg hit either. Click to expand… I agree on the mpg difference. Unless you live in a very flat area and drive all highway I feel the 3.92 is the better all around option. As for the $95 option that is all BS.

Q: Which is better 3.21 or 3.92 axle ratio?

A: From the speed 58-70 MPH, 3.92 has higher final drive ratio over 3.21 (8.23 vs 6.74) until it has to shift to 4th gear at 70 MPH.

Q: How much does it cost to change rear gear on Ram 4×2?

A: I changed the rear gear on a 4th gen Ram 4×2. Back then it cost me about $300 for parts (that I purchased and supplied to the shop) and $900 for labor. Took them a full day to install.

Q: Can a dealer swap out the rear diff gears?

A: Yes the dealer of your choice can swap out the rear diff gears, please be seated when you call them and inquire as to the cost. The thought has been kicked around a few times here.
