Gears

[AE_Ram19]

Does anyone know if the front gears can be changed in the 19’s, or is it still a solid unit? I have the 3.21’s and am wanting the 3.92 if it’s reasonable

Whole unit needed for front diff

Unfortunately you have to swap the whole front differential. I am in the same boat. There is a 3.92 unit on eBay for about $775 right now.

I don’t have an answer for you but man do I feel the same.

Having done gear swaps in previous vehicles, I can tell you it's just not worth it anymore. On old cars where it was easy, and re-calibrating the speedometer meant inserting a new speedometer gear into the transmission, it wasn't that bad. But now, you'll spend a couple thousand on the gears with the labor to install (or more in this case since you need the whole front diff). Then you'll need to get a tune to correct the speedometer, which with a lot of new cars requires a new computer or at least one that's been cracked into to accept a tune. I wouldn't personally want to spend the money it would take once done, let alone risk losing my warranty. The cost and risk seem to far outweigh the reward. Just my two cents.

This has been covered in 100 other forums. Just use the search bar.

I agree that the subjet has been covered before may times, but the replies are about if is it worth it or not, cost wise, and alternatives. I would like to know if anyone has done it on a 2019 and if the computer is able to cope with the swap.

100% requires the computer to be changed

other than if you tow often why would you want 3.92 over 3.21?

Acceleration. They do pull a little better when you mash the go pedal.

Did the shop have to adjust anything for your speedometer to read correct speeds or anything?
