I agree it's ambiguous, and somewhat complicated with a shared application. For S&Gs, I just looked on Amsoil's website for a 2023 Ram 2500 with 6.4 gas. https://www.amsoil.com/lookup/auto-and-light-truck/2023/ram/2500-pickup/6-4l-8-cyl-engine-code-j-esb-j/
There's a lot of listings for Ram rear differentials, and too early in the morning to dig into the variants. But there's a big difference in fluid volume called for between them and GM applications, assuming it's the same axle assembly.
So, if GM differentials tend to be underfilled, what does everyone think about a 7 pint fill, as opposed to the 6.3 pints listed on Amsoil's website? It would somewhat conservatively split the difference between Ram and GM specs.
Thanks for the reply’s everyone. I will try to find the alignment printout and post that up. Sounds like I’ll be taking it back to have the alignment re-checked
Can I ask if you are having issues with the current coils?
With all of my years around LS engines, the stock coils are the best hands down. If they aren't giving you any problems, do no change them. They can go 200-300k miles easy without a hiccup.
