I'm thinking of adding a front differential lockonto my 2020 Ram. However, I've read a few posts where people say that beginning with 2019 the differentials on the Rams were different from those used in say a 2015 model. However, I see that they still use AAM 9.25 axles for the front and AAM 11.5 axles for the rear, which are the same as the older models, correct? Or do they have something different?
