5th Gen Ram Tech2019+ Ram Trucks: This section is for TECHNICAL discussions only, that involve the 2019 Ram 1500.. For any non-tech discussions, please direct your attention to the "General discussion/NON-tech" sub sections.
Does anybody know how to determine the rear axle ratio of 2019 Ram for certain? It could be a 3.21 or a 3.9, but I can't tell for certain. I want to pull an 8,995 GVWR travel trailer and I could be over capacity with the 3.21 ratio..
Ratio should be on a tag on one of the rear diff cover bolts..... Or, go here, feed it your vin (all caps please), and that will tell you what it came with from the factory. May also be on a sticker under the hood somewhere...... but, I've never been able to find that one.
