What if I changed my axel ratio to a 3.42? Night and day or not worth it?
They had either a 6 or 8 speed transmission in 2017. Both have a really deep 1st gear so that will compensate for the rear end ratio. If you aren't towing in the mountains regularly, I agree...leave it alone.

But switching rear ends will hurt your MPG in daily driving...which I'm betting is a lot more of your miles.
