What differential gears are out there?

I've been doing some reading and it's a bit confusing.
I have a 2014 MT. I *think* that means I have 4.10 gears.

Are all the pre 2017 MT and AT cars the same 4.10?
And is it 2017+ that goes to 4.3? For AT and MT?


I need something different. Quite frankly, I dont care which way, as I'm currently bouncing off the rev limiter about 150ft before brake points at half the turns. So a little bit taller would be fine, or a good bit shorter. I'm willing to bet the extra shift with shorter gears will offset the the extra gearing from a shorter ratio, so I doubt there's much performance either way.


Thanks!
