Good evening to all. I have a 2013 ATS 3.6 Premium rwd....just wondering if anyone has or has heard of anyone who has swapped the rear out. Just looking for a little more get up and go without doing engine mods or power adders.

I've heard theres like a 3.42 or maybe a 3.45 rear? Would it just be a bolt in and tune? How would I find one?

Don't want to go down the road of just swapping ring and pinion, been down that road and they never last, just want to swap out a factory rear basically.

another option would be to get the rear end from a manual car. It comes with 3.27 gears, but it has an LSD, which makes driving so much better.

Sadly the 3.73 from the V will not communicate, something about a built in pump or cooler or something.

Turns out Overkill has a supercharger kit for these models so....time to start saving ; )

Thanks for all the input.
The V uses the E-diff that comes with the SS 1LE camaro, CTS-V, CTS V-Sport and ZL1.
It is electronically controlled instead of the traditional friction controls.
