Owners of 2012's with 37's , a question for you?
Haven't really measured it, but I do know it has gone down. 4" Teraflex with 37's and stock Rubi 4.10 gears. I used the AEV Procal to adjust the shift points and it works great. I agree with the above post though, if you are looking for the best fuel mileage then maybe you should just leave it stock. I bought my Jeep for the off road potential, not for the fuel economy.
