Hello everyone...I am new to the forum and new to Dodge/Ram all together. Yup, you could be talking to the newest convert from GM. Next spring I am likely going to be ordering a new 2017 Ram Laramie 2500...Cummins of course! I will be installing a 6" lift and 37" tires shortly after bringing her home. What do you all think about what gearing I should order in the truck, knowing I am going with the 37's? Is the standard 3:42 going to be good? I want optimum fuel economy and power for the setup. Thanks in advance for your input.
