Gear Ratio
I'd like to know whether a higher or lower gear ratio is better for towing. Considering a 2013 or 14 Silverado 2500 4wd. I plan to be in mountains as well as flats. Don't know what I'm going to tow...
Forum Discussion
When GM changed to the 4.10 as the standard rear ratio for the 2013 HD, they indicated that it was because it improved fuel economy for most lower speed driving.
