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...

Gotta get me one of the T-shirts to be sure....:)
If I'm not mistaken, I thought the Duramax/Allison combo comes with the 3:73...can tow a lot of weight, has low end TQ and still get's pretty good mpg.
As far as 4:10, which is what I have, it gives you more gross combined weight..the truck and what you tow can weigh more than with a 3:73, 3:42 etc...
The way I understand it, the 3:42, 3:73 would give better mpg than the 4:10 would...I'm use to a 4:10 so it doesn't matter to me...But there are Math equations that show you tach lower with the 3:42, 3:73 than with the 4:10 when empty or towing, thus, higher rpm, would equate to using a little more fuel, but would allow for heavier towing...(if trucks GVWR can handle pin or tongue weight).
4:10 isn't as "economical" as the 3:73, 3:55, 3:42, but they have a less GCWR than the 4:10 gives one in an identical truck....
hope this helped......
