They absolutely suck the life out of your truck and its fuel economy as soon as you put a load on the trailer. they also shorten engine life. I would like to smack the pencil-pushing complete idiot who came up with such a horrible idea in a big truck up side the head with a hammer.

I don’t know enough yet to understand what the best rear end ratios are or which ones are bad. That sucks mine are bad. Guess I can’t change that though without spending a fortune.

Since you have a 13 tranny, my choice would be 3.70
