Rear end replacement
I have a 2007 LTZ with the 3.43 rear end. I have a 4200lb travel trailer and a few people told me I am going to have some trouble with it. I wonder how difficult it will be to find a 3.73 rear end and have it installed. Any guesses?

I think I'll be OK too. Most of the guys that are telling me this have chevy HD and cummins blah blahs with stroker this and that's. They are just used to hauling like there's nothing back there. I just think mountains will be a little painful.

If anything, a 4.56 will HURT gas mileage....forgetting the debate about 'sweet zone' for 4 cylinder mode, the higher the gear ratio, the more acceleration and the worse the fuel consumption. At higher speed, the higher gear ratio will be turning a couple hundred more RPM thus getting worse gas mileage. In the city, no doubt higher ratio will mean worse gas mileage...Another thing to consider...some higher ring and pinion combos 'whine'.....
