Newer Chevy 2500HD rear diff ratios and engine differences?

Hi If you want to order your new 2500 as a crew cab, I can get you the number to call for a customer build. You come to the plant and see your truck being built and ride off the end of the line in your new truck!! It's a great experience and you get to meet all the great people that help build your truck.
