    I don't think you'll even notice 3K lbs behind you :favorites13:

    That was a smoking hot deal on that truck.

    Enigmatic VIN results r/t rear end gear ratio

    Looking up my VIN on a link obtained at "DodgeForum.com" as opposed to a Chrysler site (that seemed impressively official) gives me 3.21 on the former and a 3.92 on the latter. I can't seem to make any links from this forum work and was wondering if there are any visible differences between the two. I am towing a tandem axle trailer, electric brakes, and a weight around 5500-6000lbs wet n loaded.
    The higher ratio will have me right at limits while the lower ratio gives (a little) margin.
    Thanks all!

    Is the tag on the axle gone?

    Thanks. But where did you find that? OR is 3.21's the standard and it only shows up if there is a different ratio?
