    I was wondering where can one get all the specs on a truck they purchased?

    I'm talking about:

    Axle ratio
    Ring gear
    transmission gear ratios

    Thanks, but all the VIN decoder told me was what I already knew:

    Made in Silao, Mexico
    It is an LTZ
    It is 2WD

    Try to look up the RPO codes. Their may be a list on the site.

    Here is the list and like @Colan Rose mentioned above, the codes will be in your glove box. If you are having trouble reading them, as they put a ton of information on a very small rectangle, take a picture. That's what I did and saved a ton of time from having to write them down and trying to read them.
