Gear ratio

[Jim Paton]

I just blew my rear end out of my 08 gmc sierra 5.3L any idea what the stock ratio was for the rear end and any suggestions for a slight upgrade when replacing it would be appreciated.

The info on what your current gear ratio is, is literally on your truck.

Get a photo of the RPO codes in the glove box and I could tell you what gear you have. Or at least what was originally equipped.
