2008 Silverado 1500 Axle Ratio
Been under my truck for FAR too long and can't find an axle stamp. I need to know what axle ratio I have so I know what my truck is able to pull. Via my manual I found out it's either a 3.45 or a 4.10. Where can I find out what my ratio is?

What kind of highway mileage do you get? If you get decent mileage, you probably have the 3.45. If you get bad gas mileage, it's probably the 4.10s.
Also, it may be helpful to post your engine/vehicle submodel.

Check the spid label in the glove compartment.
