How to tell axle ratio?

[Jdonoghue]

Looking at new trucks on the lot. How can I tell what the axle ratio is? (aside from asking - I have to do my looking on Sundays)

Look at the window sticker. If it is a 4. 10 axle ratio it will state so and show a price. Otherwise it is a 3. 73 axle ratio which is standard.

The sticker is in the glove box. It will tell you what is in the truck and is easier for me personally.

there should be a tag on the pumpkin that indicates the ratio. Mine is on the rear left side if I remember right.
