VIN

[gil01]

I have a 2002 2500hd with the 8.1 liter big block. I bought it used with only 3500 miles on it. The question I have is will the VIN tell me what the axle ratio is? The guy I bought it from said it is the 4.10 ratio but I want to be sure. The VIN is 1gchk23g02f199391. Thanks for your help!

Look in the glove box at the RPO codes.  If you see a GT4 then it is a 3.73 gear.  If you see a GT5 then it is a 4.10.

If you cannot find the build sheet do what I did, I went to my local GM dealer (Canadian)and with my VIN # they gave me a printout of the RPO's for my 96 GMC 2500HD.

That truck was built 3/11/02 in the Flint, MI assembly plant.  Axle code is GT4, 3.73.
