I have a 2006 Duramax 2500, with the 6-speed Allison tranny. How can I find out what my rear axle ratio is?

 

Gimme the vin if you can,I'll look er up

 

Thanks! here it is:

1GCHK23D06F177211

I didn't know you could get that info from the VIN. I knew engine size and that stuff, but axle ratio? I thought that was from the data plate only.

Oh well, thanks again!

 

You can get it from the codes in the glove box also, they are the ones that start with G

 

Here is the build sheet...its a 3.73
