: Is there a way to tell which rear end a suburban has by looking at the VIN number or some other number that comes with the car?I'm looking to find out if certain vehicles have a 4:10 rear or a 3:73 . I want a 4:10 for towing .
Look for the RPO codes in the Glove box, check out the following web site;

Look for the starting w/ GU4 - GT6, these are the axle ratio codes, G80 = Eaton Gov Lok locker. Hope this helps. R/ Al in SoCal
