3.08
Look on the sticker in your glove box:G80 Differential, automatic lockerGT4 Rear axle, 3.73 ratioGT5 Rear axle, 4.10 ratioGU6 Rear axle, 3.42 ratio
To check the rear axle ratio on your Suburban, you need to safely jack up the vehicle to get access to the the rear axle. Then there should be a metal tag on one of the bolts on the rear axle cover indicating the axle ratio. The ratio varies with different options and load capacities, so it's not the same for all Suburban's.
All depends on what you are wanting to do. Be more specific in what you are wanting to do. Are you wanting a ratio to tow or haul something or are you wanting great mileage?
depends on the options chosen at purchase, call g.m with axle number
That is done through the dealers computer system. There isn't one specific digit in the vin for the axle ratio.
