There are four ways to find a ratio.
1 A dealer can normally tell from the vin number.
2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement
info.
3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.
If you call a GM dealer and give them the VIN# they can tell you what gear ratio you have.
It should be a 342.
All you need to do is call a Chevy dealer and give them the VIN# and asked them what the gear ratio is in your truck and they will tell you what the factory gear ratio is.

It's not. Call a GM dealership, tell them your VIN #, and they can tell you the gear ratio it came with from factory.
Most any stock carrier without a posi with have a 2:73 ratio
If your asking about the gear ratio, Then write the VIN # down and call a Chevy dealer and ask for parts. Then ask the parts man if he'll tell you the gear ratio and that you have the VIN# on you truck. He'll tell you what the gear ratio is from the factory.
Probably not. The factory wouldn't know the differential gear ratio.
