It should be a 342.
What is the gear ratio on a 1996 2wd suburban 1500?
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 the front is 3.55, then the rear needs to be 3.55

i have a 92 silverado 1500. put 410 gear in and took out stock 308 gear. yours is probaly the same if you have 350 engine and 700 trans.
They used a few of them. Open the cover, count the teeth on the big gear ( the ring gear ) next count the teeth on the small gear ( the pinion gear). Divide the big gear by the little gear and that is your ratio.
The most likely ratio is 3.55-1.
Probably 3.55, but there were a couple of options.
