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.
The stock gear ratio for a 1995 Chevy Blazer is 3.73. This provides a good balance of fuel economy and power to the rear wheels.
Call a Chevy dealer and ask for parts dept. and give them the VIN# and ask them what the gear ratio is and they will tell you.
it will probably be 3.73
Same as the rear.
what size truck? 1500,2500,3500?

i believe it would be 3.11
I have a 2002 Blazer with the 4.3L engine and 3.73 differential gear ratio, it gives me 17 mpg on average.
You'd have to look at the RPO code in the glove compartment to determine this, as there were a couple different options. The gear ratio for the front and rear axle will match.
the stock Toyota gear ratio is 4.11
Hear is an easy way to find out what your truck has in it FOR SURE. Wright the VIN # down and call a Chevy parts dealer and tell them that you have the VIN# and would like to know what the gear ratio is in your truck.
