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.
The rear gear ratio of a 1989 Chevy Cheyenne truck is between 2.73 and 4.56. This is the number of times the drive shaft rotates in relation to the tires.
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.
Same as the rear.
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.
Depending on the differential gear ratio, anywhere from 17 to 19 mpg.
You can call your local dealership, and they should be able to run the VIN and tell the ratio from the sales codes.
Will a 1997 blazer what work on a 1999 blazer????? If your talking engine, transmission, or running gear than yes. It is all the same.
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 will be the same as the rear diff
It does not matter what gear it is in.
