There isn't a specific digit for the gear ratio. The last nine digits are vehicle specific, the dealer can input those digits in their computer system to get the build list of the truck. The ratio will be listed there.
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.
There isn't a position that tells the gear ratio. The dealer can enter the VIN in their computer system and pull up the build codes to see what ratio it was built with.
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.
Depends on the gear ratio, power-to-weight ratio, and drag coefficient of the specific truck.
Rear end ratio: 2.82
Most were 3.55:1Most were 3.55:1
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.
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.
