68 Chevy car
Supply the vehicle identification number to the nearest dealer and he/she can tell you what ratio you have.
It doesn't work that way. The gear ratio determines what speed the vehicle is running at when in the (torque) powerband.
depends most chevys came stock with 2.89:1 ratio in the dif. however the easiest way to find out exactely what our vehicle has is to remove the dif cover plate and count the teeth on the ring gear, write that down, count the teeth on the pinion gear write that down and then divid the ring gear by the pinion gear. it is called "driven divided by drive" an example if your ring gear had 37 teeth and your pinion gear had 9 teeth, it would be 37/9 which is 4.11, so you would have a 4.11:1 gear ratio in your dif.
Well, an exact number will depends on your RPMs at idle, the gear ratio of that first gear, the gear ratio of your rear end gear, and tire size. Generally, five MPH or less.
the gear would be 3.55
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.
That is a 4:10 gear ratio. Just divide the number of teeth on ring gear into the number of teeth on the pinion gear and then round it off and that will be the gear ratio.

Write the VIN# down and call a Chevy dealer and ask for parts. Then ask the parts man that you would like to know the gear ratio on your year truck and that you have the VIN#. Then he will tell you what it is.
The gear ratio of a train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the velocity of the output gear. The gear ratio is very important when it comes to physics.
A good way to get the final drive ratio with the tires you have on the vehicle is to raise the rear tires off the ground. Put the vehicle in neutral, mark the drive shaft, then while rotating the tire one full revolution count how many revolutions the drive shaft makes. that would be the final drive ratio. drive shaft revolutions over 1 so three and one third revs of the drive shaft to one rev of the tire would be 3.33/1 or 3.33 gear ratio. note if tires are larger than stock or smaller than stock it will change the actual drive ratio. Or you could remove the differential cover and count the teeth on the ring gear and the teeth on the pinion gear then divide the ring gear number's (larger number) by the pinion teeth number (less teeth) to find out the exact gear ratio. I would think it will be somewhere between 3.08 to 4.56
You can call any GM. Dealer and ask for parts. Then tell parts man you would like know the gear ratio in your truck and that you have the VIN #. And he'll tell you the gear ratio. So write your VIN # Down and call them.
