How do you determine the gear ratio on a 1994 Z71?

Crawl under the vehicle and write down the number you find on the rear axle housing. Any GM dealer can provide the ratio with this number. You can also do it the old fashion way. Jack up the car, put the transmission in neutral, rotate the wheel 360 degrees and count the number of times the drive shaft turns.
