Re: Stock Rear Axle Gearing
Only way to know for sure is to look at the ring gear and see what the stamp says. You can also do the roster tire and count driveshaft revolutions. Just make sure to chock your front wheels before hand as you are putting the trans in neutral to do it. Most 3/4 tons I’ve seen are 4.10 or 4.56. But over the years the ratio could have been changed.
