Axle Details
The Dana 80 axle is commonly found on full-size Chevy, Ford, and Dodge trucks and features a massive 11.25" diameter ring gear and 35 or 37 spline axle shafts. They are only available in full floating rear axle configurations and, although they are some of the strongest axles you can find, there isn't much aftermarket support other than a few ring and pinion sets and a handful of lockers. Dana 80 axles look similar to D70 and D60 axles with a 10 bolt asymmetrical cover, however, the easiest way to spot them is to look for the "80" cast in the differential housing.


Important Note: Some Dana 80 axles with 3.73 ratio gears use a high carrier with "thin" 3.73 gears.


Note: This axle has a Carrier Break and gear changes may require a different carrier or thick gears.
