Axle Details

The Dana 70 axle has been around for decades and is commonly found under full-size GM, Dodge, and Ford trucks. The axle is available in both front and rear applications and features a large 10.5" ring gear. Standard D70 models have 30 or 35 spline axles, however, the Dana "Super" 70 is the holy grail of the series with massive 37 spline shafts. Dana 70 axles look similar to the D60 and D80 with a 10 bolt asymmetrical cover with a fill plug on the axle centerline, however, the easiest way to spot the D70 is the "70" cast into the housing.



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