This is a genuine Dana/Spicer 4X4 outer stub axle for Dana 60 Dodge 2500 and 3500 front axles from 1994-1999. This can be used with or without ABS. The tone ring can be transferred from your original axle. This axle is the same as 46901. The only difference is this one comes with the dust shield already on it. These are 33 spline where they go through the hub assembly. Please note that the slinger is now packaged loose in the box. Shipping is a flat $10.00 in the continental U.S.
