Dana 60 and 10.5 Sterling one ton axle set from an '03 superduty. Axles are 100% complete caliper to caliper. Front is high pinion, driver's drop and the sterling rear is a 35 spline factory disc brake model. Both axles are currently 3:73 ratio. Beef your ride up with these and stop exploding your stock axles!! I have two sets of these axles and don't need this set. Axles are located at my shop in Walhalla,SC. Price is $1400 for both.
