Dana 60 Front/Rear Axle

Dana 60 Axle, Differential Specs & Information

The Dana 60 is a heavy duty, full floating differential used by Ford, Dodge, and General Motors in various pickup applications over the course of several decades. Jeep also used the Dana 60 in select J truck applications. The primary application of the Dana 60 has been in 3/4 and 1 ton pickups as both a front and rear differential. General Motors began phasing out the axle in 1988 and completely replaced it with an IFS system by 1991. The Dana 60 was also used in the Chevrolet and GMC "Quadrasteer" models from 2002 - 2005, but rather than standard universal joints, the system required CV (constant velocity) joints.

Ford has used the Dana 60 considerably since 1955, and continues to use it in some HD applications. The Ford Dana 60 has a driver side drop and reverse cut gears. Front axles used kingpin steering knuckles until 1991, when ball joints became standard. Most Ford Dana 60s and all 2005+ Dana 60s have 35 spline axle shafts. Dodge used the Dana 60 until 2002, as the 3rd Gen (2003-2007) Dodge Ram used AAM axles. Early Chrysler Dana 60s used a passenger side drop, standard rotation gears, kingpin knuckles, and 35 spline axle shafts. Later models used ball joints, a driver side drop, reverse cut gears, and 32 spline axles (though the 2000 - 2002 models retained 35 spline axle shafts). Ford and GM have always used standard locking hubs with their Dana 60 front axles, while Dodge used hubs until 1994, when they switched to a CAD (center axle disconnect) system (some 2002 model Dodge Rams are an exception and in fact had locking hubs).

The Dana 60 is praised for its brute strength and full floating configuration, with the kingpin front axle being the "Crown Jewel" for off-road rigs. At 500 lbs, its biggest weakness is its sheer weight. All early 60s were made of gray cast iron, while late models have been produced from ductile cast iron (the cut-off date is unknown). Dana suggests that the factory axle is rated for a maximum 38 inch tall tire. A semi-floating version of the Dana 60 exists, but is extremely rare - its GAWR is 5,500 lbs. A stronger variation of the Dana 60, called the Dana "Super 60", was used in the Ford F-450 from 2005 to 2012. It had larger 3.75 inch, 0.50 inch wall thickness axle tubes, a larger ring gear, thicker pinion shaft, bigger universal joints, and 35 spline axle shafts.
