 and Ford. There are rear axle and four wheel drive front steering versions of the Dana 60. It can be readily identified by its straight axle tubes, 10 bolt asymmetrical cover, and a "60" cast in to the housing. Gross axle weight ratings are often lowered by the vehicle manufacturer for safety and tire reasons.

History

Ford was the first company to use Dana 60 front axles in 1955. In the mid-1970s the Big Three (automobile manufacturers) all started using this axle. GM began phasing it out in 1988 in favor of Independent suspension

, while still offering it in some higher GVWR trucks (V-30) until 1991. Dodge used a Dana 60 up to 2002. 3rd Generation Dodge Rams dropped the Dana 60 in favor of a lighter, reverse cut AAM axle. Ford still uses the Dana 60 front axle. Manufactured in both Kingpin

Big Three variations

  • GM / Chevy versions are passenger side differential drop, standard rotation gears, kingpin knuckles and 35 Spline axle shafts.

  • Dodge versions were passenger side differential drop, standard rotation gears, kingpin knuckles and 35 spline axle shafts in early models. The 2nd Generation axles were drivers side with ball joints. 30 Spline axle shafts were used instead of 35 splines, except 2000, 2001 and 2002 models which were equipped with 32 spline axle shafts.

  • Ford versions are drivers side differential drop, reverse-cut gears, and kingpin knuckles up to 1991. The later axles have ball joints. Ford Dana 60 axles mostly feature 35 spline axle shafts.

Dana 60 aftermarket

Dana Super 60

The Dana Super 60 is an upgraded version of the Dana 60 front axle.

Differences in the Dana Super 60 versus the regular Dana 60:
  • Larger and thicker diameter steel tubes (3.75 inches diameter and 1/2 in thick)

  • Larger ring and pinion which increase the contact area and overall strength.

  • Larger Universal Joints which increase strength and steering angle.
  • Super 60s use 1550 Universal Joints.

  • Net formed spider gears for increased strength.

  • All made with 35 Spline axle shafts.

This axle was used only as a medium duty unit until the
Third Generation F-450 Pick up began production. The Third Generation F-450 pick up is a light duty truck. This axle is still used in the medium duty F-450 and F-550 4x4 trucks as well.

Dana 60 rear axle

The Dana 60 rear axle was first introduced in 1955 as a full floating axle in Ford F-250's and is still used today.
  • Manufactured in both full float and semi float variations. The semi float axles have GAWR

     up to 5,500 lbs and the full float axles were rated up to 6,500 lbs.

  • Full floating, 30 Spline, variants are common. 35 Spline semi-floating and full floating axles exist, but are less common.

Dana 61

A variation of the Dana 60 known as a Dana 61 was made to accommodate gear ratios that allowed for better fuel mileage. This was done as a direct result of the 1973 oil crisis
1973 oil crisis
The 1973 oil crisis started in October 1973, when the members of Organization of Arab Petroleum Exporting Countries or the OAPEC proclaimed an oil embargo. This was "in response to the U.S. decision to re-supply the Israeli military" during the Yom Kippur war. It lasted until March 1974. With the...

. A 3.07:1 gear ratio was common for these axles and unachievable in a regular Dana 60. To allow for the different gearing, the Dana 61 had a greater pinion offset. This offset meant that a different carrier and a different ring and pinion had to be used. The Dana 61 was made in semi-float and full-float axles for select 4x2 Ford 3/4 Ton and 1 Ton Pickups and Vans from 1974 - 1987. A Dana 61 front axle was selectively used in Dodge 4x4 3/4 Ton and 1 Ton pickups from 1987 - 1993. Although 3.00:1 and 3.07:1 gear sets are possible from a Dana 61, lower gear sets (4.56:1 on down) are not.

Dana 53

The Dana 53 first appeared in the late 1940s and is much like a Dana 60. Although all Dana 53's are semi-floating, rear axles. The Dana 53 was phased out in the 1960s by the Dana 60.
