How Many Splines Are On Your Dana 60 Axle Shafts?

Dana 60 axles are most commonly found with 30 and 35 spline axle shafts, however, 16 (pre-1978), 23 (Mopar), 32 (Ford E-350 van), and 33 (GM Express Van) spline axle shafts were offered in specific applications. Unfortunately, the aftermarket support for these less common spline counts is significantly limited so we've listed 35 spline upgrade instructions on those pages.

Many vehicles that came equipped with Dana 60 axles were offered with multiple axle shaft options so going off of the year make and model of the vehicle is not a reliable way to find your spline count. If you are unable to pull an axle shaft to count the splines, we suggest calling your local dealer with your vehicle's VIN number or using our Dana 60 Bill of Material Lookup Tool.

Gear Rotation

The Dana 60 is made in three configurations:

Standard Rotation, Rear

Standard Rotation, Front

Reverse Rotation, Front

Reverse rotation front axles have a pinion located above the axle centerline making them easy to identify as "high-pinion" axles.

Carrier Breaks

The Dana 60 has a 4.10/4.56 carrier break:

4.10- Low Carrier:	3.54 to 4.30* gears
4.56+ High Carrier:	4.56 to 7.17 gears

4.56 to 5.38 "thick" gears are available to fit the lower carrier.

*4.30 gears are only available for front Dana 60 axles and these gears fit the 4.10 and down lower carrier only.

Spline Count

Dana 60 axles were offered with 16, 23, 30, 32, 33, and 35 spline axle shafts, however, 30 and 35 spline models are by far the most common.

Axle shafts for the Dana 60 came in both full-floating and semi-float (c-clip) styles with semi-float models being far less common and much less supported by the aftermarket.

Dana Super 60

Most modern Ford Super Duty trucks feature a Dana Super 60 front axle that uses a larger 10" ring gear and upgraded inner axle seals.

Dana Super 60 ring and pinion gears will fit non-super high-pinion front Dana 60 axles, although, some minor clearancing may be required.

Some Ford F450 and F550 trucks offered an even stronger Super 60 axle with an extra wide housing, 1550 u-joints, and 10 lug hubs.
