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.
