3. Axle Shaft U-Joint Size

The Spidertrax Ultimate inner shafts and stub shafts are made to be used with a Dana 60 size axle u-joint, 1480 series. While the shafts will accept a stock Dana/Spicer u-joint we recommend, due to the strength of the axle shafts, that a stronger aftermarket u-joint such as one made by CTM be used for the strongest combination.
