Eaton NoSpin automatic locking differential for Clark axles with 39-spline gears, carrying a 9876 Nm torque capacity and backed by a 1-year warranty. Most gear oils are sufficient - a quality petroleum-mineral-based oil is recommended, and synthetic oils or friction modifiers can also be used, though they aren't necessary; in cold weather, a lower-viscosity gear oil (equivalent to API GL-5 75W-90) is recommended.
