The Eaton HN180 is a lock washer used in Eaton differential assemblies. Lock washers at this level of the drivetrain serve a critical retention function, securing fasteners against loosening under the vibration and torque loads typical in heavy-duty truck axle service. If you are tracing a differential repair or rebuild and need to confirm HN180 is the correct part for your specific Eaton unit, give us a call at Pro Gear and Transmission and we can help you verify the application before ordering.
