The Lippert 386278 is a service replacement gearmotor assembly for Lippert-equipped trailer jacks. If your power jack motor has burned out, seized, or is drawing too much current, swapping in this OEM assembly restores factory operation without replacing the entire jack.
It's a black, alloy-steel-bodied unit sized to bolt into the original jack housing, so installation follows the same mounting points as the motor it replaces.
Verify part number 386278 against your jack's parts diagram before ordering, since Lippert uses several gearmotor variants across its jack lineup.
