"High Fill" differential covers aren't the same as "High Capacity." The fill hole on aftermarket covers is raised higher to make filling easier rather than to increase capacity.
Unless specifically instructed otherwise by the diff cover manufacturer, fill with the same amounts recommended in the Owner's Manual and Factory Service Manual. An overfilled differential will leak oil through the seals and the vent tube.
