BD-Power Rear Differential Cover AA 14-11.5 03-18 Ram / 01-19 GM

Keep your rear end looking cool and RUNNING cool with this replacement rear differential cover from BD!

No, not all aftermarket differential covers are created equal. Most aftermarket differential covers are excessively large, resulting in lubricating oil being literally flung OFF the ring gear, exactly the opposite of what you need. BD's design deflects oil back onto the ring gear and into the pinion gear, resulting in a cooler, longer life.
