The differential is the lowest point on the axle and the first thing to meet a rock. A factory cover offers little protection and no deflection, and a dented cover can mean a leak far from help.
The Rock Hard 4x4 HardHat puts 1/4in plate steel over the factory Dana 30 cover, with angles that deflect hits and space between the guard and the internals. A laser cut opening keeps oil changes simple. It goes on with hand tools in minutes, so you can drive the rocky line without listening for the next hit.
