biggest issue with the stock diff covers would probably be the rear cover getting hung up on a rock and "peeling" off. they're relavitely thin metal, so there is also the possibility of denting them if you run into something that is way too tall.
i suppose a diff skid would protect the stock diff covers, but with the downside of decreasing your ground clearance. for the money, you're better off with a more stout diff cover and no diff skid. i upgraded to riddler covers and they've been great.
