It's not hard to install, but my suggestion would be, if you remove all the bolts and it starts leaking, to pull the cover, re-seal it and fill it back up. Too many times have I seen diff covers leak because of someone adding diff armor and not resealing the cover. It turns a 10 minute job into an hour job, but might save you a headache down the road.

The Shrock armor can take a pretty good beating.
