Heavy duty but didn't come with hardware, which is a problem trying to use the original bolts because they are too short with the guard width. First time both front and rear leaked. Then I reinstalled with longer bolts now it's okay.
Next time I change my fluid I plan to sell the guards and install Riddler covers. So, that would be my suggestion - forget the guards and get Riddlers from Rokmen. One more thing I did wrong the first time.
rokmen.. enough said =D i paid like 210 shipped for my 30/44 dif covers, they are extremely thick and after watching the demonstration video of what kind of punishment they can take i was sold on them.. im pretty sure they got a life time warranty as well.. the fill hole is higher than on the stock diff cover as well to allow for more diff fluid to be added
and yah its been pointed out in my build thread.. my fly wasnt unzipped it was actually broken =p
99 sahara :: 2'' coils (front), jks acos f&r, jks front trackbar, jks bl/mml, RE monotube shocks, hp30/d44, 33'' procomp mts, 15x8 eagle alloy 187s, hella optilux fogs, raingler nets, & more random junk::
my vote would be one that replaces the stock cover or one that fully covers the bottom half of the stock cover. (warn) I have seen some of the one's that have slats/open spaces still get hit by longer rocks limbs etc, and put a hole in the cover.

These are all good diff guards/covers. I've seen them all on the trail I think and none of them have failed to do their job. I prefer the heavy duty covers though instead of a seperate guard but they both work.
I liked the Alloy Usa diff covers because they were 1/4" steel but also slim so the trackbar and tie rod don't interfere with it. But now that Alloy Usa is out of business I wonder if I can still get my hands on one.
I currently have the Solid design but my tie rod and track bars make contact alot. I have a d44 in the front... I mention that because d44's have more of a clearance problem with the steering and track bars than the d30's.
all aftermarket diff covers have a raised fill hole so that if you put them on the back axle and the pinion is rotated up you can still get the required amount of fluid in there. Wanted to be clear that this raised fill hole is not so you can put loads and loads of extra fluid in. otherwise the breather tube would burp up the extra fluid if you hit highway speeds. Only put in what the owners manual says and no more.
anyway, can't go wrong with any of these choices. some are better than others but I don't think any will fail you on the trails.
