ROCK HARD 4X4™ HARDHAT™ DIFFERENTIAL COVER RED FOR FRONT/REAR DANA 44 [RH-9051]
this is what i used, you can get it in black as well. i have the RVC front axles and the turning radius with these axles is limited due to the tie bar hitting the stock diff cover. the point is if you install a full diff cover it may reduce the turning radius even more.
I wonder if some of those covers needs a baffle in the diff. I did the ox lockers and had to add the baffle to the rear. Looking at the stock cover it has one built in on it. The ring gear throws oil towards the cover on the front diff, on the rear It throws it towards the vent. Some thing to keep in mind when changing the cover.
