Review on 🔩 Enhanced Performance Differential Cover for DANA 30 by ARB Products by Robert Pearson

What you get: Ductile iron construction, recessed bolts, removable dipstick and drain plug. There are many options for aftermarket cases, but for me the release of this case was a benefit. It's hard to take serious damage, but not so bad that you have to mod the entire frontend to make it work. In comparison, this is one of the thinnest lids on the market and works well if you don't want to spend a lot of money modifying everything else around the lid. I don't drive my truck in mud at all, so it was important to me to keep the factory look and feel. I just wanted a shroud that wouldn't buckle when hit by snow and ice in the Midwest, while also stiffening the axle housing. I liked this cover. The purchase is very satisfied. A word to the wise, do not install this cover on an XJ with a factory (non-raised) front end. It installs on level pavement, but if the front end is compressed, the chain will flex as it hits the pavement. An easy way to fix this is to put 1.75" washers on the spools and then insert a 2" coil spring insert into the spool so that the factory front bumper hits the spool's polyurethane insert before the tie rod ever touches the cover. That way you still keep the factory ride feel and near-factory look.
