Easily installed with supplied hardware but do your homework on required torque specs for the bolts.

I recently installed the Dana 30 cover, and overall, I’m quite pleased with it. The cover looks great and has a solid fit. The drain plug feature is especially convenient and was a key reason for my purchase, as it makes fluid changes much easier.However, one area where the cover falls short is the quality of the fasteners. They seem to have skipped the heat treating process with them so they are very soft. To avoid any issues with stripping or snapping, I’d recommend purchasing a separate set of quality fasteners for the install.

I did not use the supplied bolts - did not want to take a chance after reading all the other reviews. Used the LubeLocker gasket (can’t beat it). I was overly shocked that they are ver silver and not dark at all as the pictures appear. So a little prep and I painted it black with some epoxy paint. 99 Jeep TJ

Heavy duty and well made. I bought stainless steel plugs on Amazon because they look better.

This is a serious diff cover. Heavy cast steel. Looks great on the vehicle. Perfect fit for a 2004 Jeep Grand Cherokee 4.7L limited with Quadra Drive.

I installed this and the D44 cover on my 2014 JKU and they look great! I had no issues with clearance of the tie rod or track bar. The quality of the covers is excellent, bolts are included as well as a reusable gasket. Take your time to carefully and thoroughly clean the diff surface before installing, I have had no leaks. I like that these include two fill locations and a drain, but especially that they are made by the same folks that make the OE axle assemblies.

Cover seems beefy and strong but included bolts are garbage. Snapped one in the housing while trying to torque them. Returned along with defective and broken bolts.

These covers are beefy and look great on our Jeep. Discovered the original rear cover flange was bent at the bottom where we slide over a rock. I was surprised it wasn’t leaking. My differentials on my 2017 JKU already have drain plugs, so the ones on the covers will not be used. I read reviews were people said they weren’t black even though the Amazon picture looks black. I lie, the hammered gray look of them. I had no problems with the bolts. Cranked down on them as if they were a standard cover. The new bolts are slightly longer than the old bolts. The included gaskets are rigid and so far no leakage.Only Con: inside the cover the metal goes up to where you would not be able to drain all the oil out when changing without removing the cover.
