Riddler Dana 30 Diff cover
Very nice cover. Bolts are recessed and the cover is a very low profile. It worked great on my Jeep XJ Dana 30 4.88 with ARB , with no clearance issues . It’s thick cast with a smooth profile. This came recommended by a friend and it worked perfectly. I couldn't be happier with it.

Tough and smooth
Very good quality- I have had the matching one on the rear axle for years. Very strong. The fill port is higher than my OEM differential cover. "Overfilling" maybe isn't a good thing?

It really CAN take a bullet
At first, I was leery about spending so much cash on a diff cover. Once I received this part, it no longer mattered. This cover is ARMOR for the front pumpkin. The piece is incredibly thick and heavy. The mating surface to the axle housing is perfectly machined, and there wasn't a single burr or imperfection in its surfacing or mounting. So far, I've rubbed this cover over some fallen timber, and smacked it once into a rock outcropping. It won't even chip. With the elevated and recessed oil-fill plug hole, I don't even think about my pumpkin as a weak spot anymore.

5 Answered questionsQ: Will this fit on the Aluminum D44 Rear 1996 Grand Cherokee Limited Answer this question
A: Jason, unfortunately we don't offer a diff cover for the 96zj Jeep. Thank you for our question.
Answered by RK on 04/02/2015
Q: I have a 86 cj7 with the thicker tie rod 1.25. Will I have an issue with clearance on the Dana 30? Answer this question
A: Hello It sticks out just the added thickness of the cover which is 1/4 inch more. Turn your wheels all the way left and right and check your clearance now. If you have more than 3/8 of an inch you will be ok.
Answered by Rody on 09/20/2014
