Reviews: Riddler Cast Iron Differential Covers

Perfect fit, no leaks.

The fill plug it came with was non metallic. It also was a different shape, requiring a tool. Ended up reusing stock fill plug. Otherwise I'm extremely happy with quality and craftsmanship of the cover.

Heavy duty replacement cover ready to paint included all hardware and RTV. Much more robust that stock (which I am replaceing due to pealing on rocks) I can't see this cover pealing or being punctured by rock or bulldozer the hardware would break first, all 10 bolts. Cast no seams nice workmanship and a tiny skull what more could you want.

I hung up on the ledge of the OEM cover and popped the rock out of the ground smashing things, this cover has no ledge so that fixes that problem.

Fit really well. The angled fill hole allowed filling with gear lube bottle directly with no hoses or anything else. Slight increase in fluid capacity from the OEM cover. Cover seems very durable.

The fit and finish of the product was great. It bolted right up with no issue at all. Te stainless hardware is a great bonus.

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.

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?

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.

Easy to install a must have to protect your lockers. This housing will not fail you. Built right.

Bought diff covers for both the front 44 and rear 60. Both are heavy duty, they came ready to paint with all needed hardware. I can't wait to get them off road and put them to the test I have no doubts they will take a beating and protect lockers and gears.

Very nice product.

This diff cover is awesome, especially when painted. It is well worth every penny. You will see why as soon as you hold it in your hands.

Beefy cover. Comes as a raw casting so it will need to be painted to prevent rusting.

These covers are extremely heavy and well made! Worth the buck! Also easy to paint! They are tuff took a beating and still are holding up way better then the factory ones!!

The cover is heavy duty, designed well. Nice stainless hardware and raised filler plug is an added bonus!

I like the design and looks of the covers but, post casting cleanup of the iron is left lacking. Mine came with very uneven and deeply gouged grind marks around lip. Large sharp edge over cast on the other and some bolt hole faces with casting so uneven that a bolt torqued to spec will likely snap due to uneven load distribution. Some bolt holes were machined flat, but again poorly executed. Two covers were shipped in the same box one stacked on the other. The top cover's gasket face was messed up from sliding on top of the other. That will have to be filed flat again. The covers I received will require further processing before they can be installed.
