Yukon Rear Nodular Iron Differential Cover for 8.5" GM with 5/16" Bolts (YHCC-GM8.5-S)

The only issue that I will start by noting is that I had to go somewhere other than Amazon to buy mine because if I didn’t have bad luck with my purchases then I wouldn’t have any luck at all. But moving on, these bad boys are the most hardcore, high performance, high durability, great looking differential covers that money can buy! I originally bought a Rancho RockGear diff. cover but the only thing you’ll save on between the two options is weight, and that’s because the Rancho diff. cover is only as thick as a piece of construction paper. The Yukon covers are thick, durable, engineered perfectly, and built to last! I’ve now got less noise out of my axles and know that they’re protected on the trails. The fill holes are perfectly placed, nothing leaks as long as you use a new gasket during installation, and the magnetic plugs are an added feature that I truly love as well. They are pricey but if you take your rig anywhere that those covers might get hit, then it’s still going to be cheaper than buying a whole new diff!

Picked up a used 2010 wrangler that needed some refreshing. Wanted to change diff fluid. Why would ANYONE put on a rusty oem diff cover that needs to removed, re-sealed with a gasket/RTV anytime you change fluid? With this incredibly THICC cover (I mean like weighs like twice as much as original plate) a convenient drain plug makes easy work for fluid changes. TWO fill plugs giving you much more custom filling options. And a clean AF look. A worthy upgrade for a reasonable cost. Have it on my Dana 44 and plan on the Dana 30 version when I find the time.

As I was in the market to upgrade my rear diff cover, I decided to go with the one made by Yukon, being that it was a 10 bolt rear, it was a perfect choice, its fit well, it’s a bit on the heavy side, but you know by the feel, it’s made well and can take beating and some more. *Bonus, if you run an aftermarket panhard bar like I do, this diff cover doesn’t interfere with any clearance issues*

Much better than removing the cover and the stock fill plug just to change the rear end gear oil on my 04 Tahoe. Would definitely buy again, especially for my new to me 2001 GMC Sierra 2500HD.

I love this product. It really makes my front and rear axles look good. They are strong, easy to paint (If you sand them and prep them properly) and to install.However! Please don't make the mistake I made because I watched a youtube video on how one person installed this. The person in said video did not use thread sealant on the drain and fill holes. So naturally neither did I.Big mistake! Please use liquid Teflon on the threads of the fill and drain plugs. Or like me, you will have leaks. Especially if it is hot outside. And yes i tightened it till they were snug but they kept leaking. So I kept tightening after every drive and inspection if it was still leaking. Well i tightened them till they would not tighten anymore. Still leaks. Note the leaks are not from the large gasket area but from the fill and drain plugs.Oh and please only fill to the first fill hole and not the higher second one. Once it starts to spill from the 1st lower fill hole, you are good to plug it. but like mentioned above, use thread sealant!Great product, my mistake on the install gave me problems.

Fit perfectly, I painted mine red and left the logo in black. Looks great

This is a high quality aftermarket differential cover. I inadvertently ordered the cover for a 10 and 1/2 in ring gear in the 14 bolt rear end, my truck has the 11 and 1/2 in ring gear so this would not fit. I needed one quickly so I had to Source One locally that wasn't as high quality (the one I got locally was just a standard sheet metal one) I believe if I would have ordered the correct one which would have been the one for the 11 and 1/2-in ring gear I would have been very satisfied with it because it was a high quality part.

A must upgrade to the rear Dana 44 axle on a 2017 JKU

Description says 3/8" bolts however the ones I received are 5/16" and do not fit....Fantastic cover! but had to buy all new bolts

Es exactamente la medida de la tapa, muy gruesa espero que resistente para las competencias en las rocas, me agrada que tenga varios tapones de drenado y llenado, así cuando tenga que cambiar el aceite ya no sea necesario quitar la tapa

Seems like a quality product. Stronger then a stamped steel diff cover. bolt right. Also dont need high steer to fit cover unlike some other diff covers.

Very beefy and strong, highly recommended
