Your cart is empty.The new red powder coated alloy USA boulder aluminum differential covers are constructed from a356-t6 cast aluminum for strong impact resistance and feature a precision machined sealing surface, allowing gaskets or RTV sealant to be used for a leak-free seal. Each cover is designed to help protect internal components from damage caused by contact with rocks and other terrain off-road as well as aid in dissipating heat from differentials. These covers also come complete with a magnetic drain plug for protection against costly damage from metal particles that can accumulate in gear oil and include a specially designed dipstick bolt to help Jeep owners avoid under or overfilling their differentials.

Idk what cover this vehicle is for, but it’s not for either axels on my 04 Jeep Grand Cherokee overland. Now it sits as a paperweight.

This thing is great, heavy and seems to be durable, no trail time yet but no leaks with lube locker. Highly reccomend this brand and lube locker, do yourself a favor and grab a pump!

I went with this cover based on the fact that it closely resembles the shape of my original steel cover which if you watch Gale Banks (5) video series on diff covers this means that the lube flows the way the engineers originally designed it to in this diff. I wanted a cover to replace the original just to add a little strength to the case and as a plus it looks good. Jeep XJ Dana 44.

I love this product because:1.) It is made of Aluminum, super strong, and light2.) Magnetic drain plug to catch any metal floating in your diff3.) Looks awesome and has a great power-coated finish4.) Won't "peel away" like the factory cover when off-roading5.) The dipstick is a MUST have for me because I installed outer Axle tube seals which could conceal in inner seal leak. I check the dipstick every time I service my Jeep. This is my favorite feature of this diff cover and at half the price of most competitive covers with this feature.6.) Great quality hardware included (minus the RTV- I used the lube locker gaskets and highly recommend them over RTV)7.) ***The brilliant product dev team at Alloy gave this product a solid upgrade over the original design. The new drain plug on the bottom is a flat recessed alley screw now! (The current picture from the seller shows a bolt with a head which concerned me as it could be a fail point scraping over rocks). The new design removes this potential fail point. (See my attached Pic). I purchased my product in March of 2020, so I assume current shipping products have this upgrade.Bottom line- this is an excellent quality product at an amazing value!

This differential cover looks and fits great...Easy to install...I ordered one for each axle. I ordered a gasket to install with it. The gasket is highly recommended.

Fit perfect on my 2015 Rubicon Hard Rock with 44s. You definitely need a hand pump to fill but for ease of use I always use a pump. The cover I recieved was flawless as far as fit and finish. I may update this review once I move a few rocks with it. I'll probably never use the drain plug because my stock plug sits lower.

Nice cover, but the fill hole is way to high and needs to be larger to make it easier to fill the diff. I put on Ram 1500 and it is just about impossible to fill without a hose and pump.
