Description
Performance. The G2 Axle and Gear Dana M186/30 Front Axle Differential Cover has a design that helps cool it down better. This cover has a bigger surface and special fins that help to keep the oil temperature lower while it is being used. By keeping the oil cooler, it improves how well the front axle works and how long it lasts.
Reliable. The G2 Axle and Gear Dana M186/30 Front Axle Differential Cover can hold more fluid than the normal cover. This extra amount of oil helps to have more lubrication in the differential, which makes it work better and keeps it from getting too hot. Having more fluid capacity is really helpful when driving on tough off-road terrain or pulling heavy things.
Protection. The G2 Axle and Gear Dana M186/30 Front Axle Differential Cover gives better protection for the front axle differential. Made with strong materials, this cover makes the front axle housing stronger and more rigid. This helps protect the differential from things like bumps, stones, and other off-road dangers. It lowers the chance of harm and makes sure the axle will last a long time.
Maintenance. The G2 Axle and Gear Dana M186/30 Front Axle Differential Cover is made to be easy to take care of. This item has an easy-to-use fill and drain opening, so you can change the fluid without taking off the whole cover. This makes it easier to take care of and makes sure that the oil in the front axle stays clean and in good condition.
Installation. Putting this G2 Axle and Gear Dana M186/30 Front Axle Differential Cover on your Jeep Wrangler JL is easy and requires no drilling.
Warranty There is a 10-year warranty on this product.
Application. The G2 Axle and Gear Dana M186/30 Front Axle Differential Cover fits 2018-2025 Jeep Wrangler JL models, excluding Rubicon.

2019 Wrangler - Kurtk
Differential cover
The Differential covers are very stout and should hold up against the rocks

Review shared from G2 Axle and Gear 30-Spline Dana 44 Rear Axle Kit (97-06 Jeep Wrangler TJ, Excluding Rubicon)
2000 Wrangler - MichaelFrew
Poor set up for lugs
Seem to be good quality, installation was easy, only thing I do not like is the studs being threaded cause they tend to back out to much when trying tighten lugs even with lock tight. A poor design

Review shared from G2 Axle and Gear Dana 44 Brute Differential Cover; Aluminum (03-18 Jeep Wrangler TJ & JK)
2011 Wrangler - CamilleB
G2 Differential Cover
Love this cover. It’s super thick and durable. Holds a lot of oil! When u take off the stock cover the difference is wild. Overall an easy install. I do not have a lift or mods and so the track bar was in the way of the full plug. I only realized this after install. So yes I filled it through a syringe through the full level port. It worked though. Highly recommend this product

2008 Wrangler - GPappy
Great Protection for your Axle
My neighbor purchased these for his JK and had me install them. The fit was spot on and the installation was straightforward. I am not a professional welder but I had no problem welding these up although he was already planning on replacing the ball joints so I did not have to worry about cooking those. He also had the axle out of the Jeep so it only took a couple of hours start to finish. Liked them so much I am going to buy a set for my JKU which I just put bigger tires on.

2004 Rubicon - Stovebolt
Axle Replacement
Had to replace the OEM on my 2004 TJ Rubicon. Quick shipping but I ordered the wrong part. Yes, it will fit a TJ but not a Rubicon with a Dana 44.

Review shared from G2 Axle and Gear 30-Spline Dana 44 Axle Shaft; Driver Side (97-06 Jeep Wrangler TJ, Excluding Rubicon)
2006 Wrangler Unlimited - AVail
Great replacement axle shaft
Great replacement axle shaft. Please note that you will need 1/2-20 2" screw in axle studs for a TJ/LJ. Took less than an hour to replace even with putting on a new brake caliper and pressing on the bearing and collar. This axle shaft is way better quality than OEM.
