Differential covers?

Has anyone ruined a differential rock crawling with the stock covers? I just wonder if this is a gimmick since the bottom of the differential is most likely to make contact. I can understand a skid plate but I wonder if a cover is necessary.

if you rock crawl at all, i'd suggest upgrading your diff covers.. they will peel away, crush in, and/dor damage your ring and pinion and/or lockers. They are worth the investment. Poison Spyder makes a quality cover for around $100. The ARB's are nice too but around $200 each.

Yup, peeled the rear cover back a bit to allow a bit of dripping. Replaced with some Ballistic covers since I know the guy who designed them.

It all depends on your type of wheeling. If you are running fire roads all the time...no need to upgrade covers. However, if you spend time on the rocks where there are bound to be bumps, scrapes, bangs, etc...its a wise investment. I have a TJ, but the rules still apply. I found for me personally, a front cover was not as important as a rear. I dont mash the pedal and plow through rocks to get over them...but the rear is a different story. I drag my diff over everything. If my rear diff is hanging me up, I WILL use the gas pedal a little bit to just get some momentum and drag over. This left me with the factory diff cover peeled back and weeping on a frequent basis. After market covers definitely stop the leaking since the material is much thicker.

IMO, unless there is a specific style/look that you HAVE to have...just buy cheap. SOLID makes one of the cheapest aftermarket covers out there, and it holds up great. I understand if you like the way a cover looks...but if you are just looking for protection, it can be had for pretty cheap. If you are looking for the absolute strongest, your best bet is probably with a welded cover such as Ballistic or ruffstuff...but in some cases the clearance for these isnt as good.

If you are not lifted, you can't use aftermarket diff covers. You could use a diff skid or guard if you are not lifted.

I've been trying to decide if i want to go with a beefy cover or an actual skid for my front diff.. the rear is going to be getting the skid with the CV protection.. I haven't hit anything yet, but the trails we run are very rocky and i would like to get off the beaten path a little more and not worry about them..

I don't get the point of shooting handguns and rifles at a differential cover. Seems that Spike TV and Four Wheeler magazine have joined in pointless 'infotainment'.

How about a real world test?

To answer the original question, I have seen several factory covers bent out or dented in. There is not much space between the cover and ring gear and even though they dont crumple like aluminum foil a decent hit can make them rub. I always recommend doing something better then stock with the dif covers unless just mallcrawling. No more then it cost it is worth it my book, and just like every thing else it boils down to what you budget for them and how much protection you want/think you need.

I vote for Poison Spyder. They are actually pretty inexpensive which is extremely surprising to me. They are strong, customizable, and they include everything you need to install except a torque wrench. For some reason I still don't have a picture of them installed.

I love how those look. Did you paint them to look like that or is that an option?

First time I've seen someone on the forum use the word Ballistic. I was going to ask if anyone's used them. I bought a battery mount from them to fit in the back of my hot rod and I am happy with them.

Solid has a great diff cover. They come with everything plus they are already powder coated. You can get 2 for he price some companies charge for one.

I second the durability of the "Solid" diff covers as you can see this one on the front of my jeep has taken a beating. This jeep lives on the rocks in south California's Mojave desert. It's to the point where I find myself only wheelin places like Stoddard Wells and the Hammers in Johnson Valley...home of the King Of the Hammers race. The cover was $71 delivered. Hope this helps in your discussion.

Solid.

I have seen a Solid 60 cover on a 700HP bouncer impact an immovable rock wide open and not even take a scratch.

plus they are cheap! I paid $65 each for my 60 and 14 bolt covers.

AEV, might be a tad overpriced but beefy and for me the inspection hole make it worth the money. I can checkout the condition of my gears without popping the cover off or draining the oil.

Not just Rock crawling can mess up the front cover...... If you like to run roads covered in Snow , ramming into a rock or a chunk of fire wood frozen to the road under the snow is pretty common around here....

Question, when installing the AEV diff covers, I thought I go for Lubelocker gaskets, or do you have any better recommendation? .... and what are the best fluids to use front and rear?
Thank you!!!

You can get a diff cover without lift.
