Aftermarket Diff. Cover or not?

I keep hearing tons of negative info on clearance issues with new differential covers such as riddler, etc.

I have a 2005 Wrangler Se, 2" Lift,anyone have picture of what cover they use and does it clear everything?
Also is there a good way to measure the clearance I have now?

x2 That's a good question! I'd like to put some diff covers on but don't want to hit the track bar in the front. I like the ARB covers because they have drain and fill plugs, but I've read that the front cover of this brand will make contact with the differential.

I'd like a more protection and the option of of a drain plug so the cover didn't have to be removed when changing the gear oil. Some have recommended the use of skid plates for the differentials instead of heavy duty covers.

They usually only hit if your running ALOT of lift, in excess of 6 inches I would say. I am runing about 4 inches up front and I have no issues :

Are you still running your stock track bar? because most of the complaints I hear are when people are running an aftermarket diff cover and track bar and the track bar doesnt clear because it doesnt bend around the diff as much as stock. Jks is the one i hear most complaining about.

I have the stock trac bar for now. You can get interference with gas tank on rear diff/diff cover very easy with more lift. this is why alot of people tummy tuck to raise the tank up and away from the rear axle. the front diff can hit the track bar but I am not as educated on that. usually its on higher lifts and the bigger covers. my PS was only about an inch and a half deeper than stock.

The stock cover is the best option. Trust me on this one.

If you want to beef the diff up a bit, use a bolt on skid like Warn or Rugged Ridge...or buy a Barnett skid.

I too like the stock diff cover. If you bend it, pull it off and hammer it back. If you really bent it, go to a pick and pull.

Or you could add a half diff cover.

Yep, great plan. What happens though if you smash it into the ring gear?

The issue is when a person increases suspension lift and the rear axle gets pushed back for centering rear wheelwell the Trackbar is mounted via frame on passenger side and rear axle on drivers side. I had to remove my rear Trackbar relocate for awhile to raise up my rear Trackbar on the passenger side.
I believe if you get a relocate via axle housing it lifts the Trackbar upwards to level it and not downwards

If you like to use your jeep in the rocks, you will eventually hit the bottom edge of the housing/cover and it will start leaking. When you take the rear cover off to fix the leak, you will see the diff housing is peeling metal back into the gasket area, which needs to be ground off before you bolt the cover back on.
Running a good aftermarket cover, like a poison spyder, $130,riddler, $110, blue torch fab, $150, or the expensive ARB, $187, will stop this and you wont need hammers or trail repairs like we've seen over and over with the stock ones. I've seen damage on the trail range from a slight leak, to removing the stock cover to beat it flat again.

So what do you reccomend with my 2" Bds coil lift? I do plan to go to 4" eventually so I want one that will work then too.

The guard shown above in post #12 is a good choice. It hugs the OE diff cover and doesn't normally cause any interference problems problem. Warn makes one just like it which is available at http://www.warn.com/truck/mounting-s...al_plate.shtml

The below from Currie is a design I like. They take a stock cover and weld a ramped double-wall to the lower half of the cover. The benefit to this design is that while it beefs up the lower half to resist damage, it leaves the upper half stock so it clears front suspension components.



You can find it at http://www.currieenterprises.com/ces...ie/JS-HD30.jpg for the front Dana 30 and and Dana 44 as well. I had one just like Currie's on my previous TJ from T&J but it doesn't appear T&J still makes or sells it.

Still haven't had any issues with my PSC and I have used it quite a lot. It sits nearly as tight as the stock cover.

you can always drill and tap the stock cover and add fill and drain plugs and have the best of both worlds

There is more to adding a drain plug to the stock cover than just drilling and tapping it since the metal isn't thick enough as is to tap.

If I were in the market for an aftermarket diff cover, I'd go with a welded plate steel cover over a fancy cast iron cover. You're going to have to try really hard to crack these guys or even bend them.

3/8" thick from RoughStuff


1/4" steel plate from UCF

well your right about the tapping .
I drilled and welded a shallow nut to the cover.
But it helps that I work at cater Aerospace and we are in the business of making experimental parts all day...lol

but it really is pretty darn easy

Those are ungodly massive. If your cracking cast iron covers you need to stop driving like a bulldozer. My 8.8 SOLID diff cover has more clearance than the stock cover and only cost 60$.

How is clearance on that UCF cover?

You'd have to call and ask them. If you call them, ask them how deep it is and they may even be able to tell you how deep it is compared to stock.

The reason I'd prefer a plate steel over a cast iron cover is that it doesn't have to be as thick to offer the same protection. Cast iron will crack before it bends. I myself don't run an aftermarket cover yet. Many more mods are in line before I get to that point. In the mean time I just put my tires on the biggest rocks in my way and try to keep my diffs out of harms way.

the ones that are basically the same mold as Solid, Rockcrusher, Rancho, Dynatrac, and a couple others? try looking at reviews of those...same thing.

In front, I run what used to be a Solid. Even with a custom high clearance track bar, I had to cut half the front face off and weld it closed to clear.
