Aluminum Diff Covers

[Duro5341]

Hey Guys

I am looking into buying an aluminum diff cover for my 10 bolt rear-end

I am looking at this one in particular
http://mag-hytec.com/store/index.php...31efbaf03241bd

I like the idea that it holds 4 qts, rather than 1.5qts stock, and it has an o-ring for a gasket, so I don't have to fiddle around with silicone. It also has a drain plug, so changing the fluid will be easier

Now the stainless bolts they supply are allen key heads, and I live in Ontario, and drive year round. Do you think the salt will corrod the heads?, can I put a dab of Anti-sieze on the treads, so they don't sieze in the rear-end?

Has anyone purchased this one?, what was your experience with it?
Any, and all comments are welcome....

Thanks
Cameron

It's an awesome cover if you need it. It ain't cheap but what is on these trucks.

If the bolts are a high quality of stainless they won't rust and it never hurts to use anti sieze on any fastner that lives in a harsh enviorment.

I'd be worried about the cover corroding before the bolts especially the exposed parts of the fin's unless theres a clear coat on it.

As for the o-ring seal i don't think it would work on my rear end cuz te housing mount surface has a very rough cut finish from when it was machined and unless yours is really flat and smooth it may not seal so if i were you i'd remove the one on the truck and look at the housing mount surface before you order it.

$250 is just too much for me to justify spending on a rear end cover.

Something like that would actually be functional because the girdle helps strengthen the rear end. 8.5 10 bolts are decently strong though.

The housing mounting surface is very clean, and there are no nicks, or gouges in it. I had it removed last year, before I got the rear-end rebuilt.

So I think it'll seal just fine...but only time will tell I guess.

The whole cover does have a clearcoat finish, so it won't corrod

Thanks

I have 2--you can't go wrong IMO.

I have one on my Duramax. It is a very high quality piece, and no leaks.

On my truck, I used the cover that Currie sells and it had the stiffener bolts for the bearing caps.

This is a little different .... $59.95 + $12.00 ship.

Yea, the last one is just in time for the Halloween. For the practical bunch - myself included - last Saturday morning have replaced stock stamped steel cover on my 14 Bolt 10-1/2 rearend


with Mag Hytec cover. Mag's are not cheap, but the quality of the aluminium casting, powder coated finish and supplied hardware (the total package) appear to be the best available on the market. Once, installed it took 5 qts (1Gallon + a bit from another battle) of SAE-85 to full her up. Future service checks are now a breeze with built in oil level dip-stick.


Installation was rather trivial - except that brake line support brackets had to be modified. Thin one was trimmed with sheers and the thicker one was trimmed with a hack saw. Couple of passes with a flat file to keep all sharp edges at bay. About 15 minuted for mods.

How did you do the vent tube problem?

What I don't understand, is I am not raising the level past the factory fill plug on the side of the rear end. So yes there is more fluid, but it's not any higher than the fectory level. So this vent tube problem, shouldn't be one. Or the factory cover would be pissing oil out the vent aswell....or am I not understanding something here

Duro'

If you look at full res photos you'll find a 3/8" hose going from left side all the way across toward frame rails to the right. I know, it is tough to see it on the left side, but it is clearly visible on the right side of the photo - running parallel to the brake line. At one end it taps into dif housing above oil level. Breather end has special plastic valve-breather to keep external moisture from getting in. Since I am not original owner I do know when this mod was performed.

Not a good answer - aghh??

omg that is sexy... I want I want... pm me with where to get? lol

[BaddBusa2005]

i would much rather have the girdled cover.

As for the hex key bolt heads, stuff a little Vaseline into the hex holes. It'll repel moisture and is easy enough to get out for servicing.

Or go to a hydraulic hose manufacturer and get some of those little red plastic caps they cover the ends of the hoses with that'll fit over the bolt head entirely. Goop just a touch of silicone in the cap to help keep it on there.
