So I had a bad axle seal so I figured while I have the old cover off to drain the oil I'll put a new diff cover on. Ended up having both seals changed and the right bearings changed as well.

I bought my Mag-Hytec Rear Differential Cover from truckcustomizers for $247
Mine is the 12 bolt 9.75 for the 2001 F150 4x4 5.4L

Looks much better! I plan on the same when I change my gears out

How many quarts you put in? I've read 6 should do it

 

Mag-Hytec claims 5 quarts. I got 4.5 in.

 

nice

 

Man that cover is as much as the gear set. What makes it so expensive and better. More capacity and cooling fins?

 

According to Mag-Hytec it holds up to 5 quarts of oil, and cools up to 40*C cooler.

 

Ill have one with my gear swap

 

Is there away you can put a temp sender unit in the new cover?

 

And it's got a magnet inside to collect any metal shavings over time. I got mine not too long ago.

 

Your stock one does to.
It's in the plug.

 

The Mag-Hytec is also alot stronger than the OEM paper cover is. Very good for off road situations.

 

Nice addition!

 

The fill hole is also a dipstick and the cover's 100x heavier than oem. Only bad thing about it is it's just one more thing to clean.

Looks good

 

I am not sure.



Thanks everyone!

 

Yes...these covers have ports for temp sensors. Cover is very well worth the money! Clean your axle and surrounding area and it'll make it even better...or worse depending on your outlook..LOL
