Ford Performance Diff Cover

Has anyone installed or used the Ford Performance Differential Cover? I ordered one because I like the looks and my rear has some weeping anyway. I can’t seem to find any info on it.

What part number? Aluminum or carbon steel?

Part M-4033-F975 and it’s powder coated iron.

Ah. Cast iron. That sucker will rust. There are better aluminum options.

It is powder coated. I liked the looks of it that’s why I bought it. Also has the fill hole on it.

Love the fact that it has Drain Plugs.
Also, give me a Cast Iron cover over an Aluminum cover.
BTW... Engine Block, Head, Water Pump, these are all made from what again ?!!!!

Most blocks and heads are made of aluminum anymore. So....

Got the cover in today. It is beefy. Very high quality piece. Will be installing tomorrow. My son wants to help install so will knock it out when he gets home from school.

I have two of these made out of billet aluminum , stud girdle . Good luck finding one . I bought 2 back in the day, one for my lightning and one for my buddy , who wrecked his lightning a week later and never got to put it on. Ended up sitting on a shelf . Installed on my Raptor years later. These came out in 2003. Pretty sure they stopped making them. Pics are from google search. they were pricey too $600ish if i remember. They are a work of art.

Here is a pic of the diff cover.
