Differential covers

[USAF-FD-NJ]

So I've been mulling the idea of get performance differential covers (Maghytec, AGE, etc.). Any input and what would be the correct and best fluid?

I have a true 350 everything stock and bought the truck 3 years ago with never doing a change.

I would just get an '08 SD rear cover with new bolts (a lot cheaper than MagHytec), although I don't thiink there's a similar one for the front diff (others please chime in here if there is). I use RedLine synthetic 75W-140 since I tow with my truck. Cheers!

Mag Hytec or AFE are both nice covers. I would suggest Royal Purple Synthetic 75-140 Gear Max Fluid.

I agree with Patrick

$45 and some new grade 8 hardware

The '08 cover looks cool but as I always say if I want a new truck I'm not going to buy stock parts for a new truck and put them on my beat truck. Very good insight. Does Lucas Oil make gear oil?

That why you go with the FORD aluminum cover for $45 and put the saved money somewhere else

they look great painted and fins sanded or polished

I couldn't see spending more either

Honestly i laugh at guys who have $500+ worth of diff covers on their trucks for no real reason. Get the SD cover, paint it or polish it to your desire, and buy the best gear oil you can find. Then spend that extra $$$ somewhere that will actually give you results.

BTW, my Ford deal only wants like $60 for a diff cover. $10 at most for new SS hardware and your set.



Now if your running big HP and putting the truck under constant heavy loads, and verified that your diff is getting hot, then maybe an aftermarket cover would be something to look into.
