    You could also verify the fluid level at the OEM plug on the front of the differential cover. With your truck level check the height of the stock fill port to the ground (or smooth surface like a garage floor), then do the same with the B&M fill port. Maybe there is a discrepancy. I would fill using the OEM hole and verify the 2 holes are the same height. You would only need to do this once and note any difference for the next time you drain and fill using the B&M ports. You don't want to overfill.

I prefer functional parts with a lot of bang for my $$.
    Everything I get DOES have a better function except for a few that are for looks only. I'm just blessed to be financially set to have some better things in life than most. God, family first. I completly understand where your coming from and respect it.

    Well isn't that the coolest freakin diff cover!! Thanks for sharing the pic and I too have been blessed financially which means I'll probably "have to have" one of these bad boys! I'm not sure whether to thank you or not. LOL I spent the afternoon in "LA" Monday...I knew I was there as soon as it promptly began raining at 1 pm (in Mobile). Back in the day I lived there for about 7 years and I'm pretty sure it rained every day during the summer at 1pm.

    All I wanted was a diff cover with a drain plug, and not wanting to spend too much, so I ended up with a G2 cover. Only about 1/2 quart more capacity than stock, but fits my bill.Name:  IMG_20160720_175955.jpg

    I have mag hytec on mine. Great piece and looks the best out of any cover IMO.

    Those of you replacing fluid in your diff, it is simple, plug the fill plug on side of housing. Truck on level ground, when the fluid starting weeping out the hole as filling up, youre good. Same procedure on transfer case, except that has a drain and fill plug.

    Those questioning the cover, for most it is a waste of money. The benefit of it is built in drain plug for maintenance and if youre towing a lot or running larger tires/wheels or both. The extra capacity of fluid helps keep everything inside cooler simply due to having more fluid.

    The mag-hytec has a dip stick thats magnetic as well. The factory unit only the fill plug is magnetic. This helps pull the metal out of fluid a lot more vs stock.
