Simple bolt up to rear, I had dealership do it when they serviced the rear. Other wise can be installed by yourself with a socket and gear oil (dont forget the ford rear friction reducer!). It is setup ...

I have a Whiteline adjustable panhard bar on my 2009 GT. do I need a relocation bracket to clear the finned diff cover?

  • You will not need a relocation bracket for the Whiteline adjustable panhard bar to clear the finned diff cover.

Does this cover come complete with all the gasket that is required for installment? How much fluid do I need to refill the differential?

Trini

  • This cover does not come with the gasket and it will need 3 quarts of Royal Purple Synthetic gear oil.

    Nice track upgrade features

    Simple bolt up to rear, I had dealership do it when they serviced the rear. Other wise can be installed by yourself with a socket and gear oil (dont forget the ford rear friction reducer!). It is setup if doing track runs to upgrade to a rear differential cooler at a later time. I like it as holds more fluid then stock GT cover. Also has cooling fins so you know fluid will stay cooler to help rear end parts to have a longer life.

    Good for the money

    I was experiencing some high temps and accelerated wear in my factory rear end under occasional track conditions. This finned diff is exactly what should have always come standard on any of the GT and up mustang models, and seems to have helped keep the temps a bit more under control.

    Cools the Fluid and Looks Great

    I installed this Finned Rear Diff Cover, along with a New Diff. Installation went as smooth as silk. Everything I needed was in the box. Before I installed the Diff I did a temperature check. After installation there was a noticeable drop in the Syn Oil temperature. I would highly recommend this product.

    Great fit, quality product

    Purchased this as it was time to change the rear axle fluid on my 2008 Bullitt (60k miles, very dirty fluid). I figured I would change out the cover to make future changes easier, as the standard cover does not have a drain plug. The cover is made very well, and has magnetic bolts on the "fill" and "drain" plugs. They are not exactly meant for Fill and drain, I think they are more meant for the optional GT-500 diff cooler, but they could work as such. The supplied hardware fit perfect, and had some loctite reapplied. One note about the install, the panhard bar did have to be removed to fit the cover on. I would suggest taking out the panhard bar first thing, it will give you more room to work during the rest of the process. the stock panhard bar will fit back in place once the cover is on with plenty of room, but it had to be removed first. not a big deal as it takes very little time. All in all pleased, and if the fins do help cooling thats just an added bonus.

    Great Fix for axle leak

    Got this for my 2011 GT because I was having oil leak from the axle vent tube. I replaced the vent tube first with Ford OEM part and still had the drips on the garage floor. Installed this cover because it has the fins to keep it cooler and it worked. No more oil drips. FYI you will have to drop the panhard bar in order to install new one. And be sure to get the longer bolts that are suggested with this, stock bolts are too short. Great product, looks great, and it works for leaks.

    Ford Racing Finned Differential Cover

    Needed to change the differential oil so I thought I'd swap out the cover with this on. Well made and looks cool.

    This product is better than stock!!!

    It has the fittings to run a diff cooler. I will be installing it at a later date. I bought the entire 8.8 diff for my 07 GT. I LOVE THE WHOLE SET UP!!! For me it was like flipping a switch. Also the diff cover looks great.... Way better than stock!!!!

    A great finishing touch to any rear end rebuild!

    You can't go wrong with Ford Racing quality and fitment. This differential cover is a great looking and functional upgrade to add to a gear swap project. The finned design will help dissipate heat for better gear life and the fill/drain plugs will allow for easier gear oil changes in the future. If you're spending the time and money to swap your gears go ahead and swap out the stock diff cover too, it's worth it for the looks alone. I’m very happy that I picked one up when I went to 4.10 gears.
