        Does it come with a axle vent plug? or does it use the stock axle vent as well.

            Nice Upgrade

            Had a leaky diff cover and decided to upgrade. Glad I did. Quality ford product. Functional, looks great. Came with the longer bolts needed due to the thickness of the cover. Make sure to pickup a gasket or silicone gasket maker.

            Excellent part....excellent service !!

            My Son told me about American Muscle, and swears by them for his '92 GT resto-mod project. I pulled the trigger on this sweet diff. Cover as a Christmas present 2 days ago. The price was lower than everyone else, and the part shipped within 8 hours of my order. These folks are fast, honest, and smart. They verified my fitment before charging me which nobody else has ever done for me. Well done AM ! You've earned a customer for life. Thank you, GR.

            Quick upgrade

            Talk about quick, if you don’t count the cobra differential clutch upgrade and cobra brakes install this cover only took maybe an hour to install the longest part being lifting the car and draining it. Even filling it up was a breeze with amsoil’s new flex pack gear oil left no mess and no waste.

            Nice piece of equipment. Has the look of a upgraded stock replacement. Great for fluid change. Added this piece when changing the rear gear and pinion. Definitely will make changing the break in fluid

            Much nicer than stock

            Looks way better than the stock cover, and should keep the fluid cooler. This cover does come with new bolts and drain a fill plugs which will make future maintenance much easier.

            Big differance

            I enter my car in shows, look wise it is great, and using the old touch test it is cooler, so therefore has to be doing something good. Install was simple however you must remove the panrod bar. Just remember once you remove the pan-rod bar bolts, the only way you are getting that bar out is to lower the car back to the ground, it will come right out. Jack it back up and put the cover on, lower it and install the bar. I have a lift so it was not all that bad

            Easier to change fluid

            This diff cover certainly looks better, and does keep the fluid cooler, and absolutely makes fluid changes much much easier. However, at a road-course HPDE in a car with only partial bolt-ons I am still heating the diff fluid enough to spit out of the overflow valve, so the cooling power isnt exactly mind blowing, but seemingly enough to keep the diff from cooking completely, so money well spent.

            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.

            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.

            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.
