  Overall an excellent product that adds strength and makes future diff oil changes a breeze.

  I was very impressed by this cover right out of the box. The fit and finish are excellent. A very well crafted and solid part. The hardware included were also top notch. I've heard that some of the other differential covers on the market come with very weak bolts that tend to break before the proper torque values are reached. I had no problem at all tightening the supplied bolts to the proper torque setting. One of the nicest things about the Ford Racing cover is that you don't have to relocate your panhard bar for installation like you do with many of the other covers on the market. This cover fits perfectly with absolutely no modifications to your suspension. You do have to remove the panhard bar temporarily during install to make room so you can tighten and torque the bearing preload bolts. The instructions were also pretty good. However I was surprised that the instructions didn't say to put any kind of sealant on the fill and drain bolt. Being over cautious, I put thread sealant on the fill, drain and preload bolts to prevent future leaks. The instructions also didn't include torque values for the fill and drain bolt. I contacted American Muscle about this and was told to just snug the bolts up pretty good being careful not to strip the threads. I did, and haven't had any problems so far. As far as actual performance, you probably will not notice any increase in performance with this part. You will in fact have piece of mind that your differential is a lot stronger with this cover and that your next fluid change will be as simple as loosening two bolts. Overall an excellent product. Perfect fit. Easy install. All at a great price from AM.

  Rugged, and good looking too

  My stock differential cover was leaking, so I had the choice to either buy a new one or re-seal the current one. I chose to upgrade to this one, and even though I don't have a lot of mods or upgrades done yet, it's still nice to know I'll never need to replace this cover. Plus, it looks really great on the car. most people won't see it, but with Ford Racing on it, it looks like it belongs on the car anyway. It also came with instructions, and what amount to torque the bolts at so you don't over tighten.

  Great piece

  I had this installed at the same time as changing out the bearings in the rear diff so I cannot comment on the install but, the fit and finish are next to perfect. I have the BMR panhard bar which clears this cover without any issues. Mine came with polished stainless bolts and a rubberized gasket. The unit itself comes as a bare cast aluminum, so I opted to put on a couple coats of high temp clear coat engine enamel to keep it looking its best. Also I would recommend putting Teflon tape on the fill, drain and load bolts to prevent leaking from those areas. You don't necessarily notice a difference with the load bolts or the beefier construction for that matter but, but the peace of mind knowing that its is 100x stronger structurally is worth it in itself.

  Ford Racing Diff Cover

  Very pleased with the diff cover. Makes me smile every time I jack the rear of the car. Its a mod that you know is there but not everyone notices. Definitely makes changing the diff fluid easier and it gets all the fluid in the pan versus trying to pry off the stock cover and hoping everything makes it in the pan. To install you need to remove one end of the panhard bar. I made the mistake of removing the old diff cover and fluid, but realizing I didn't have the right tools to remove the panhard bar so I had to put the stock diff cover back on and fill it with new fluid. The new cover wont fit since the space between the rear axle and panhard bar is too close for the new cover and you wont be able to tighten the two bearing support nuts in the middle of the cover. Had the dealer install it while they were working on my car for no charge. Ditch the paper gasket for rtv gasket stuff if you dont want the cover to leak. Overall very pleased!

  Rock Solid Diff Cover

  I am running Ford Racing 4.10 gears and a Ford Racing Traction - Lok Limited Slip Differential with Carbon Discs and this cover was the perfect choice to finish the build. You can't go wrong with Ford Racing. Don't let the price shy you away. If you invest in new gears this cover will surely protect your investment. I am running a Beefy Whiteline Adjustable Panhard Bar and Brace and the low profile design of this cover allowed for a perfect fit with no clearance issues. It gets a 5 for Performance Gain because it is extremely well made, tightens up the rear real nice, and provides heat dissipation to extend the life of your gears. My mechanic smiled and said I made a GREAT choice when he saw it. Go for it! You will be happy you did. Thanks AM for Great products, Top notch Customer Service and Free shipping. You Guys Rock!

  Great product, hopefully it will not oxidize. Easy to install and gives you a rear facing fill and drain plugs.

  Arrived on time and item was just as described. Looking forward to putting it on car looks great and feels like a very high quality part. Would have give a higher rating but must put on car in order to do so.

  Great Looking

  This cover looks awesome on my Mustang, if only you could get low enough to look under my car. It was extremely easy to install. The instructions were very precise and easy to follow. I would suggest replacing your axle seals when installing the cover, mine was seeping. I replaced my axle bearing/seals and cover in under 4 hrs.

  Ford Racing Differential Cover

  Looks and feels substantially better built than the OEM cover that rotted away and started leaking after 75,000 miles. Can't really give much of a review as it has only been installed for one day other than to say that it looks good.

  Great addition

  Straight forward install. The cover is well built, thick, and cleared my stock sway bare with ease. Even though its not visible the added insurance its there is enough for me. I thought long a hard about other variations of Diff covers, this one was the best choice for me. Great shipping times and Customer Service.

  Nice way to dress up your rear

  After replacing my diff and gears I decided to update the cover as well. Nicer styling than factory and completes a show car looks as well.

  Fun with the cover!

  I bought this to replace the factory cover that had been hit by track debris. First let me say my car has a panhard bar and an large sway bar installed. I also do all my work on jack stands with out a lift. I was able to remove the old one without drama, but in order to install this cover I had to remove the panhard bar and sway bar. Then drop the axle down some in order to gain clearence to install the cover and it's bolts. If you where doing this on an unmodified Mustang I would say 2 hrs install time, but if you have all the stuff I have under mine plan on a half a day. Also refilling the diff was much easier through the cover opening rather than from the factory fill opening. One note of caution on here it says you need 3 quarts of oil, but you won't need a full 3 quarts. You'll over fill the diff. Check it using the factory fill hole. It looks great and I'll post a picture later to add to all the others here.

  Good deal

  Makes oil changes a snap. I track my car so this is important also looks good to bad I can only see it from under the car. It also allows you to ad more oil if you chose a gear lock diff.

  Looks Great!

  This cover is a nice finishing touch to the rest of my suspension mods and 4.10s. There's no noticeable performance gain, but I'm sure things will last longer back there. Fluid changes will also be easier as well.

  Looks great

  Took the stock cover off and put this one one. Directions are very easy to follow. Love the fact that it has the drain and fill lines built in. The only negative is that the gasket that came with it was slightly torn but was on the very outside so it did not affect performance.
