Description
Stronger Than Stock. When upgrading the rear gears in your Mustang it's a good idea to replace the wimpy stock differential cover with a super strong, light weight Aluminum Differential Cover for additional safety and peace of mind. This low profile Ford Racing Differential Cover features load bolts to provide additional support for differential bearing caps to prevent side-to-side deflection.

Cast Aluminum; Reduces Heat. Constructed from light-weight 356T6 cast aluminum the Ford Racing Mustang 8.8" Differential Cover dissipates heat much faster than the stock factory unit to prolong the life of your ring and pinion gears.

Recommended Upgrade. When changing your differential cover it is recommended to upgrade to fresh Royal Purple Synthetic Gear Oil. You will need 3 quarts of Gear Oil.

Application. This Ford Racing Differential Cover is designed to fit the 1986-2012 Mustangs equipped with the 8.8" rear end, including the 2011-2014 V6, 1986-2014 GT, Bullitt, Mach 1, and 2007-2012 Shelby GT500 and 1993-1998 SVT Cobra. It will not fit 1999-2004 Independent Rear Suspension (IRS) equipped SVT Cobras. Will not fit 2013-2014 GT500.

Will this clear Steeda panhard bar? Will this clear Steeda's adjustable street panhard bar? (Steeda part # 555-2551) Or, does anyone know the dimensions of this diff cover? Knowing that, I could go measure for clearance.

    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.

    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.

    amazing

    well as i build my stang up.. i just rebuilt my 8.8 with full 31 spline setup with 4.10's and installed this cover, it feels stout and way more supportive then the stock flimsy like aluminum piece.

    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!

    great product

    Install was a little odd. Bolts are hex for the cover, and the sway bar was in the way for the bottom bolt (I have the eibach anti-roll kit) but I feel much more confident about my rear now. Not to mention it looks grreat.

    Interferes with panhard bar

    I drag race the car 40 weeks per year and installed the new diff cover to prevent deflection. Unfortunately, the diff cover hits the panhard bar while driving. AM said it would fit, but it doesn't. I had to order a BMR extension bracket for $79 more: http://www.americanmuscle.com/bmr-panhard-relocation-0512.html Bummer.
