Description
Lighter and Stronger. When upgrading the rear gears in your SVT Cobra it's a good idea to replace that wimpy stock Girdle Support System (a.k.a. differential cover) with a super strong, light weight Aluminum Differential Cover for additional safety and peace of mind.

Ford Racing Quaility. Add performance parts to your Pony made by the people who know it best. This Ford Racing 8.8" Rear End Differential Cover is cast from lightweight aluminum for strength and features convenient fill and drain plugs. The load bolts provide additional support for the differential bearing caps to increase ring and pinion gear life.

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 IRS Rear End Differential Girdle Cover is designed to fit the 1999 to 2004 SVT Cobras equipped with the 8.8" Independent Rear Suspension (IRS) rear end. not for use on non-IRS Mustangs.

  • No, the top hole is for a diff cooling system, the middle one is the fill hole and the bottom is the drain hole. On the inside of the cover they have a place marked on it where you can tap and drill your own temp sensor hole

    Ford Racing 8.8 03 Cobra Diff Cover

    I recently purchased this newly designed diff cover for my 03 cobra to replace the stocker along with my added billet flow irs brace. This is truly a very nice piece and the fit is perfect. In fact, this is what ford should have designed and installed on the car 9 years ago! The installation took about 5-6 hours on the irs because you have to tilt the sub-frame out of the car to remove the pumpkin to put the new cover on (you can not install in place). I used a lube locker gasket and some nice RP synthetic gear oil to put it all back together. All and All I highly recommend this cover for all cobra owners even though the work required to install is high.

    Should have come from the factory like this

    IRS brace or a beefier cover (such as this one) is absolutely necessary for the IRS cobras as the weak stock unit has a tendancy to break open during the jerky motion of wheel hop. The drain plug and cooler plug is an added bonus. Be ready to spend some time with this install. At least one full day of work if you've never disassembled the IRS before. My only complaint is that the machined mating surface had suffered some damage in transit. Could have been packaged better.

    Diff cover swap

    My cobra was leaking differential fluid so I put a Billetflow irs brace on it and it continued to leak so I put the ford racing cover on and it hasn't dripped since. Amazing product

    ford racing differential cover

    You can see the quality difference from the stock cover just by looking at it, I feel great about upgrading to this cover. The cover even comes with the longer bolts you'll need since this one is so much thicker than the original. It was an easy install but we had the differential out of the car I would imagine it would be a little more difficult getting the thicker cover in and out if we tried to do it with the differential still on the car, but aside from that it's a great product and I'm extremely pleased with it.

    Much stronger than stock

    This differential cover is much thicker and stronger than the weak stock cover. This product has gave me peace of mind that I won't break a cover during hard launches.
