    not fit 1999-2004 IRS Cobra or 2012 Laguna Seca edition BOSS Mustangs or 2013-2014 GT500. Please note that this differential cover will

    not fit gears higher than 4.10, it will only fit gears 4.10 and below.

        5 Top Rated Questions

        In need of a new diff cover and gasket. How do I know this will fit my diff? Or how can I measure my diff to get the correct cover?

        • If you purchased your Mustang from the factory, you may follow the "Will it fit my Mustang" section on the product page for this Scott Drake Differential Cover. The 7.5" and 8.8" rears have different covers and gaskets, so you may compare the cover and or gaskets to one of a 7.5" or 8.8". Alternatively, you could always measure the size of the ring gear, but this would require digging into the carrier.

        "in the box" doesn't mention drain bolt or fill bolt like the Steeda does. Are those included? Also, my owners manual says factory fill is 2 qts, you say I will need 3 qts, why the increase?

        • This holds more oil so it will be requiring the 3 quarts. The only hardware this Scott Drake Differential Cover will be the fastening hardware as seen in the product pictures.

            Scott Drake dif cover is a win!

            Install was a breeze, looks great and holds extra oil to help keep the differential cool. The bearing cap preload set screws help ensure that the differential doesn’t walk around under load. Great price and will definitely inspire some confidence under hard launches! Thanks AM.

            Nice Cover

            I mostly drag race my '06 GT and needed to update the clutch pack in the differential. I'm running in the 11's now with Roush supercharger at 8 pounds of boost. Decided at my power levels a nice solid cover with convenient drain plug was a good upgrade. Well made, fits perfect.

            rear end cover by drake.

            Recieved cover, box was damaged but all parts were still intact. Installed with rearend still in car. I had removed swaybar so it was easier to install. I used permetix rear end gasket maker because it is friction modifier safe. I put teflon tape on main bearing bolts and added more to fill and drain plugs. I also added lock washers to all reareand bolts. Cover fit well and have no leaks. Looks great under the car

            I had it out on when I put larger gears in, leaks really badly the mechanic tried to fix it but we can't get it to completely stop, my advice would to be to find a better one

            Make it easy

            Knowing that the bolts are too long with these, I would advise that it is best to put these covers on with studs. Lock-tight the studs then use lock nuts, the crush type for the best lock down. This is far better than bolts. Also studs nearly always are strong and less likily to work lose.

            having a drain plug is an added bonus to the looks and strength

            After reading the reviews I decided to buy this differential cover to replace the factory one, and before installing I made sure to shave some of the threads off the ends of the supplied bolts to make sure it would seal properly. I don't really notice much difference when I put the foot down, but I believe that the main purpose of the units is to keep the rear end from blowing up.

            Great fitment, buy extra gear oil

            Just installed this today. Fitment is perfect, and even fit better than stock cover with aftermarket sway bar. My only gripe is that this cover requires a bit more gear oil. I dumped 3 quarts in there along with the friction modifier, but its still not full (this is on an 1988 with 3.55 gears). Buy an extra quart just in case.

            Nice part but hardware is junk!

            Cover is very nice and sturdy but bolts that it come with are cheap looking and drain and fill plugs have magnets in them which is nice but not when they leak. The plugs are drilled and then a magnet pressed into it but they drilled too deep causing the oil to leak thru the drain plug. This is very upsetting considering the royal purple 75w-90 is not cheap at all. So before you fill the rear end up full of liquid hold buy you some drain plugs that seal and don't leak

            Extra support

            No real performance gain... just peace of mind since , I now run 325/50/15 drag radials on my foxbody... Knowing i have a bit more rear end support makes me feel safer launching. A must have if your doing hard launches from a standpoint., Rear diff cap failure is common, this is a cheap way to help staying away from a expensive rebuild. Easy to install for the common guy...takes less than a hour, top it off with a good fluid and be on your way. P.S remember not to over tighten the cap braces...lite pressure is needed.
