Differential Cover Dana M275 10.8″ 14 Bolts Rear Axle For 2017+ Ford F250 F350 Super Duty | SPELAB
What is the one part that takes abuse off-road first? Differential covers are on the axle lower to the ground. Factory diff covers are usually thin and unable to withstand much abuse. Failures occur from punctures and “peeling up” the edge of the cover. Spelab offers a Heavy Duty Diff Cover for the Ford M275 Super Duty 14 Bolt Rear axle on year models 2017+.
Function:
Protects the differential, seals the differential, stores differential fluid.
Fitment:
2017,2018,2019,2020,2021,2022,2023,2024,2025 Ford F250/ F350 Super Duty SRW
Note: The year and model may not guarantee compatibility. Please confirm whether the axle is DANA M275 10.8″ 14 Bolts.
Innovative points:
1. The external heat sink design increases the contact area between the differential cover and the surrounding air, enhancing heat dissipation performance.
2. The internal diversion groove design aligns with the direction of liquid flow in the differential gear's rotation, ensuring maximum flow rate for better lubrication.
3. The use of aluminum alloy material significantly improves cooling performance compared to the commonly used iron material. When comparing billet to cast products, billet items are often considered more durable and built for long-lasting performance.
4. An external observation mirror with a floating ball is used to monitor the oil level. Traditional observation mirrors in the market may darken over time, reducing visibility. Therefore, the floating ball allows us to monitor the oil level even if the mirror darkens.
5. The outside with black wrinkle paint providing rust resistance.

Let customers speak for us
I was impressed with the build quality. And very happy with the cover features: fill plug, drain plug, sight glass, nice paint, cooling fins and machined channels on the inside to direct fluid flow. I also put in some AMSOIL diff fluid. A winning combo. Love that gasket and premium hardware is included. A much better deal than the Banks cover. This cover will cool plenty abd direct fluids where it needs to go. I’m happy with my investment and highly recommend.
Fairly straight forward to install. My truck seems to be running and breathing a ton better.
Installed this billet version onto my 2019 Roush F150 recently. I wanted a cover that had the proper fluid flow vaning and fill and drain plugs to make future fluid changes easier, as I plan to renew the fluid every 30k miles. The sight glass so you can see the level and the condition of the fluid is also a great feature. I did quite a bit of research on which cover I wanted to install and saw the fluid flow issues with the square back covers, whereas this one has the proper curved design and vanes in it to direct the fluid that's coming over the top to the correct places of the differential for proper lubrication. I went with the billet one so that it's stronger than the lower priced cast version, as I keep my vehicles forever (20 years and 200k miles or more) and would rather do it right one time than have to do it again. The magnetic plugs to capture any ferrous gear wear is also a nice benefit. Installed with LubeLocker gasket.
Fit like crap. As did the down pipe. I got ppe ones and no refund from spelab
Fits very well and is really well constructed. Also looks really good installed in the truck!
Fit, "Like a glove!"
Didn’t have an issue with the install. Instructions weren’t real clear but overall the install was easy. Parts seemed to be good quality.
Fit nice and looks great!
I love it wish I had a tuner for my truck now, but I love it thank you
Perfect fit! I love your products!
I love this intake manifold and heater delete all in one kit, I would put one on every cummins. I got the horn style without the EGR parts and it puts me at ease knowing I'm not going to be getting vaccum leaks at all the block off plates and have to deal with that pesky butterfly valve. This kit really woke up my truck, I wasn't expecting a whole lot of gains but they are definitely there. I run an aftermarket turbo setup, bigger injectors, fully deleted, straight piped (4" but want the 5"), custom tuned, cold air and manual swapped, so like I said I didn't feel it would make a difference but I felt the difference. Love this companies products and am looking to go with there sick valve cover and maybe there 5" exhaust before long.
Great price and works amazing. For the price I thought it would be cheap but it's not its great quality perfect fitment and looks amazing id recommend to anyone thinking about getting rid of the stock one. Worth every dollar
Comes with everything needed. I bought the intake so there was no need for some of this kit so if your buying a intake as well save some money and get the one without the valve delete. Quality parts id buy it again
Worked out amazing with great fitment. With the stock 4 inch downpipe this makes it a complete 4 inch straught exhaust so saves money from having to buy a full 4 inch and sounds the same and ships alot faster
very awesome good fit easy install
