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+ Ford F250 Super Duty SRW w/ HD Tow Package
2017+ Ford 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.
Specifications：
Q1: How to plug a tiny hole on my truck differential?
A1: To plug a tiny hole on your truck differential, clean the area thoroughly, apply a high-quality epoxy or JB Weld, and allow it to cure as per the manufacturer's instructions. For a more permanent solution, consider welding the hole shut.
Q2: Is it safe to work under a car on jack stands?
A2: Yes, it is safe to work under a car on jack stands if they are properly rated for your vehicle's weight and used on a flat, stable surface. Always use multiple jack stands and never rely solely on a hydraulic jack.
Q3: What causes the rear differential to leak?
A3: Rear differential leaks can be caused by worn seals, damaged gaskets, loose bolts, or cracks in the differential cover. Regular maintenance and inspection can help prevent leaks.
Q4: How tight should a pinion nut be?
A4: The pinion nut should be tightened to the manufacturer's specified torque, typically measured in foot-pounds (ft-lbs). Over-tightening or under-tightening can lead to differential damage or failure.
Q5: How to identify a Dana 70 rear axle?
A5: A Dana 70 rear axle can be identified by checking the axle's BOM (Bill of Materials) number, usually stamped on the axle tube. You can also measure the axle shaft diameter and count the number of bolts on the differential cover.
Q6: What happens if your rear differential goes out while driving?
A6: If your rear differential fails while driving, you may experience loss of power to the wheels, unusual noises, or complete immobilization of the vehicle. It is important to stop driving and have the differential inspected immediately.
Q7: How to take off a frozen filler plug on my truck differential?
A7: To remove a frozen filler plug, apply penetrating oil to the plug and let it sit for a few hours. Use a breaker bar or impact wrench for additional torque. Applying heat to the surrounding area can also help loosen the plug.
Q8: How difficult is it to replace the rear differential on a car?
A8: Replacing the rear differential can be challenging and requires mechanical expertise, proper tools, and a safe working environment. It involves removing the drive shaft, axle shafts, and differential housing. Professional assistance is recommended if you are not experienced.
Q9: Is it safe to jack a car up under the differential?
A9: Yes, it is generally safe to jack a car up under the differential, provided you use a proper floor jack and place it under the differential housing center. Always use jack stands to support the vehicle once it is lifted.
Q10: How to extend the lifespan of my differential?
A10: To extend the lifespan of your differential, regularly check and change the differential oil, inspect seals and gaskets for leaks, avoid overloading your vehicle, and ensure proper lubrication with a high-quality differential cover like the SPELAB POWER RAM-AIR differential cover.

It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore
Not to easy if you don’t know what your doing\not mechanically inclined, but definitely worth it for the quality love the stuff!
Glad your product is on the market. I love the looks of it and the performance aspect of the intake horn. Glad I chose ya’ll. Can definitely feel the truck breathing better!!!
Overall, great kit. Wish I would have ordered the can bus plugs at the same time. A few modifications were needed to make everything work but nothing too difficult if you can tackle this type of work to begin with.
Great quality and fit
Great product sounds amazing
With my old kit that kept leaking, an abnormal seal size and changed colors as the plastic got warm. I installed the Spelab kit and fits good and have the reassurance of the locking ring to keep it in.
Looks good and very good quality
