How do I pick a differential cover?
1. Key factors in selecting differential covers
Compatibility
- Confirm the axle model: Choose a compatible differential cover according to the differential and axle type of your vehicle (such as Dana, AAM, Ford, GM, etc.). For example, axle models such as Dana 44, Ford 9.75" or GM 8.5".
- Front and rear axle differences: The front and rear axle differential covers are usually different, and need to be confirmed according to the specific axle.
- Number of bolts: Check the number of bolts on your differential cover (such as 10, 12 or 14 bolts) to ensure that it matches the selected cover.
2. Material
- Cast Aluminum
- Cast Iron
- Steel
- Composite Materials
3. Usage
- Daily driving: The original differential cover is usually sufficient, and you can choose an OEM or original differential cover.
- Off-road driving: You need to choose a reinforced differential cover, such as a thick cast iron or aluminum differential cover, to increase impact resistance.
- Towing and heavy loads: It is recommended to choose an aluminum differential cover with good heat dissipation and high strength to avoid differential damage caused by overheating.
4. Heat dissipation function
Some high-end differential covers are equipped with cooling fins to improve heat dissipation efficiency, suitable for heavy loads or long-term driving.
5. Oil capacity
- Increasing the capacity of the differential oil can help reduce oil temperature and reduce internal wear of the differential.
- Some differential cover designs can increase the oil capacity (Extended Capacity) for high-performance purposes.
6. Brand and quality
- Premium brands usually provide higher manufacturing precision and durability, such as SPELAB.
- Make sure the selected differential cover is quality tested and performance verified.
7. Additional features
- Magnetic drain bolt: Helps remove metal debris and protects the inside of the differential.
- Sight glass or dipstick: Convenient to check the oil level.
- Reinforced structure: Ribbed structures or thick-walled designs provide additional protection.

Let customers speak for us
from 2455 reviews
Intake horn is real nice, block off plate is real nice, gaskets are decent. I removed first 3 fuel lines and the cp3 line and had mine done in about 4hr by myself start to finish. 2012 Cummins. No cel, no issues. Took away a lot of the black smoking. Increased boost noticeably. Five stars.

Good fit, sounds awesome, definitely made a difference, hose clamps could be a little better, holes was off a little for the sensors, but for the price overall good product!

They have great customer service what I order was much better than what I was expecting to receive thank you for guys for everything

This was a very easy install, the parts seems to be good quality.

Great products, the updates and revisions to there parts show they care about making things better. 100% would buy all my parts from Spelab.

Directions were not good and there isn’t a heater bolt yet..but the product is great and you can’t beat the price. Happy with the product.

This is a good upgrade. I change the rear differential fluid frequently so now I will be able to drain and refill more easily. Easy install. No leaking. Hardware and gasket included. Very happy

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!
