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.

Great quality part, and looks awesome!

Everything fit like a glove aside from hose. The 5/8” hose provided is not very long. Had to obtain from auto parts store to complete neatly. Also missing gasket for oil side of turbo. Had to obtain from dealership. Great product aside from these issues.

Great product. Good price for an aluminum cover with all the extras. Fill, drain and fluid level view window are great options. Top notch product.

05 LLY Duramax. I soaked bolts for days in a penetration oil, used heat and had a bolt break off in turbo, which made install miserable. I also did mine while transmission was out. This would not be easy with transmission attached, just a FYI. Great product, decent shipping, but not sure what the bolts that came with it are for, because they were not even close to stock up pipe bolts. Had to retain stock mounting hardware!!

Awesome people and products an I will be using yall on all my builds I got three more trucks to do maybe put some instructions in for none mechanical people would be very helpful I bin working on disel hevy equipment for over 30 years I know where everything gos an how it works just put 2016 engine in 2012 truck just had few changes but all good

Quality product, carefully packed and quickly shipped. Very happy customer here.

I was surprised when I removed the DPF/SCR and replaced it with a straight pipe with a high flow muffler… and it was quiet. But I don’t have to worry about getting pulled over. Easy install, very straightforward. Would buy again. Shipped fast! But if you want louder pipes, consider the straight pipe.

Great product, well made, fit is perfect. Hardware sent is a little short in my opinion so I reused factory hardware. Turned out great.

Great product and comes with everything you need.

In my opinion best bang for your buck and very trustworthy company and had in stock

Great kit but I like the black bracket for the water pipe and exhaust temp sensor.

The installation is easy and smooth.

They make the parts affordable thank the lord, got the website from my mechanic but he never tried them yet- I gave them a shot now I get it

I’ve bought this part two times now for different trucks and it works great highly recommend!

The exhaust sounds amazing. And very easy to install. Only complaint would be packaging. UPS destroys the box when delivered, if there were better Cushioning within the box, less likely to be damaged.
