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 2127 reviews
Love this differential fits amazing and looks even better so glad with my choice wouldn’t have it any other way honestly
I went with the 3" down pipe as well as the lb7 style up pipe for my 06 lbz.
highly recommend the up pipe, much better than the block off plate.
paired with the 3" down pipe is a must, I can tell my truck is building boost quicker and getting the exhaust out faster.

Simple install and works great

This was a super simple install. Took about 45 minutes, which includes removal of old exhaust. Exhaust fit well and seems to be made of high quality. Truck sounds awesome!

Exhaust fit great, great quality, sounds great, used with the muffler and is surprisingly quiet! Will be ordering more in the future!

Buen producto buena calidad

This is very good quality and the shipping was very quick. Definitely trust this site and will do business with SPELAB again.

Customer service support was great, and the product worked as described and the extra heater hose included was a life saver in helping me fix my HVAC heater when the factory connector broke.

I am happy with my purchase. Looks to be a quality part, and definitely can’t beat the price .

Looks pretty%2C install wasn’t bad other than the very last fuel line which isnt spelab’s fault lol%2C i find that the turbo spools faster and power comes in harder. Less black smoke now that she can breath%21%21%21 Overall very pleased%21%21%21

Had it installed on my ‘99 Camaro Z28. Sounds really nice at WOT, and the tone is very deep at idle. Was decently made, electric motor has held up nicely from water over the past few months. Wireless fob has better range than my cars keyfob lol. Assembly was straight forward, but there were more parts included than the instructions had said. Would buy again for another vehicle with a v8.

I love this product. Easy install. All hardware was perfect. It’s a beautiful product and has qualities that I love. Fill and drain plugs and mostly the sight port.

Awesome product and very easy to install also the best part about this kit is that it does work with other added on fuel filter AFTER the cp4 so you get best of both worlds🙏🏽

The 5' exhaust with the 6" tip looks and sounds really good. The egr delete its made really nice and fits perfect and looks good.
The ccv it's easy to install it fits and looks good too. Thanks soo mutch

It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore
