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.

Best investment i bought and proud to have from SPELAB
Instructions were great, could
Be more detailed but overall great product, install wasn’t bad at all, unfortunately snapped oil dipstick tube following instructions but other than that I would say the plugs in the intake could’ve been put in prior rather than leaving room for install error
Very nice
Good products great pricing
Works great, find out how to wire it on YouTube if you aren’t sure, super easy though only two wires
this 2017 3500 Ram with now 111274 miles was used by PO to pull 5th wheel and now it pulls a 30 ft airstream TT.. I change out fluid at 96K with OEM cover and started looking for replacement.. this is great with magnetic drain plugs which is a great help as we change out oil every 35K miles as we tow a lot..
This new alum cover with fins is much like the AAM unit used on teh HO engines from factory with not quite the amount of and placement of fins but in the end this accomplished the goal of keeping the fluid cooler especially when towing.
One thing i did notice was the no actual instruction on what was proper level of oil in sight glass.. Usually on OEM cover you fill till the oil dribbles out the fill plug on cover and that if good..
on this model I noticed the sight glass was lower than the OEM plug determining the level need to be not the middle of the sight glass but at the TOP of the sight glass.. just saying.. the inside has fluid diversion fins so help move the oil to ponion gear and the side bearing on housing..
The fit and finish are great and it looks super cool now in the alum color.. I though about spray painting and sanding the edge of the fins to have that nice contrast but left it silver.
highly recommend and the price is right..
Order came in a few days earlier than the expected delivery day pretty easy install it makes the engine may look a lot better
I purchased a pair of Spelab Electric Cutouts for my BMW. Everything in the kit was shipped quickly, was perfectly packaged and the quality of their product is top notch. I installed the cutouts and I couldn't happier with the way they work. I was even able to pair the remote to the Homelink buttons to open and close the valves.
Hoping to gain a sponsorship soon I use yalls parts on my personal build and customers builds
Very good quality kit and was easy to install!! I highly recommend it!!
Excellent quality product that definitely delivers a difference in throttle response. You can tell that the engine is breathing much better. I highly recommend this to everyone out there. Shipping was fast too!! And to top it off, the dreaded engine killing grid heater plate is gone for good! Look how bad the grid heater was after only 46,000 mi. You can barely see thru the grids. Ridiculous design by Cummins/Ram. They should be ashamed for putting that piece of junk on such a good engine. Next up, turbo tubes!
Fit my 08 6.4 extended cab just fine. Sounds great with a 5x7 tip
I have always used there products and customers always are happy
Was on the fence between the 4 or 5…but definitely glad I went with the 5! Fits perfect and sounds amazing!!
Wow. That says it all. Fast shipping, looks great big thing is what a difference it makes from stock things just act different with the more air flow.
