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.
