How does this differential cover improve performance?

The aFe Pro Series differential cover increases the oil capacity, which helps to keep the differential cooler. The cooling fins also help to dissipate heat. Cooler oil means better lubrication and reduced wear on the gears.

What is the purpose of the magnetic drain plug?

The magnetic drain plug captures any metallic particles that may be circulating in the oil. These particles can cause wear and damage to the gears. By capturing them, the magnetic drain plug helps to extend the life of your differential.

How do I check the oil level in the differential?

This cover includes a pre-installed sight glass that allows you to quickly and easily check the oil level. The calibration plug is set to the factory oil level to prevent overfilling. Refer to the manufacturer's instructions for proper fill levels.
