What kind of oil does this differential cover require?

This cover includes two quarts of aFe Pro Guard D2 Synthetic 75W-90 gear oil, which exceeds API GL-5 performance requirements. It's suitable for both open and limited-slip differentials. You can purchase additional quarts of this oil as needed.

Does this cover come with a gasket?

The manufacturer provides the necessary installation hardware, but does not specify whether a gasket is included. Refer to the manufacturer's installation instructions for details.

How does the calibration plug work?

The calibration plug is set to the factory oil level. This eliminates the possibility of overfilling the differential, which can cause foaming and reduced lubrication.
