What kind of gear oil is included?

The included gear oil exceeds API GL-5 specifications, so it's suitable for both open and limited-slip differentials. Using the included oil ensures proper lubrication and performance for your specific application. Always refer to your vehicle's manual for specific oil requirements.

How does the calibration plug work?

The calibration plug is set to the factory oil level. This prevents overfilling, which can cause leaks and damage to the differential. Just fill until oil reaches the calibration plug, and you're good to go.

How often should I inspect the oil level?

aFe recommends checking the oil level periodically, especially if you're using your truck for towing or off-roading. The sight glass makes it easy to check the level without removing any plugs. If the oil level is low, top it off with a GL-5 rated gear oil.
