How often should I change the fluid in this differential cover?

Refer to your vehicle's service manual for recommended fluid change intervals. However, with the increased fluid capacity of this aFe cover, you may be able to extend the intervals slightly, especially if you're not towing or hauling heavy loads. Always inspect the fluid regularly for signs of contamination.

Does this differential cover come with a gasket?

No, this differential cover does not include a gasket. You can reuse your factory gasket if it's in good condition, or purchase a new gasket separately. Refer to the manufacturer's installation instructions for any sealant recommendations.

What type of gear oil should I use with this differential cover?

Refer to your vehicle's service manual for the recommended gear oil type and weight. Using the correct fluid is crucial for proper lubrication and long-term durability of your differential. The increased capacity of this cover means you'll need approximately 2 quarts for a fill.
