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

Refer to your vehicle's service manual for the recommended fluid change intervals. Factors like towing, off-roading, and overall driving conditions can affect how often you need to change the fluid. Using a well-built synthetic gear oil can also extend the change interval.

Does this differential cover come with a gasket?

This aFe differential cover does not include a gasket. Refer to the manufacturer's installation instructions for any sealant requirements.

Is this differential cover compatible with aftermarket suspension modifications?

This differential cover is designed to fit in the factory location. However, if you have aftermarket suspension components, especially those that alter the axle position or travel, check for any potential clearance issues. Always cycle the suspension fully after installation to confirm there is no contact.
