How does the calibration plug work?

The 1/8" NPT calibration plug is set to the factory fluid level. Once you've filled the differential, you can remove the plug to ensure you don't accidentally overfill it. This helps maintain optimal performance and prevents potential damage.

What maintenance is required for this differential cover?

Regularly inspect the differential cover for any signs of damage or leaks. The magnetic drain plug should be cleaned periodically to remove any accumulated metal particles. Refer to your vehicle's service manual for recommended differential fluid change intervals.

Does this cover come with a gasket?

The manufacturer includes the necessary hardware for installation. However, it's always a good idea to refer to the manufacturer's installation instructions to determine if a new gasket or sealant is recommended for your specific application.
