What is the purpose of a differential cover gasket?

A differential cover gasket creates a seal between the differential housing and the differential cover. This prevents gear oil from leaking out and keeps dirt and moisture from getting into the differential assembly.

Does this gasket come with any hardware?

This product is for the gasket only. You will need to reuse your existing differential cover bolts or purchase new ones separately.

What does AFM mean in relation to this gasket?

AFM stands for Active Fuel Management, a system that can shut down cylinders to save fuel. This gasket is specifically designed for differentials on vehicles equipped with this system, ensuring proper fitment and sealing.
