How does the increased oil capacity benefit my truck?

The aFe differential cover increases the oil capacity, which helps to keep your differential running cooler, especially under heavy use. Lower temperatures extend the life of the oil and the internal components of the differential.

What maintenance is required for the aFe differential cover?

The magnetic drain plug should be cleaned during each oil change to remove any captured metallic particles. Periodically inspect the sight glass for oil level and condition. Refer to the manufacturer's instructions for specific maintenance intervals and procedures.

Does this cover come with new bolts or a gasket?

The product description does not specify whether new bolts or a gasket are included. Refer to the manufacturer's installation instructions for details on required hardware and installation procedures.
