Mag-Hytec’s heavy duty differential covers provide increased lubricant and cooling capacity for hard working diesel trucks like yours. Mag-Hytec covers set your vehicle apart in both aesthetics and function – cast in A356-T6 aluminum and texture powder coated black with machined cooling fins. Mag-Hytec is synonymous with high quality differential covers and transmission pans, so you can depend on Mag-Hytec when you’re pulling a heavy load.
This cover is the correct cover for your 14 bolt-11.5 differential, even though there are only 12 holes. The top and bottom bolts have been removed for drain plug and temperature sending unit hole. Magnetic drain plugs trap worn gear material promoting fluid integrity. As the metallic components in transmissions and axles wear, they generate very fine particle debris that becomes suspended in the lubricating oil. A suspended magnet acts as a filter to contain these particles, keeping the fluid cleaner and extending component life. Periodic checking and cleaning of the magnet is recommended for maximum fluid service life.
