Mag-Hytec heavy-duty differential covers are designed to provide increased lubricant and cooling capacity for hard-working recreational and service vehicles. They are cast in A356-T6 aluminum and feature a texture powder-coated black finish with machined cooling fins for improved heat dissipation. A suspended magnet acts as a filter to contain metallic particle debris, keeping the fluid cleaner and extending component life. These covers are fitted with ARP 568 O-rings for superior sealing, often eliminating the need for gaskets or sealants. All hardware is 303-type stainless steel. Mag-Hytec covers come fully assembled and are backed by a limited lifetime warranty.
