MAG-HYTEC'S heavy duty differential covers and transmission pans provide increased lubricant and cooling capacity for hard working recreational and service vehicles. MAG-HYTEC covers and pans set your vehicle apart in both aesthetics and function - cast in A356-T6 aluminum and texture powder coated black with machined cooling fins. Magnetic drain plugs trap worn gear material promoting fluid integrity. Each unit is fitted with ARP 568 O-rings for superior sealing. All hardware is 303 stainless steel, in most applications no gasket or sealant is required. Depend on MAG-HYTEC when you're pulling a heavy load.
