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, and all Mag-Hytec parts are covered by a lifetime limited warranty.  Depend on Mag-Hytec when you're pulling a heavy load.

Avoid costly reapirs - Extend the life of your Vehicle - Expand oil Capacity - Runs Cooler, Lasts Longer


  • Average of double the fluid capacity
  • Ease of Service
  • The dipstick is knurled for quick removal, the flat is marked low/high to check lube level and a magnet, which acts as an open filter is in the lower end.  The MS 7/8 - 14 THD port is large enough to use for filling.
  • The magnet-filled drain plug is the same MS port as the dipstick.  Both the dipstick and drain are O-ring sealed.
  • The sending unit fitting is 1/8 pipe THD and shipped with a stainless pipe plug.
  • The calibration plug is centered on the serial number plate and approximates the stock cover fill plug for factory fluid level.
  • The O-ring is snapped into the inverted "V" groove for a positive seal without gasket or silicone.
  • Plugs, cap screws and washers are stainless steel in most applications.


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.

MAG-HYTEC PRODUCT WARRANTY:
All Mag-Hytec products are covered by a lifetime limited warranty to the original owner against defects in parts and workmanship. O-rings are covered for five years
