Designed for Jeeps, this AMC Model 20 PML cover follows the round shape of the stock cover and adds fins for heat dissipation.

Benefits:

  • Drain hole and magnetic drain plug included
  • Fins for heat dissipation and classic styling
  • Heavy duty sand cast aluminum construction
  • Extra capacity
  • Machined gasket flanges to provide a uniform clamping force on the gasket surface for a secure seal.



Construction of PML Cover

PML differential covers are aluminum, which is a great material for heat dissipation. For rock crawling and offroading, cast iron and steel are strong and protective of the differential internals although these metals are not good at heat dissipation. Aluminum is a much softer metal and a PML cover would need a shield or cage for off roading or rock crawling.

Fill/Level Check Hole

This cover was designed for vehicles with a a plug on the driveshaft side of the differential where filling and level check is done. As with the stock cover, this PML cover does not have a fill/level check hole.
