While the Ford 9.75" rear end is one of the stoutest rear ends and axles in a half-ton truck, and while it's certainly able to handle nearly any application you have in mind for your awesome F150 or Raptor build, it's actually pretty annoying to actually live with, since it lacks a drain port and the fill port is placed on the side of differential housing and has this annoying tendency to rust itself to uselessness in places that use salt on the roads. That's why an F150 aftermarket differential cover is one of the most handy upgrades you can most handy upgrades you can make to a 9.75" equipped F150 or Raptor. Nearly all of these differential covers come with their own drain and fill ports, increased capacities, and revised designs that make them extremely effective upgrades over the stock cover. However, there's more than few to choose from which can make finding the right one for your kind of a pain.
