Steel Core Ford 9 Inch Housing 3rd Member Gasket

Steel core gasket for the Ford 9" Differential.
These are much better than your typical paper gasket. The steel core adds strength and rigidity, greatly decreasing the chance of tearing.

With my Detroit, I was going through the paper gaskets on a regular basis due, in no small part, to the constant stress of the locker loading up and unloading while in traffic. After tracking down this new gasket, I installed it some time ago and thus far, no disintegrating gasket and more importantly...no drips.
