Gear Differential Ring – Ford (ys4z7f343fa)

Gear Differential Ring is a toothed component that transfers drive through a set ratio. Tooth count, pressure angle and hub offset are what make one gear interchangeable and another not.

Replace the Gear Differential Ring when you find chipped or spalled teeth, when the pattern shows contact concentrated at one end, or when the transmission is apart for another failure. Inspect the mating gear before refitting.

This Gear Differential Ring is listed as part ys4z7f343fa (Gears & Internal Parts). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is FORD dealer-sourced stock rather than an equivalent, so the number on the Gear Differential Ring traces straight back to the manufacturer.
