Very nice rear factory open differential with 3.91 ratio removed from a 2009 Toyota Tundra 4x4 with only 97k miles.

43 teeth on the ring gear. 11 teeth on the pinion.

Works like new with no leaks. Clean gear oil came out of it. Has nice tight bearing feel and no unusual indications of wear.

Professionally packaged for shipping UPS Ground to the Lower 48 USA. Costs more to ship elsewhere.
