TAMIYA Tamiya TRF414M TA04 Ball Differential Used This is a ball differential with black lightweight differential joints. It also has black differential joint rings. I think it will match a modern black-themed chassis. Since it is used, there are scratches to some extent. It has been overhauled and maintained with bearing oil, ball differential grease, and VG thrust bearing grease, so it can be used immediately. I have another one of the same item, so please comment if you need it. I may suddenly end the listing because I might use it.
