Tamiya RC Spare Parts TRF420 Gear Differential Set 51649 No.1649 SP.1649

This is a gear differential set that is standard equipment on the TRF420 chassis. By making the wall thickness of the differential case as thin as possible while maintaining the same drive ratio as the 37T, we achieved a weight reduction of approximately 1.5g. TRF419 series parts can be used as is for parts such as gears, differential cups, and gaskets in the gear differential.
