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

This is the gear differential set that comes standard with the TRF420 chassis. By making the differential case as thin as possible while maintaining the 37T drive ratio, we have achieved a weight reduction of approximately 1.5g. The gears, differential cups, gaskets, and other parts inside the gear differential can be used with the TRF419 series.
