Tekno RC is adding a 46 tooth steel spur gear for the NB48 and NT48 2.X trucks. The taller gearing bumps top speed and cuts wheel spin. Less spin means more grip, and in some conditions it can stretch your mileage. It is CNC machined from high grade steel, black oxide coated, and built with the same design and durability as the stock TKR9419. It is a direct replacement for TKR9419 and needs no extra parts. NB48 2.0 and NT48 2.0 use: remove the small nubs on the bottom of TKR9310B, then run it with the TKR9310B split center diff mount (NB48 2.1) and the TKR9115 or TKR9115B differential case (F/R/C, all 2.x).
