Tekno RC's 46 tooth steel spur gear for the NB48 and NT48 2.x vehicles. Taller gearing raises top speed while reducing wheel spin. Less wheel spin improves grip and can help mileage in some conditions. It is CNC machined from high grade steel with a black oxide coating, and has the same design and durability as the stock TKR9419. It directly replaces TKR9419 and needs no extra parts. NB48 2.0 and NT48 2.0 compatibility: this gear is compatible with those vehicles if the small nubs on the bottom of TKR9310B are removed and these parts are used: TKR9310B Split Center Diff Mount (NB48 2.1) TKR9115 Differential Case (F/R/C, all 2.x) or TKR9115B Differential Case (F/R/C, all 2.x)
