Spur Gear (46t Steel CNC Lightened Nb/Nt48 2.X)

Tekno RC is pleased to announce the availability of the new 46 tooth steel spur gear for the NB48 and NT48 2.X vehicles. This new spur gear provides taller gearing which increases overall top speed while reducing potential wheel spin. Less wheel spin improves grip and can enhance mileage in certain conditions. TKR9421 is CNC machined from high grade steel, black oxide coated and has the same design and Tekno RC durability as the stock TKR9419. This is a direct replacement for TKR9419 and requires no extra parts
