Tekno RC is pleased to announce the availability of a new -2mm gear box for all 2.X 1/8th scale vehicles! This new gearbox lowers the diff height, which improves bump handling and provides a smoother, more consistent driving experience, especially mid-corner. TKR9416B requires the new TKR9017B bulkhead cover and 2ea TKRBB05145 5x14x5 ball bearings. To avoid contact with the chassis, Tekno RC NB48 2.X buggies require a light grind (removing roughly 0.5mm of material) on the chassis below the ring gear. TKR9416B is a direct drop in for the EB/ET/NT48 2.X 1/8th scale vehicles and no modifications are necessary. It is recommended utilizing TKR9054B +/-2 rear hubs when using this new gearbox with the NB/EB48 buggies. The combination of TKR9416B and TKR9054B improves overall grip, stability, and predictability in the rear end. Vehicle Compatibility: TKR9416B - Gearbox is included with the EB48 2.2, ET48 2.2, MT48 2.0, NB48 2.2 and NT48 2.2 kits and can be used as a replacement part for those vehicles. This can be used with the EB48 2.1, ET48 2.0, NB48 2.1 and NT48 2.0 vehicles and should be a direct replacement for the stock part or used as a new feature. Please use the instruction manual for the kit(s) listed to verify compatibility and no additional items are necessary before purchasing.
