TKR9416B – Gearbox (-2mm, F/R, EB/NB/ET/NT48 2.x) Tekno RC is pleased to announce the availability of a -2mm gear box for all 2.X 1/8th scale vehicles! This gearbox lowers the diff height, which improves bump handling and provides a smoother, more consistent driving experience, especially mid-corner. TKR9416B requires the 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. We recommend utilizing TKR9054B +/-2 rear hubs when using this gearbox with the NB/EB48 buggies. The combination of TKR9416B and TKR9054B improves overall grip, stability, and predictability in the rear end.
