TKR5151 Straight Cut Differential Ring Gear (40T)

The TKR5151 Straight Cut Differential Ring Gear (40T) is a CNC-machined hardened steel ring gear used in Tekno RC 1/8 scale platforms, including the EB48.2, EB48.3, NB48, NB48.3, ET48, SCT410, SCT410.2, SCT410.3, and MT410 2.0 vehicles. It is part of Tekno’s straight-cut differential gear system and is designed to work only with the matching straight-cut pinion gear (TKR5152) to deliver smoother, quieter, and more efficient drivetrain operation compared to standard bevel-cut gears. This ring gear is used inside the front or rear differential assembly and is a direct OEM replacement or upgrade for compatible Tekno differentials, requiring no modification when used with the correct matched components.
