The TKR9295 109mm Rear Center Universal Driveshaft is a steel center drivetrain shaft designed for Tekno RC 1/8 scale nitro buggy platforms, specifically the NB48 2.0, NB48 2.1, and NB48 2.2 vehicles. It is used in the rear center drivetrain position to transfer power from the center differential to the rear gearbox, replacing the standard dogbone-style setup with a universal joint design for smoother, more consistent power delivery and improved driveline efficiency under high-load racing conditions. The 109mm length is specific to the NB48 chassis geometry, making it a direct OEM replacement part intended for maintenance or rebuilds on compatible NB48-series vehicles.
