The TKR9296 87.5mm Front Center Universal Driveshaft is a hardened steel center drivetrain shaft designed for Tekno RC 1/8 scale nitro buggy platforms, specifically the NB48 2.0, NB48 2.1, NB48 2.2, NT48 2.0, and NT48 2.2 vehicles. It is used in the front center drivetrain position, connecting the center differential to the front gearbox to deliver power efficiently while allowing smooth suspension movement through a universal joint design. This driveshaft is a direct replacement OEM part and is engineered specifically for those chassis, meaning it is not a universal fit for other Tekno platforms due to its fixed 87.5mm length and geometry requirements.
