This aluminum C hub is specified for TAMIYA DT-03 chassis layouts and carries the model code JR-DT304-BK. Finished in black anodized aluminum, it is intended as an upgrade option for DT-03 scale vehicles.
It replaces the front steering knuckle attachment point on the upright to deliver a firmer metal interface, which can change steering feel and may improve component longevity under track conditions.
Installation is normally a direct swap using the stock mounting points and hardware. Check wheel alignment and front geometry after fitting since the altered hub stiffness can influence camber and toe during tuning sessions.
