The Tamiya 53814 NDF-01 2-Speed Transmission Gear Set (54T/57T) OP-814 gives hobbyists a practical way to adjust gear ratios for different conditions. Made for the NDF-01 chassis, the set includes both 54T and 57T driven gears so you can swap gearing to prioritise acceleration or top speed.
Swap between the included gears to favour quicker acceleration or higher straight-line speed depending on track layout or terrain. The machined gears deliver reliable meshing and long service life when installed correctly.
Installation is straightforward on the NDF-01 chassis and requires no major modifications. This upgrade suits builders who want a quick gearing change to adapt to different surfaces and racing formats.
