This aluminum gear box is a direct-fit aftermarket replacement designed for scale RC use with the specified Tamiya DT chassis. The unit is supplied in a gun metal finish and targets hobbyists who want a rigid, machined housing to replace the stock plastic housing for improved durability and predictable gear alignment.
Installation focuses on swapping the original wave or plastic gearbox with this machined housing while retaining existing spur and pinion gears, bearings, and internal shafts. Basic disassembly of the DT-series center pod is required, and standard hex drivers and a clean workspace are recommended. This part is strictly an RC accessory and should be used only on model vehicles.
In tuning, a stiffer gearbox housing reduces flex under load, which can help maintain consistent mesh between spur gear and pinion, benefiting traction and gear life when paired with correctly sized bearings and motor/ESC setups. Check gear mesh and bearing preload after installation to avoid premature wear.
Use this gearbox where a stronger, machined housing is required to support higher loads or to improve drivetrain consistency on Tamiya DT-series models, confirming fit and gear mesh during installation.
