TAMIYA Tractor Truck Gearbox Brass Gear Set TRU1200S by GPM  [TRU1200S]

Brass gearbox upgrade for TAMIYA tractor trucks

This aftermarket set includes brass replacement gears made to fit inside the gearbox housings of compatible TAMIYA tractor truck models. These gears act as mechanical tuning parts and do not change the electronic or motor specifications of the model.

Fitting the brass gears can shift gearbox response and gearing feel in a measurable but subtle way. Installation involves gearbox access and careful reassembly, with attention to gear mesh and bearing condition to keep the drivetrain dependable.

For hobbyists wanting a reliable, mechanical way to fine tune gearbox behaviour on supported TAMIYA tractor trucks, these brass gears are a direct swap; always check mesh and bearing condition during fitment.
