TAMIYA Tractor Truck Brass Gear Replacement TRU1200S by GPM  [TRU1200S]

Aftermarket brass gears for TAMIYA tractor truck gearboxes

This aftermarket gear pack provides brass replacement gears sized for fitting inside the gearbox assemblies of select TAMIYA tractor truck models. These parts are intended as mechanical drivetrain components and do not modify motor or ESC specifications.

Installing the brass gears can produce modest changes to gearbox response and effective gearing, useful for tuning. Access to the internal gearbox is required and installers should verify gear mesh and bearing condition to avoid premature wear.

For enthusiasts seeking a practical gearbox-level adjustment on compatible TAMIYA tractor trucks, these brass gears provide a simple swap; confirm fit, mesh and bearings during installation.
