The Tamiya 54629 - 08 Module Steel Pinion Gear (19T) is a practical upgrade for DT-03 and DT-02 chassis. Swapping aluminium for steel helps the drivetrain handle tougher running without frequent gear replacement.
Steel gears stand up better under load and keep tooth profiles intact through extended sessions. That durability reduces downtime and gives more predictable shifting and acceleration feel.
Made to match Tamiya DT-03 and DT-02 specifications, this pinion includes a grub screw for secure attachment. Fit carefully, set correct gear mesh and recheck the grub screw after the first short run.
