For hobbyists wanting longer service life, the Tamiya 54629 - 08 Module Steel Pinion Gear (19T) is a solid upgrade. Made for DT-03 and DT-02 chassis, this steel pinion replaces standard aluminium parts and helps reduce frequent gear swaps.
Steel pinions resist wear better under repeated stress, so teeth stay accurate longer during aggressive runs. That toughness lowers maintenance frequency and keeps your drivetrain working reliably.
This pinion is produced to match Tamiya DT-03 and DT-02 gearset geometry. It arrives with a grub screw for secure mounting, making it straightforward to install and lock in place for track or club use.
