SKU: N/A Category:


Single speed gearbox conversion kit for 1/14 scale Tamiya RC trucks.

This 7.2v motor and gearbox spins at 345rpm giving a good walking pace speed to the Tamiya truck ideal for small and large layouts.
Available in two torque ratings, 3.1Nm or 4.1Nm, the highest torque available on the market at this voltage.
Unlike other gearboxes this allows you to use your standard 5mm drive cups or aftermarket 5mm driveshafts.
The gearbox bracket bolts in place of the standard Tamiya 3 speed transmission however may need modification to clear body mounts depending on body style.

16/09/2022 Update: Our new design of bracket should fit most Tamiya kits without modification however some trimming may still be required.

Kit contains:

  • Motor
  • Gearbox
  • Gearbox Mounting Plate

The kit comes pre-assembled ready to install.

Now also available as a “No Motor” option where you will be supplied just the gearbox and mounting plate to assemble on to your own 540 size motor.
Your motor output shaft will need to be shortened so it only measures 11.8-12mm from the end of the shaft to the motor mounting face before having the pinion gear pressed on.

The HobbyWing QuicRun Fusion brushless Motor/ESC works brilliantly with our gearbox conversion and makes for a compact combination.
