If you work on setup and tuning, the 3Racing 20T counter gear is a practical upgrade for the Tamiya FF-03 chassis. It integrates cleanly into the factory layout and helps the drivetrain run with less resistance for steadier acceleration and control.
The tooth count and profile are chosen to spread load through the gear train, which reduces concentrated wear and helps keep surrounding parts in better condition during regular use.
Whether used to test a new setup or kept as a spare for race day, the 3Racing 20T is built to withstand routine track demands and simplify mid-event repairs.
