Fine-Tune Your TRF421 with the Tamiya 3451527 Spur Gear Nut

The Tamiya 3451527 Spur Gear Nut is a compact replacement made for TRF421 owners who want a reliable way to lock the spur gear in place. Built to tight tolerances, it helps prevent lateral gear movement under load and keeps mesh consistent during fast laps. Fit it when refreshing your drivetrain to maintain performance and reduce wear on spur and pinion teeth.

The 3451527 nut is produced for the TRF421 chassis and is optimised for that fit. Compatibility with other kits is not guaranteed, so compare dimensions before swapping between models.
By securing the spur gear firmly it reduces slippage and helps keep a steady gear mesh, which supports consistent lap times and reduces drivetrain wear.
Start threads by hand, avoid over-tightening, check the gear mesh after fitting and consider a light thread locker if you race on rough tracks.
