Secure Your TRF421 Spur Gear with Tamiya 3451527

The Tamiya 3451527 Spur Gear Nut is a tailored component for TRF421 chassis users who want dependable gear retention. It holds the spur firmly to limit side-to-side movement and helps maintain even mesh throughout a run. Swap it in during gearbox servicing to keep drivetrain behaviour predictable and consistent.

Is this the original replacement nut for the TRF421?

The 3451527 is produced to match the TRF421's requirements and serves as a direct style replacement to secure the spur gear correctly.

What performance benefits can I expect?

You can expect reduced gear play and fewer incidents of spur slip, which contributes to steadier acceleration and braking response.

Any advice for fitting without stripping threads?

Thread the nut on by hand first, then tighten with a small driver to a controlled feel; avoid excessive force and inspect threads for damage.

Where should I look for spare parts if I lose one?

Check specialist RC retailers or parts suppliers that stock Tamiya components; keeping a spare in your tool box is a good idea for events.
