M4WD-03/GO gold M6.4 x 1.7 spacer for Tamiya Mini 4WD systems

This M6.4 x 1.7 spacer is designed for use in Tamiya Mini 4WD bearing and hub assemblies. It provides a precise axial gap between bearings or between a bearing face and a hub so that axle offset remains consistent. The gold term refers to the external finish and does not by itself indicate material composition.

Expert builders will recognise the spacer as a dimensional tool used in stacked configurations where small spacing differences can affect alignment and bearing preload. Treat it as a spacing and visual component rather than a structural upgrade, and confirm fit before installation.

Compatibility note: intended for Mini 4WD bearing and axle assemblies that accept an M6.4 interface. Check clearances around wheels, rollers and chassis rails to avoid contact with spacer stacks.

How precise is the 1.7 thickness for setup work?

The 1.7 mm thickness is a nominal axial value. Using the correct thickness helps keep bearing preload and wheel geometry predictable.

Will this spacer prevent bearing movement?

It helps maintain axial spacing but will not replace proper bearing clips or press fits. Use the spacer alongside secure mounting methods.

Is the gold colour plating or anodising?

The finish is described as gold; check manufacturer details for specifics on plating or anodising rather than assuming a particular process.

Do I need to recheck alignment after fitting this spacer?

Yes, always bench-check wheel runout and axle alignment after adding or changing spacers to ensure smooth rotation.
