3Racing M4WD-03/LB light-blue bearing spacer for Mini 4WD axles

This 3Racing M4WD-03/LB spacer is a purpose-specific washer sized to interface with M6.4 x 1.7 ball bearings used on Tamiya Mini 4WD assemblies. It is intended as a simple, color-coded spare part to sit between bearing and adjacent chassis or axle components where a tight axial fit is required.

Experienced hobbyists and collectors will find the part useful for parts sorting and routine maintenance. The light-blue finish provides quick visual identification when organising spares, and the spacer form factor keeps installation scope limited to bearing-clearance and axial spacing tasks rather than drivetrain modification.

Compatibility notes: the spacer is designed around the M6.4 x 1.7 bearing dimension commonly used in Mini 4WD setups. It does not alter bearing internal dimensions or bearing type. Keep bearings and mating surfaces free of grit during installation to avoid premature wear.

What exact bearing size does this spacer fit?

The spacer is specified for M6.4 x 1.7 ball bearings as used in many Tamiya Mini 4WD assemblies. Confirm bearing outer diameter and width before use.

Is this spacer compatible with all Mini 4WD chassis?

It is intended for bearings with the M6.4 x 1.7 dimension. Compatibility depends on axle and chassis clearances; verify you have adequate axial space before installing.

Can this spacer affect wheel alignment or rolling resistance?

When sized and fitted correctly, the spacer maintains intended bearing clearance. Improper placement or debris can introduce misalignment or increased resistance, so install cleanly and check runout.

Is the light-blue color functional or only identification?

The light-blue hue is provided for visual identification of the spacer size/type. It is not described as a performance feature.

Should I use this spacer with sealed bearings?

The spacer can be used with sealed or open bearings if the dimensions match. Ensure it does not contact seals in a way that would compromise bearing sealing or lubrication.

Any storage or handling recommendations for spare spacers?

Store spacers in a clean, dry container separated by type or color. Avoid mixing with loose debris and check each spacer before reuse for nicks or deformation.
