Mini 4WD Bearing Spacer M6.4 x 1.7 - M4WD-03/RE by 3Racing  [M4WD-03/RE]

M4WD-03/RE red M6.4 x 1.7 spacer for bearing alignment

This red M6.4 x 1.7 ball bearing spacer is a cost-effective replacement part intended for Mini 4WD assemblies where consistent axial spacing is critical. It is supplied as a dedicated spacer component and is not a complete bearing or axle; use it to control bearing clearance and positioning in wheel hubs, rollers, or gear stacks on 1/32 scale Mini 4WD models.

Experienced builders should treat this spacer as a dimensional part: verify the M6.4 x 1.7 measurement against the specific bearing and hub on your model before fitting. The spacer suits Mini 4WD setups that accept M6.4-style separators and will not alter motor or chassis geometry by itself.

Installation tips: keep axial contact surfaces clean and support bearings during assembly to prevent side loading. The red finish is cosmetic and does not indicate different mechanical properties. Use precise measurement when replacing spacers in tight-tolerance stacks where clearance and endplay matter.
