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

Black M6.4 x 1.7 spacer M4WD-03/BK for 1/32 Mini 4WD

This M4WD-03/BK spacer is a direct replacement intended for 1/32 Mini 4WD assemblies that specify M6.4 x 1.7 bearing spacing. The part is a simple axial spacer that sits between bearings or between a bearing and an adjacent component to keep correct axial position and alignment in common Mini 4WD drivetrain stacks.

Seasoned builders will recognise that a dedicated spacer produces repeatable bearing seating and helps cut down on sideplay caused by uneven stack heights. The black finish keeps a low profile with darker chassis and roller setups while serving as a practical spare for routine servicing or restoring older Mini 4WD models.

Compatibility notes: fit this spacer only where M6.4 x 1.7 bearing geometry is already specified for the axle or roller assembly. This is a part-level replacement for maintenance and fitment, not a performance tuning upgrade; always follow the bearing and axle specs of the host Mini 4WD.
