Red 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 accurate bearing clearance

The red M6.4 x 1.7 ball bearing spacer is a dedicated replacement spacer for Mini 4WD assemblies that need consistent axial clearance. It is provided as a spacer element only and is used to set bearing position in wheels, rollers, or gear stacks rather than serving as a bearing or axle.

Confirm the M6.4 x 1.7 dimension against your specific bearing and hub bore before fitting. This spacer is intended for Mini 4WD configurations that accept M6.4 separators and will not alter drivetrain geometry by itself.

Fitment guidance: support bearings during installation and ensure mating surfaces are free from dirt to prevent side loading. The colour is decorative only; check material and tolerances if durability is a concern.
