Mini 4WD Axle Spacer M4WD-03/LB Light Blue - compatible with Tamiya by 3Racing  [M4WD-03/LB]

Light-blue M4WD-03/LB axle spacer for Mini 4WD

The M4WD-03/LB spacer is a purpose-made washer sized to interface with M6.4 x 1.7 ball bearings used in many Mini 4WD applications. It is supplied as a straightforward, colour-coded spare to sit between bearings and nearby chassis or axle components where controlled axial spacing is needed.

Hobbyists who sort parts or perform routine maintenance will find the light-blue finish helps speed identification. The spacer keeps its function focused on bearing clearance rather than changing drivetrain geometry.

Fitment advice: designed around the M6.4 x 1.7 bearing dimension. It does not modify bearing internals. Always fit on clean surfaces and check for debris to prevent accelerated wear.
