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

M4WD-03/PK pink M6.4 x 1.7 bearing spacer for Mini 4WD hubs

This single-size spacer locates and maintains axial separation for M6.4 x 1.7 ball bearings used in Mini 4WD wheel and axle assemblies. The pink anodized finish serves as a visual identifier; no material or tolerance claims are provided by the seller.

For experienced builders: use these spacers where a fixed gap between inner races is required or to replace factory spacers that are missing or worn. Check bore and outer diameter compatibility with your bearings and wheel hubs before fitting. If exact stack height matters, assemble parts on a bench and measure axial clearance and runout before reinstalling on a running car.

Compatibility note: designed for generic Mini 4WD bearing applications. Do not assume fitment with modified axles or non-standard hub designs without verification. This is an accessory part only and does not alter chassis classification or permitted modifications.
