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

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

This single-dimension spacer is intended to set and maintain axial position for M6.4 x 1.7 ball bearings used in Mini 4WD wheels and axles. The pink anodised colour is for identification only; no mechanical or tolerance data is supplied by the vendor.

For hands-on modders: fit the spacer where a consistent separation between bearing races is required or to replace lost factory parts. Verify that the spacer bore and outer diameter match your existing bearings and hub spacing before fitting. For critical stack height, assemble and measure axial clearance on a bench prior to refitting to a running chassis.

Compatibility note: made for standard Mini 4WD bearing applications. Do not assume interchangeability with custom axles or hub designs without checking. This accessory does not change chassis class or permitted modifications.
