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

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

This one-size spacer holds the inner bearing races at a fixed separation for M6.4 x 1.7 ball bearings in Mini 4WD wheel and axle assemblies. The pink anodised finish is intended for identification and does not imply altered mechanical properties; the seller provides no material or tolerance data.

For regular users: install the spacer where a precise gap between bearing races is needed or to replace missing factory spacers. Always check bore compatibility and external diameter fit with your bearings and hubs before installing. If you need exact stack height, assemble and measure the unit on a bench to verify axial clearance and runout prior to fitting to a running chassis.

Compatibility reminder: intended for common Mini 4WD bearing setups. Do not assume it will fit customised axles or non-standard hubs without testing. This item is an accessory only and does not modify chassis classification or allowed mods.
