M4WD-03/GO gold M6.4 x 1.7 spacer for use with Tamiya Mini 4WD

This M6.4 x 1.7 spacer is a compact bearing spacer intended for Tamiya Mini 4WD applications. It provides a fixed axial gap between bearings or between a bearing and hub to ensure consistent axle positioning. The gold description refers only to the finish visible after assembly and should not be taken as a material specification.

Seasoned Mini 4WD tuners will use it in stacked assemblies where small spacing changes influence alignment and bearing preload. It is designed for spacing duties and visual match, not as a structural upgrade. Check bore and hub clearances on your parts before installation.

Fitment note: suitable for Mini 4WD bearing and axle assemblies accepting an M6.4 outer interface. Confirm clearance where wheels, rollers, or chassis rails are close to spacer stacks.

How thin is the spacer and why does thickness matter?

The 1.7 value is the axial thickness. Small changes in thickness alter bearing preload and lateral positioning, which can affect wheel alignment.

Will the gold finish wear off quickly?

Finish durability depends on the base material and any coating. Treat the finish as cosmetic unless the maker specifies a protective treatment.

Does the spacer add strength to the axle?

No, it is a dimensional component. It helps maintain spacing and alignment but is not intended as a load-bearing reinforcement.

Any tips for stacking multiple spacers?

Mark spacer order, test wheel runout on a bench, and ensure rollers and hubs clear the stack to avoid rubbing.
