3Racing M4WD-33/LB double aluminum rollers for 8-9mm shafts

These double aluminum rollers are an aftermarket roller set intended for Mini 4WD use. The pieces are machined from aluminum with an anodized light blue finish. The body text focuses on compatibility, fitment considerations, and practical handling notes that experienced hobbyists rely on when selecting roller hardware for common racing chassis such as Super-II, MA and MS.

Mounting uses standard 8-9mm spacing; check shaft and spacer clearances against your chosen damper or stay assembly. The finish reduces visible wear compared with bare metal, and the machining tolerances tend to produce repeatable concentricity when installed correctly. For collectors, the color and finish are useful when building display builds with a consistent color theme.

This product is supply-level hardware rather than a chassis-specific upgrade. Confirm thread sizes and spacer combinations before final assembly. Avoid using these rollers on Wild Mini 4WD or Scale Mini 4WD series where such metal rollers are outside intended use.

Are these rollers compatible with Super-II stays and standard 3mm shafts?

Compatibility depends on the stay hole layout and shaft diameter. These rollers are specified for 8-9mm spacing; verify your stay and spacer stack before use and confirm the roller bearing or bushing inner diameter matches your shaft.

What maintenance is recommended for anodized aluminum rollers?

Clean with a soft brush and isopropyl alcohol to remove dust and grime. Avoid abrasive cleaners that can strip anodizing. Periodically check for play at the roller bore and replace if wear affects concentricity.

Do these rollers include bearings or require separate bushings?

The listing describes aluminum rollers; confirm whether bearings or bushings are supplied with the set from the vendor. If bearings are not included, select appropriate 2.3mm or 3mm internal bearings that match the roller bore.

Will the weight of aluminum rollers affect handling noticeably?

Aluminum rollers add mass compared with plastic rollers. For experienced tuners this can change inertia at the corners; consider balancing with lighter components elsewhere if mass distribution is a concern.

Is the light blue anodize purely cosmetic or does it provide corrosion resistance?

Anodizing is both cosmetic and protective. The light blue finish is an anodized coating that helps resist surface corrosion and wear compared with untreated aluminum, though it will still wear under abrasive contact.

Can these rollers be mixed with plastic rollers on the same build?

Mixing materials is common; ensure the combined dimensions and mounting alignments keep the car stable. Check roll resistance and contact points during a trial run and adjust spacers or shims if needed.
