Mini 4WD Compact Double Rollers M4WD-35/LB light blue anodized by 3Racing  [M4WD-35/LB]

3Racing M4WD-35/LB double aluminium rollers with light blue finish

These double aluminium rollers are a compact aftermarket option for Mini 4WD cars. The paired rollers are mounted closely to minimise profile and are supplied in a light blue anodized coating. The notes below assume basic familiarity with popular Mini 4WD roller mounts and bracket layouts.

Construction is typical: machined roller bodies paired on a single mounting carrier. Key installation checks for experienced hobbyists include bracket compatibility, axle clearance and correct stacking so the rollers do not contact stabilisers or guide pins. The 16-17mm diameters suit low-profile applications.

When fitting to a running car, verify axial play and the type of spacer or bearing currently used. These rollers are compatible with many standard brackets and common bearing assemblies, but confirm shaft diameter and nut threads before torqueing down. The anodised light blue is cosmetic and not a performance modifier.

This component is best treated as an appearance or replacement part rather than a complete performance upgrade. Builders updating display models or replacing tired roller parts will appreciate the machined look and colour matching options.
