3Racing M4WD-35/LB double aluminum rollers for Mini 4WD 4WD chassis, 16-17mm light blue  [M4WD-35/LB]

3Racing M4WD-35/LB double aluminum rollers, light blue finish

These double aluminum rollers from 3Racing are a direct-fit accessory intended for Mini 4WD use. The unit features paired rollers in a compact space-saving arrangement and is presented in a light blue anodized finish. The writeup below assumes familiarity with Mini 4WD mounting options and common roller bracket geometries.

Construction is typical of aftermarket aluminum rollers: machined roller bodies paired on a single mounting assembly. For experienced builders the main considerations are bracket compatibility, axle clearance, and whether the roller stack aligns with existing stabilizers or guide pins. The 16-17mm diameter range is commonly used where compact clearance is required.

When integrating these rollers into an existing Mini 4WD setup, check axial play and the type of spacer or bearing you currently use. The rollers are suitable for standard roller brackets and most aftermarket bearing assemblies, but verify nut and shaft clearances before final assembly. The light blue anodizing is primarily cosmetic; treat the finish as an aesthetic selection rather than a performance enhancement.

This component is presented as a replacement or appearance part rather than a complete performance upgrade. Collectors replacing worn roller parts or builders refining a display model may find the color and machined finish useful for matching a specific build theme.
