3Racing M4WD-30/RE 1/32 Mini 4WD 4WD-compatible 13mm aluminum ball race rollers (ringless) - spare roller part  [M4WD-30/RE]

3Racing M4WD-30/RE 13mm ringless aluminum ball race rollers, red

These ringless 13mm aluminum ball race rollers are an aftermarket spare part produced by 3Racing for Mini 4WD use. The component presents a compact, low-profile roller designed to sit on standard roller mounts used across common 1/32 Mini 4WD setups. The red-anodized aluminum outer body and exposed ball element are the visual and structural traits to note.

Compatibility and fit vary by chassis and mounting method. The roller is intended as a replacement or aesthetic swap for builders and collectors who maintain Tamiya Mini 4WD vehicles. Installation requires standard roller hardware and alignment to the existing roller stay; the part does not include mounting screws or spacers unless supplied by the installer.

Material and finish are typical of 3Racing aluminum accessories: machined outer shell with an exposed ball assembly. The ringless profile changes how the roller contacts guide rails and lane walls compared with ringed rollers. Evaluate clearances on tuned chassis before use to avoid unintended contact with bodywork or stabilizers.
