Mini 4WD Compatible 13mm Ringless Aluminium Ball Rollers M4WD-30/RE by 3Racing  [M4WD-30/RE]

M4WD-30/RE 13mm ringless aluminium rollers, red

These 13mm ringless aluminium ball race rollers serve as an aftermarket spare for Mini 4WD models. The low-profile rollers are intended for standard 1/32 Mini 4WD roller mounts and offer a compact alternative to taller ringed rollers. The red-anodized aluminium outer shell with an exposed ball assembly is the primary visual and mechanical detail.

Compatibility and fit depend on chassis design and mounting method. Use the rollers as replacements or visual upgrades for Tamiya Mini 4WD cars, noting that mounting screws and spacers are not included and must be chosen to suit your setup. Proper alignment to the existing roller stay is required during installation.

Construction follows common machined aluminium accessory practice, pairing a machined outer body with an exposed ball element. The ringless profile alters how the roller contacts guide rails and lane walls compared with ringed options; always verify clearances on tuned or low-clearance chassis to avoid unwanted contact.
