Tamiya Mini 4WD Double Aluminium Rollers 12-13mm for Super-II MA M4WD-34/PK by 3Racing  [M4WD-34/PK]

Double aluminium roller assembly M4WD-34/PK for Mini 4WD

The M4WD-34/PK is a double roller assembly machined from aluminium and finished in anodized pink to match aluminium upgrade sets. The paired rollers help control lateral body movement at corner entry on Mini 4WD cars designed for 12-13mm roller bores, making the set useful as a durable spare or aesthetic upgrade.

Compatibility extends to many Tamiya Mini 4WD mounting arrangements that accept 12mm to 13mm bores; always check stay hole spacing, spacer clearance and screw types before fitting. These rollers accept sealed or open bearings depending on axle and shaft hardware. This product is an accessory component rather than a complete kit.

During installation, verify shaft diameter tolerance and spacer thickness to ensure the rollers clear bodywork. Use appropriate screws or small locknuts to secure the rollers without binding. Inspect aluminium contact points for fretting if using steel spacers or hardened shafts, and clean anodized surfaces gently to preserve the finish.

Collectors will appreciate the consistent anodized pink aesthetic when combined with other aluminium parts. Builders should confirm bearing choice and shaft fit before ordering to avoid last-minute modifications. The roller set is intended as a simple aluminium replacement for worn plastic rollers or to match existing aluminium upgrades.
