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

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

The M4WD-34/PK double roller kit is CNC-style machined from aluminium and finished with an anodized pink coating for a matched look with other metal upgrades. The paired-roller layout helps reduce body roll on corner entry for cars that accept 12-13mm rollers. The set is aimed at hobbyists wanting a tougher spare or a consistent aluminium aesthetic.

These rollers are compatible with a wide range of Tamiya Mini 4WD mounting patterns that use 12mm to 13mm bores; always check your stay hole spacing, spacer clearance and screw types before fitting. You can use sealed bearings or open bushings depending on the shaft hardware in your build. Remember this is an accessory, not a full car kit.

Fitment notes include checking shaft diameter and spacer thickness so the rollers clear body panels. Use appropriate screws or locknuts and watch for contact between aluminium parts and steel spacers which can cause fretting; inspect mating surfaces regularly. Keep anodized surfaces clean with a soft brush to maintain the finish.

For display collectors the anodized pink offers a pleasing match with other aluminium parts. For racers and builders, confirm bearing selection and shaft fit before purchase to avoid extra workshop time. This roller set replaces worn plastic rollers or complements aluminium upgrade sets.
