3Racing M4WD-34/PK double aluminum rollers for Mini 4WD

The 3Racing M4WD-34/PK is a compact double-roller set intended for use on Tamiya Mini 4WD vehicles. Machined from aluminum and finished in anodized pink, the set uses paired rollers to help stabilise body roll at corner entries on cars that accept 12-13mm rollers. The design is straightforward and aimed at hobbyists who need a robust spare that matches existing aluminum parts in appearance and basic function.

Compatibility overlaps with many Tamiya Mini 4WD mounting arrangements that accept 12mm to 13mm roller bores; check track of the mounting posts, spacer clearance and screw types before fitting. These rollers can be paired with sealed or open bearings depending on the axle and shaft hardware you use. Note that the component is an accessory for scale Mini 4WD cars rather than a complete kit.

Installation considerations include shaft diameter tolerance, spacer thickness to avoid contact with bodywork, and the choice of screw or locknut when securing rollers to stay mounts. Because the parts are aluminum, inspect mating surfaces and bearings for fretting if you use hardened shafts or steel spacers. Routine cleaning of anodized surfaces with a soft brush will keep the finish presentable for display or storage.

For collectors, the anodized pink finish provides a consistent aesthetic when mixed with other aluminium accessories. For builders, confirm bearing type and shaft fit before purchase to avoid last-minute fitting work. This roller set is a straightforward spare part intended to replace worn plastic rollers or to match aluminium upgrade sets already in a build.
