Mini 4WD 4mm Hex Post Upgrade for Roller Brackets M4WD-02/GO by 3Racing  [M4WD-02/GO]

Gold 4mm hex posts M4WD-02/GO for precise roller mounting

These 4mm hex posts provide a compact mounting option for securing rollers and brackets on Mini 4WD chassis. Aimed at experienced modders, the parts maintain consistent post geometry for reliable fitment on Super-II, MA and similar performance platforms. The gold coating aids part matching and simplifies maintenance.

Installer guidance includes checking clearances, common mounting orientations, and ensuring correct thread engagement: the posts act as a rigid standoff for roller assemblies and are most often used with low-profile nuts and washers. They are well suited to workshop swaps or visual matching where uniform post height and hex engagement are important.

Compatibility is primarily with standard Tamiya Mini 4WD components accepting 4mm hex posts. This is an aftermarket spare and does not change wheel, motor, or drivetrain specifications. Confirm fit on your specific roller bracket and body mounts before permanent fitting.
