Mini 4WD Double Roller Upgrade 12-13mm M4WD-34/GO for Super-II MA MS AR compatible chassis by 3Racing  [M4WD-34/GO]

Golden concentric rollers for compact Mini 4WD builds

This set of double aluminum rollers is offered as an aftermarket spare for hobbyists focused on performance Mini 4WD. The pair comes in a golden anodized finish and is made for positions where compact, low-resistance guide rollers are preferred on common racing frames.

The notes below highlight fitment considerations, expected behaviour of the material and routine maintenance rather than detailed assembly guidance. These rollers are compatible with Mini 4WD chassis like Super-II, MA, MS and AR; installation varies with existing posts and adapter components.

Choice of aluminum and anodizing affects wear rates and mating surface interaction. While anodizing increases surface hardness and corrosion resistance, you should still inspect bearing bores, posts and spacers to avoid uneven wear or binding. Keep proper spacer stacks to ensure free rotation and prevent contact with bodywork or guide rails.

For parts collectors these rollers match aesthetically and do not change chassis geometry. For racers and tuners they offer a compact option when testing different roller placements, bearing types or cornering setups on varied track layouts.
