Compatible with Super-II, MA, MS, AR Double Aluminum Rollers 12-13mm M4WD-34/GO for Mini 4WD by 3Racing  [M4WD-34/GO]

Low-profile golden concentric rollers for performance chassis

These double aluminum rollers are sold as aftermarket spares for hobbyists who tune or restore Mini 4WD racers. The set is a pair of concentric rollers with a gold anodized finish, built for locations where compact, low-drag guide wheels are preferred.

This description focuses on fitment remarks, expected material performance and maintenance tips rather than assembly steps. The rollers suit Mini 4WD platforms like Super-II, MA, MS and AR; exact installation depends on your existing posts and adapter parts.

Surface treatment and material selection influence long-term wear against plastic or metal standoffs. Anodized aluminum helps resist corrosion and keeps the surface hard, but bearing seats and mating posts should be checked regularly to prevent fretting and uneven wear.

Collectors will find these rollers a neat visual spare that preserves chassis layout. Tuners can use them when experimenting with roller spacing, bearing choices or different cornering strategies on various circuit profiles.
