The Tamiya Mini 4WD Double Aluminum Rollers in light blue are aimed at improving handling consistency and reducing drag at the rails. They are a practical upgrade for racers who want cleaner lines through corners.
These aluminium rollers are compatible with MS, MA, AR and VS Tamiya Mini 4WD chassis. The dual 16-17mm sizing lets you experiment with roll height and contact area to match different circuit demands.
Properly installed, the rollers help minimise derailment and smooth cornering at speed. They deliver noticeable gains on layouts with tight turns and rapid direction changes.
They install using common Mini 4WD fittings and require only basic tools. Inspect mounting points and bearings periodically to keep track performance reliable.
