Tamiya 3RACING M4WD-34/LB 12-13mm Light Blue Double Aluminum Rollers  [M4WD-34/LB]

Quick look at the Tamiya Mini 4WD double aluminium rollers (12-13mm)

The Tamiya Mini 4WD Double Aluminum Rollers in light blue are made to increase stability and sharpen cornering for your Mini 4WD car. As a straightforward upgrade, they help racers who want cleaner lines and fewer derailments during laps.

Design and chassis fit

These double rollers are compatible with common Tamiya Mini 4WD platforms such as MS, MA, AR, and VS. Their aluminium build gives added rigidity so the rollers keep a steady contact patch while negotiating high speed corners.

Track performance benefits

Compared with basic plastic rollers, aluminium variants reduce flex and friction at the contact points, smoothing transitions through curves. That makes them a useful part for tuning handling on official track layouts and club races.

Installation tips

Fitting is straightforward using the chassis roller mounts already provided on most Mini 4WD kits. No custom cutting or chassis modification is required, so both hobbyists and newcomers can fit them quickly.
