Tamiya 15251 - 19mm aluminium roller with plastic ring, off-road favourite for Mini 4WD tuning  [15251]

19mm aluminium roller Tamiya 15251 with plastic ring

The Tamiya 15251 is a 19mm aluminium roller that uses a plastic ring to cut friction and smooth contact with track rails. It is a straightforward upgrade for Mini 4WD cars that need steadier cornering and quieter operation during runs.

Why the materials matter

Aluminium gives the roller a light, rigid core while the plastic ring lowers wear and reduces vibration. That combo results in less drag through chicanes and corners, helping cars keep a better line on a variety of circuits. It is compatible with typical Tamiya Mini 4WD chassis like MS and MA with standard mounting points.

How racers use these rollers

These rollers help sustain momentum through bends and minimise derailment risk, offering a practical balance between sliding and grip. They are a popular choice for racers who want improved handling without complex setup changes.
