Tamiya 3RACING M4WD-32/PK 19mm Pink Aluminium Ringless Rollers  [M4WD-32/PK]

19mm roller features and benefits

The Tamiya Mini 4WD 19mm Aluminium Ball Race Rollers by 3Racing are precision components aimed at improving line stability for Mini 4WD cars. These ringless rollers are finished in pink and designed to reduce lateral play while offering smooth rotation through turns.

Fitment and how they function

These aluminium ball race rollers are suitable for several Tamiya Mini 4WD chassis styles, notably MS, MA, AR and VS. The ball race assembly lets the roller spin freely under load, which helps the car hold a cleaner trajectory around bends.

On-track impact

Fitting 19mm rollers can produce more consistent lap times thanks to improved contact handling and reduced unwanted movement. The aluminium construction balances lightweight performance with resistance to wear from repeated track use.
