Tamiya 3RACING M4WD-40/LB 19mm Lightweight Aluminium Ball Race Rollers Light Blue  [M4WD-40/LB]

Product summary for Tamiya 19mm rollers

These Tamiya Mini 4WD 19mm Aluminum Ball Race Rollers in light blue are a straightforward upgrade to sharpen handling. The low-weight, ringless design reduces rotating mass while maintaining a compact, durable profile for racing use.

Design details

The 19mm aluminium rollers are ringless to lower weight and rotational resistance. The light blue finish offers a neat look. Their key role is to stabilise lines through corners and reduce side-to-side wobble.

Where they fit

They suit popular Mini 4WD platforms including MS, MA, AR and VS and are simple to install as a replacement for stock rollers. They perform well across both fast and technical track features.

Track advantages

The reduced mass improves acceleration and helps maintain speed through sequences. By minimising drag and improving corner control, these rollers contribute to more consistent performance lap after lap.
