Tamiya 3RACING M4WD-32/LB 19mm Light Blue Aluminium Rollers  [M4WD-32/LB]

Introduction to the Tamiya 19mm rollers

The Tamiya Mini 4WD 19mm Aluminum Ball-Race Rollers in light blue offer a straightforward upgrade to help stabilise your Mini 4WD through complex sections. Supplied under the 3Racing label as 3RACING M4WD-32/LB, the ringless construction lowers bearing contact and reduces drag.

Function and chassis compatibility

These 19mm rollers fit a broad range of Mini 4WD chassis including MS, MA, AR and VS types and are simple to integrate into standard mounting points. The ball-race, ringless layout provides freer spin which smooths transitions over guide rails and through corners.

Practical benefits on lap times

In practice the lightweight aluminium body and efficient bearings help the car hold a steadier line and resist unwanted wobble. For racers focused on consistency, these ball-race rollers can deliver improved control and tighter lap performance.
