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

Introduction to the 19mm Mini 4WD rollers

The Tamiya Mini 4WD 19mm Aluminum Ball Race Rollers in light blue are designed to refine handling and stability on circuit layouts. Their lightweight, ringless build reduces rotating mass while offering reliable performance in regular racing scenarios.

Materials and function

These 19mm aluminium ball rollers forgo external rings to cut weight and lower inertia. The light blue finish is both tidy and functional. They help guide the car through corners with less side impact and better predictability.

Fitment and everyday use

Compatible with MS, MA, AR and VS chassis types, these rollers install in place of standard parts and provide an easy performance upgrade. They suit both high speed straights and tighter technical sections of a course.

Race day impact

Lower rotating mass assists acceleration and aids speed retention between corners, giving a steadier lap pace. Reduced friction and improved tracking help maintain consistent lap times under varying conditions.
