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

Overview of the Mini 4WD 19mm rollers

The Tamiya Mini 4WD 19mm Aluminum Ball Race Rollers in light blue provide a low-mass option to tighten handling on varied track layouts. Their ringless construction keeps the part light while remaining resilient under race conditions.

Build and role on the car

These 19mm aluminium ball rollers omit external rings to cut weight and reduce inertia. The light blue colouring makes for a tidy visual upgrade, while the rollers help the car track more predictably through bends.

Compatibility notes

Designed to suit popular Mini 4WD chassis like MS, MA, AR and VS, these rollers mount in place of stock units without complex changes. They are well suited to both high speed circuits and tight technical courses.

Performance benefits

The lighter rotating mass aids quicker acceleration and better top speed carry, particularly on runs with many turns. Less friction and improved guidance through corners give a cleaner lap profile.
