3RACING M4WD-40/LB Tamiya Compatible 19mm Race Rollers - Race Setup Edition  [M4WD-40/LB]

Technical overview for 3RACING 19mm rollers

These 19mm aluminium ball race rollers are engineered for racers focusing on lap consistency and tuning. The ringless, low-mass configuration reduces rotational inertia while maintaining structural integrity under race loads.

Precision design and intended use

Machined aluminium construction and ball race operation provide consistent roll characteristics. The lack of an outer ring lowers weight and allows finer balance adjustments when setting front and rear roll behaviour.

Chassis compatibility and installation

Compatible with standard Mini 4WD platforms including MS, MA, AR and VS, these rollers mount as direct replacements. They are ideal for racers who want predictable handling with minimal setup changes.

Tuning and performance notes

Use these rollers to reduce rotational mass and improve acceleration response. Combined with suspension and gear ratio adjustments, they help refine corner entry and exit behaviour for tighter lap times.
