Tamiya 15161 JR 17mm Aluminum 3-Spoke Ball-Race Rollers Track Kit  [15161]

Quick look at JR 3-spoke aluminium rollers

The Tamiya 15161 JR 3-Spoke Ball-Race Rollers are a practical tuning part for Mini 4WD builders aiming to tighten cornering and cut unwanted shake. These 17mm aluminium rollers give a reliable roll with less vibration on high-speed runs.

Materials and performance

Made from light aluminium with a three-spoke layout, the rollers combine strength and low weight. Rubber rings fitted to the rollers act as simple dampers, reducing chatter when the car hits rails or guard walls.

Compatibility and recommended setups

These rollers are compatible with many Tamiya Mini 4WD chassis, letting you swap them between cars as you refine setups. They suit racers who focus on consistent lap times and cleaner line holding.
