Tamiya 15161 JR 17mm Aluminum 3-Spoke Ball-Race Rollers Precision Set  [15161]

Overview of JR 3-spoke roller upgrade

The Tamiya 15161 JR 3-Spoke Ball-Race Rollers are a useful parts upgrade for Mini 4WD tuners who want steadier handling through turns. These 17mm aluminium rollers are intended to provide consistent roll and improved control at race pace.

Design focus and benefits

The three-spoke aluminium construction keeps the component light yet robust, reducing unnecessary mass. Fitted rubber rings act as micro dampers, cutting vibration and helping the chassis track reliably when negotiating corners.

Versatility and track use

These rollers fit many Tamiya Mini 4WD chassis, offering flexibility for different car setups. They are particularly handy when dialing in cornering performance for tighter circuits or event tracks.
