Compact overview of JR 3-spoke rollers

The Tamiya 15161 JR 3-Spoke Ball-Race Rollers are a straightforward upgrade for Mini 4WD fans after better stability and predictable handling. These 17mm aluminum rollers help deliver smoother cornering and steadier lap times in race and practice sessions.

Lightweight build and role

Built from lightweight aluminum with a three-spoke layout, the rollers balance durability with minimal added mass. Rubber rings included around the rollers act as simple shock absorption, cutting vibration and helping the car track cleaner at speed.

Fitment and on-track use

These rollers fit a wide selection of Tamiya Mini 4WD chassis, giving you flexibility across different setups. They are particularly useful for tuning corner entry and exit when running official circuits or home-made layouts.
