The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers in gold provide a subtle but effective upgrade to your car's rolling components. The absence of outer rings lowers rotating weight while preserving bearing action for smooth runs.
These 17mm rollers reduce side friction and help maintain speed through bends, letting the chassis carry momentum out of turns more reliably. The ringless profile aids rapid direction changes without adding unnecessary bulk.
These rollers fit a wide selection of Tamiya Mini 4WD mounts and are suitable for both weekend club racers and tune-up projects. Regular checks and light lubrication will keep them performing at their best.
