Rollers on Mini 4WD vehicles are an optional upgrade part for any Mini 4WD race car. Tamiya Mini 4WD kits come standard with plastic rollers that usually measure 13mm or smaller. By adding larger 19mm rollers your vehicle will have a wider stance, thereby maintaining greater speed around high speed turns, while bouncing less off the walled circuit.

These lightweight aluminum roller parts have a weight reduction of around 30% over standard aluminum rollers thanks to their shape and holes, allowing speedy performance! Inbuilt 520 size bearings provide smooth movement. These rollers can be used in the front or rear of any Mini 4WD machine.

★This lightweight, 1.5mm thickness carbon fiber stay has holes for attachment of 9mm, 13mm or 19mm rollers in a wide position.

★The carbon fiber pattern will add some style to your car, as will the blue-green printed detailing including Tamiya and J-Cup logos.

★A plethora of holes ensures numerous setup options are at your disposal.
