TUNE UP PARTS

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 set includes four 10mm, six 12mm, two 20mm, four 25mm and four 30mm screws, finished in a cool shade of black.

Insert it between the rear of the chassis and the motor to fix the motor more securely. Even with a strong shock such as a jump, the motor mounting part will not move, reliably transmitting power and improving the reliability of the run. Made of aluminum, which is good at transferring heat, it has a high heat dissipation effect and a vivid blue anodized color. Can be used with Zero, Super 1/FM/II/TZ/TZ-X chassis. *Cannot be used with the kit's standard motor.
