Tamiya 15418 JR Double Aluminum Rollers with Rubber Rings (13-12mm) - Stability Upgrade  [15418]

Quick look at Tamiya 15418 JR Double Aluminum Rollers

The Tamiya 15418 JR Double Aluminum Rollers bring a practical stability upgrade to Mini 4WD setups. The paired 13mm and 12mm rollers include rubber rings that help reduce slippage on track walls and keep the car tracking through tight corners.

Build quality and roller behaviour

Made from lightweight aluminum, these rollers are built to take regular racing use. The rubber rings on the smaller 12mm rollers add a subtle braking effect that controls lateral movement without overly slowing the car.

Fits these chassis types

These rollers are compatible with Mini 4WD PRO and standard Mini 4WD machines and install with common roller mounts, making them straightforward to add to most race cars.

On-track benefits

On courses with sharp turns or complex chicanes, the Tamiya 15418 rollers reduce side-to-side bounce and let drivers carry speed more consistently through corners, helping to shave lap time with cleaner lines.
