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

Product summary for Tamiya 15418 JR Double Aluminum Rollers

The Tamiya 15418 JR Double Aluminum Rollers offer a straightforward upgrade for Mini 4WD racers looking to tighten cornering stability. Dual-diameter rollers with rubber rings help control contact with track walls and reduce erratic rebounds.

Construction and handling traits

Precision-machined aluminum gives the rollers strength under sustained racing. The rubber on the 12mm rollers provides a controlled grip point that calms side impacts and aids line keeping through bends.

Compatibility notes

These rollers are designed to fit both Mini 4WD PRO and standard Mini 4WD platforms and are easy to retrofit into existing builds without major changes.

Why racers fit them

For courses with tight corners or rapid direction changes, the Tamiya 15418 set reduces lateral oscillation and lets drivers maintain higher average speeds with fewer corrections.
