Tamiya 15525 Low Friction Dual Rollers with Rubber Rings - 13mm & 12mm, Red/Blue  [15525]

Overview for Track Use

The Tamiya 15525 Low Friction Plastic Double Rollers with Rubber Rings provide a compact dual-roller setup that improves corner stability on Mini 4WD cars. The kit combines a 13mm lower roller with a 12mm upper roller in contrasting red and blue. Constructed from low-friction POM, the small top roller is fitted with a rubber ring to steady rotation on contact.

Where They Work Best

These rollers reduce unwanted friction and help the car maintain its line through bends by supporting the chassis at two diameters. They are suitable for many Mini 4WD and Mini 4WD PRO machines, although you may need to alter bumper positions or trim bodywork for the stacked roller setup.

Practical Racing Impact

On race day the Tamiya 15525 rollers help cut speed loss in corners and limit abrupt changes in direction. Their straightforward fit makes them a useful choice for hobbyists upgrading handling without deep technical changes. The rubber ring delivers smoother interaction with track walls for steadier lap times.
