Tamiya 15426 JR 19mm Aluminum Rollers with Plastic Rings - Track Tuned Rollers  [15426]

Overview and Use

The Tamiya 15426 JR 19mm Aluminum Rollers with Plastic Rings are an upgrade aimed at improving the track behaviour of Mini 4WD cars. Their dish-shaped aluminium body offers added strength over older spoke styles while the plastic rings soften impacts against course walls.

Design Details

Constructed as dish-type aluminium rollers, these parts resist bending and provide a stable contact surface. The blue plastic rings fitted to the rollers cut friction and help maintain speed through corners.

Chassis Compatibility

These rollers are compatible with a broad range of Mini 4WD chassis, including models in the Mini 4WD PRO lineup. They are easy to integrate into common setups for fine-tuning handling characteristics.

Performance on Circuits

Replacing stock rollers with these aluminium units can reduce vibration and increase directional stability, which is especially beneficial on faster sections where precise control is essential.
