Tamiya Mini 4WD Ringless 19mm Pink Aluminum Rollers 3RACING M4WD-40/PK  [M4WD-40/PK]

Quick intro to 19mm ringless rollers

3Racing's 19mm aluminum ball race rollers bring a lightweight option to Tamiya Mini 4WD setups without extra ring parts. The pink finish is easy to spot on the bench and the simple design focuses on lower mass and reliable rotation.

Design aims and on-track effect

These rollers minimise friction to help your car hold lines through corners. The 19mm size provides a useful compromise between roll stability and nimbleness, helping when tracks demand quick direction changes.

Which chassis will they work with

The rollers are compatible with many Tamiya Mini 4WD platforms, such as MS, MA and AR chassis. They slot into common roller mounts and can be fitted with basic hand tools by most hobbyists.

When to choose these rollers

If you want to shave small amounts of rotational mass and improve corner flow, these rollers make a sensible upgrade alongside motor and gearing tweaks. They suit racers focusing on handling refinement.
