Product outline for Mini 4WD enthusiasts

These 19mm aluminum ball race rollers from 3Racing present a lightweight, ringless option for Tamiya Mini 4WD models. The pink finish makes them easy to identify while the simple design aims to reduce unnecessary weight.

Engineering and track behaviour

With attention to low friction and weight reduction, these rollers support steadier cornering and more predictable handling. The 19mm diameter is chosen to balance grip and manoeuvrability on technical circuits.

Fitment across chassis

They are compatible with popular Tamiya Mini 4WD chassis types such as MS, MA and AR, and they install using common mounting practices so they are straightforward to fit for most hobbyists.

Upgrade considerations

Adding these lightweight rollers can refine the way your car negotiates bends and transitions. For racers focused on consistent lap times, they are a useful part of a broader tuning plan including motor and gear tweaks.
