Tamiya Mini 4WD 19mm Lightweight Aluminum Ball Race Rollers - Red - Lightweight Corner Upgrade  [M4WD-40/RE]

Compact 19mm Tamiya Ball Rollers in Red

The Tamiya Mini 4WD 19mm Aluminum Ball Race Rollers are an essential upgrade for racers who want crisper cornering and reliable roll along the walls. These ringless, lightweight rollers are machined from durable aluminium to offer smooth rotation and steady guidance on a variety of track layouts. The bright red finish improves visibility during fast runs and helps you spot contact points at a glance.

How They Help Handling

The 19mm aluminium ball rollers cut friction at the contact points and stabilise the car through bends, letting you carry more speed out of corners. Their low mass limits added weight so the chassis stays responsive while improving directional control.

Fitment and Practical Notes

These rollers fit most common Tamiya Mini 4WD chassis configurations, making them a flexible choice whether you run MS, MA, or AR platforms. Installation is straightforward using standard roller spacers and screws; racers should check race class rules before use.
