Performance Blue Rollers for Mini 4WD - Tamiya 94979

The Tamiya 94979 JR Lightweight Double Aluminum Rollers (13-12mm) give Mini 4WD rigs a lightweight, durable upgrade. At nearly 20% less weight than conventional aluminum rollers, they cut down on unsprung rotating mass to help maintain speed through chicanes and sweeping bends. The blue anodised finish stands up to repeated contact while keeping a clean look on show-day. Using 520 ball bearings, these rollers provide reliable rotation and help stabilise cornering. They are suitable for both Mini 4WD and Mini 4WD PRO platforms, offering a straightforward tuning path for racers and hobby builders.
