The 9mm aluminium ball race rollers for Mini 4WD, designed by 3Racing, are a popular upgrade for drivers wanting steadier cornering and smoother rolling behaviour. The ringless aluminium construction keeps weight down while the gold finish offers a neat aesthetic.
These rollers are compatible with most Tamiya Mini 4WD chassis, making them suitable for a wide range of builds. Without the outer ring the rollers present less rotational inertia, which helps with quicker transitions between straights and bends.
Expect improved stability through turns and more predictable exits when these aluminium rollers are fitted. For club racing and practice sessions they provide a reliable way to refine your car's balance.
