The Tamiya 94861 JR 13mm Aluminum Ringless Ball Race Rollers are a solid upgrade for Mini 4WD racers. The ringless profile reduces rubbing against track barriers, which helps maintain momentum through corners. Built from durable aluminium, these rollers are intended for regular use. They come fitted with 520 ball bearings for dependable spin, and they suit both front and rear roller applications. The purple finish gives a race-ready look without compromising function.
Compatibility covers Mini 4WD PRO and standard Mini 4WD chassis, making these rollers a flexible option for many builds. Fit them when you want a low-drag, long-lasting roller set that looks the part on race day.
