The Tamiya 94956 JR 19mm Aluminum Ball-Race Roller in vivid orange offers a balance of strength and low weight for Mini 4WD models. Using 520-size bearings, the rollers deliver reduced drag and more consistent spin, which helps with repeatable lap times in club and event racing.
Each roller includes a rubber ring to absorb light impacts against track walls, preserving the roller surface and the car body. The high visibility orange finish also simplifies setup checks and makes it easier to spot alignment or wear issues between races.
