The Tamiya 94713 - 13mm Guide Ball Bearings set is designed to improve the rotational feel of Mini 4WD components. These bearings reduce drag on rollers and related parts, helping the car maintain speed with less power loss through bearings and axles.
Each bearing is 13mm in diameter and 3mm thick, and the set contains six bearings plus the required screws and nuts for fitting. Compatible with Mini 4WD and Mini 4WD PRO chassis, they are particularly effective in rear double roller arrangements to improve cornering stability and consistent track contact. A practical upgrade for racers seeking tidy, reliable tuning parts.
