Complete MR33 ball bearing set for the Xray XB4 2020 4WD buggy (22 ball bearings)!
Ball bearings must be replaced from time to time despite regular maintenance. The easiest way is to use a complete ball bearing set for your vehicle. The interval between a complete exchange of the bearings depends on how much you generally drive. If you use your RC car very regularly, then a change of the ball bearings is always recommended at the beginning of the indoor and outdoor season. At the latest, you completely disassemble your vehicle and rebuild it, and a fresh set of ball bearings is the best choice.
