G- Steering Stem Bearing Kit (139QMB)
Description: Steering Stem Bearing Kit for GY6 50cc 139QMB, and virtually any other scooter with these measurements. Steering head bearing set complete with bearing cups and bearings for the steering column top and bottom. Steering bearings should be replaced when a yoke is fitted or when you notice play, tightness, or knocking on the front end, during normal operation, it will result in a "floating" feel. Often the driver feels nothing of the creeping defect in stock. Only after the change, one has to carry the feeling of a completely new vehicle. Grease before mounting the bearings!
