AEG Shim Set, Bushing, & Bearing

Metal bushings or bearings are one of the components that hold the gears in place inside the gearbox. You will need to change the stock plastic bushings to metal bushings after any spring upgrade. Upgrading to metal bushings or bearings will be able to support the gear shaft better as it rotates. Plastic bushings have a tenancy of wearing out after continuous rubbing on the gear shaft. Shims are one of the most important part of the whole upgrade. What are shims? Shims are the small washers that keep the spacing of the gears and the gearbox correct.
