Orange pivot cup. The pivot cups are the rubber components housed on the outer part of the baseplate. Like bushings, the pivot cup must be in good condition to fulfill its function, which is to assist the truck in faster and smoother self-centering. It also protects the pivot area every time you perform a trick or turn the trucks. Without it, over time, the tip of the hangar would wear down until it breaks or decreases in size, hindering the proper functioning of the truck.
