RPM designed these spring cups to help alleviate the frustrations sometimes associated with shock maintenance. Your shock springs rest in these cups at the base of the shock. Sometimes, during disassembly, stock cups get clogged with debris and become difficult to remove and clean. These cups are easy to remove, clean, and reinstall and have a better shelf for the springs to rest on. In addition, our lower spring cups are molded in a variety of colors for added personalization of your favorite ride.
