This is the RPM Blue Lower Spring Cup Set for 1/10 scale HPI and Associated Shocks. RPM spring cups add color to your suspension while improving the spring contact area at the base of your shocks. These cups are easy to remove, clean, and reinstall and have a better shoulder for the springs to rest on. The set comes with 4 spring cups, enough to completely cover all four corners of your vehicle!
NOTE: These do not fit the HPI Savage or Associated MGT vehicles
