Blue Lower Spring Cups (4) (RPM73155)

Blue lower spring cups (4-pack) are replacement parts for RC shock systems, designed to hold the base of the shock spring in place more securely than stock cups.

Made from a durable material that resists grime and cleans easily, these blue cups fit Traxxas, Losi, and Associated vehicles and work with compatible spring clips to add color to the suspension. The blue hue coordinates with RPM team colors, giving a finished, coordinated look to a complete suspension setup.
