Black Lower Spring Cups (4) (RPM73152)

Black lower spring cups come in a four-pack and replace the stock cups to secure the base of the shock spring more reliably. Made from a durable material, they resist grime and stay cleaner longer, helping maintain consistent suspension performance.

Designed for Traxxas, Losi, and ASC MGT vehicles, these cups pair with compatible spring clips to add color accents and complete a cohesive suspension setup, dressed up with RPM team colors.
