This product is a hardened steel shock shaft designed to serve as a durable pivot and sliding surface within the shock absorbers of compatible RC vehicles. The precision‑machined shaft resists bending and wear under demanding off‑road driving, helping maintain smooth damping and consistent suspension performance. It is intended for use with Traxxas XRT shock assemblies and works with the existing shock bodies and internal components for proper fit and function. RC car compatibility includes Traxxas XRT models that use the same shock system, and it serves as a direct replacement or upgrade to restore reliable suspension operation and long‑term durability.
