The Traxxas 7764A Aluminum Shock Caps are replacement or upgrade components designed for Traxxas vehicles with oil‑filled shocks, including models like the Traxxas Slash 2WD, Traxxas Rustler 2WD, and other compatible trucks. Made from anodized aluminum, these shock caps provide a durable, precise seal for the shock bodies to help maintain consistent damping performance and prevent oil leaks. Built by Traxxas, they are fully compatible with the corresponding shock assemblies, making them a reliable replacement for worn or damaged caps or an upgrade for enhanced durability and appearance.
