The Traxxas 8964G Aluminum Shock Caps are replacement or upgrade components designed for Traxxas vehicles with oil-filled shocks, including models like the Traxxas X-Maxx and Traxxas Maxx. Made from anodized aluminum, these shock caps provide a durable and precise seal for the shock bodies, helping maintain consistent damping performance and preventing oil leaks. Manufactured by Traxxas, they are fully compatible with the corresponding shocks, making them an ideal choice for replacing worn or damaged caps or for upgrading the appearance of the vehicle.
