The Rancho RS9000XL rear shock for Ford F‑250 Super Duty (2017–2019) is engineered for heavy‑duty applications like towing and hauling. As a member of the RS9000XL family it provides nine‑position adjustable damping, tri‑tube all‑weather fluid construction and a nitro‑carburized piston rod for strength. Low‑friction seals and 120 PSI nitrogen charging reduce air‑to‑oil mixing and damping fade, helping maintain consistent control under load.
