The Rancho RS9000XL nine-position adjustable strut for 2021–2022 Ford F-150 4WD (excluding models with continuously controlled suspension) offers manual damping adjustment across nine settings to tailor ride firmness. The strut uses an application-specific nitro-carburized piston rod, low-friction seals for fast rebound, polyurethane bushings, and nitrogen pressurization to reduce fade, making it suitable for towing, hauling, or varied on- and off-road use.
