Front Shock Absorber for 1999-2025 Ford F-250 Super Duty & More - Rancho RS55272

Help smooth out the ride and maintain vehicle control with the Rancho RS5000X shock absorber RS55272, a front-position damper built for on- and off-road duty. This Rancho shock absorber fits many vehicles, among them the 1999-2026 Ford F-250 Super Duty, 1999-2026 Ford F-350 Super Duty and 2000-2005 Ford Excursion, as a direct-fit replacement for the listed applications (see the "Vehicles it fits" section for the full list and engine details).

At its heart is Rancho's exclusive Cross Tuned technology — a rebound valving system paired with an advanced compression phase designed to improve overall handling and performance. Exclusive Progressive Engagement Valving is custom-tuned per vehicle to help reduce initial low-speed impacts.

• Strong and durable: 16 mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, 35 mm sintered iron piston, and a polyvinyl protective boot.
• Handles temperature extremes: large twin-tube body filled with all-weather fluid, rated to withstand internal temperatures of -40 to 248°F.
• Reduced fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing, foaming, and damping fade.
• Smoother action: polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness.
