Front Shock Absorber for 2005-2025 Ford F-250 Super Duty & More - Rancho RS55043

Smooth out the ride and keep your truck planted with the Rancho RS5000X Suspension Shock Absorber (RS55043), a front-position Rancho shock absorber that drops in as a direct-fit replacement for the 2005-2025 Ford F-250 Super Duty and 2005-2025 Ford F-350 Super Duty. Built around Rancho's exclusive Cross Tuned technology, this Rancho absorber pairs a rebound valving system with an advanced compression phase to improve overall on- and off-road handling and performance.

• Cross Tuned technology: exclusive rebound valving system and advanced compression phase improve handling and performance on and off road.
• Progressive Engagement Valving: custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimize a rough ride.
• Strong and durable: 16mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, 35mm 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.

Nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce damping fade and foaming, while a low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression. Sold individually; for even, balanced handling, replace both shocks on the axle as a matched pair. Backed by Rancho's Limited Lifetime Warranty.
