Smooth out the ride and keep your truck planted with the Rancho RS5000X Suspension Shock Absorber RS55047, a direct-fit rear damper for the 2005-2016 Ford F-350 Super Duty (see the Buyer's Guide tab for engine-level fitment). Built around Rancho's exclusive Cross Tuned technology, it pairs a tuned rebound valving system with an advanced compression phase to improve on- and off-road handling.
Custom-tuned valving: Progressive Engagement Valving is tuned for the application to help reduce initial impacts at low speeds and minimize a rough ride, while the Compression Control Valve regulates fluid transfer to help maintain shock motion control.
Strong and durable: 16mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35mm sintered iron piston and a polyvinyl protective boot.
Handles temperature swings: Large 2-1/4 inch twin-tube body filled with all-weather fluid for cooler operation, rated to withstand internal temperatures of -40 to 248°F.
Reduces fade: Nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing that causes damping fade and foaming.
A polyurethane rebound bumper, rubber bushings and fluon-banded piston further smooth the ride. Backed by Rancho's Limited Lifetime Warranty. Sold individually; replacing both rear shocks as a matched pair is recommended for balanced ride control.
