Soak up the bumps and keep your truck composed on and off the pavement with the Rancho RS5000X Suspension Shock Absorber (RS55316). It installs as a direct-fit rear shock for the 2015-2020 Ford F-150 — see the Buyer's Guide tab for engine-level fitment. Built around Rancho's Cross Tuned technology, it pairs an exclusive rebound valving system with an advanced compression phase for improved overall handling and performance.
- Cross Tuned technology: exclusive rebound valving and advanced compression phase are designed to 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 resists scuffs and corrosion, with double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
- Extreme temperatures: large 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, cutting damping fade and foaming.
