Rancho Suspension Shock Absorber P/N:RS55287

Keep your truck composed on and off road with the Rancho RS5000X Suspension Shock Absorber (RS55287) — a rear Rancho shock absorber engineered around the brand's exclusive Cross Tuned technology. It installs as a direct-fit replacement for the 2004-2019 and 2021-2025 Ford F-150 and the 2006-2008 Lincoln Mark LT; see the Buyer's Guide tab to confirm your exact trim and engine.

• Cross Tuned technology: an exclusive rebound valving system plus an advanced compression phase to improve overall 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, durable build: a 16 mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35 mm sintered iron piston, and a polyvinyl protective boot.
• Twin-tube design: a large twin-tube body filled with all-weather fluid runs cooler and is nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing and reduce damping fade and foaming.

A polyurethane rebound bumper and rubber bushings help absorb ride harshness, while a fluon-banded piston and a low-friction, self-lubricating seal support responsiveness and quicker rebound. The Compression Control Valve is custom-tuned to regulate fluid transfer. This is a rear shock; for balanced damping, replace both sides as a matched pair. Backed by Rancho's Limited Lifetime Warranty.
