Rancho RS5000X 4″ Lift Shocks for 2009-2013 Ford F-150 4WD

Part Number: RS55806 / RS55287

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your lifted Ford F-150. Specifically tuned for vehicles equipped with a 4-inch lift, these shocks utilize a sophisticated gas-pressurized twin-tube design to minimize fluid aeration and maintain consistent damping. This setup effectively manages the increased unsprung weight of larger wheel and tire combinations, ensuring a smooth street ride without sacrificing off-road resilience.

Features

• Cross-Tuned Technology: A unique valve system provides a progressive engagement curve to ensure balanced comfort on the highway and controlled damping on rough terrain.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term durability against rock chips and corrosion.
• Gas-Pressurization: High-pressure nitrogen charging provides a reduction in oil foaming and cavitation to ensure consistent performance during rapid suspension cycling.
• Polyurethane Bushings: High-density mounting points provide enhanced vibration isolation to ensure a quiet and comfortable cabin environment.
