Rancho RS5000X 0″ Lift Shocks for 2005-2016 Ford F-250 4WD

Part Number: RS55042

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your Ford F-250. Engineered with a unique progressive engagement valving system, these shocks provide a smooth street feel while maintaining the durability required for heavy-duty work. This complete set is configured for vehicles at factory height (0″ lift), offering a significant upgrade over stock dampers by reducing harshness and improving chassis control under load.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased damping control as velocity increases to ensure a consistent ride on varying road surfaces.
• Gas Pressurized Twin-Tube: Low-pressure nitrogen gas charge reduces aeration and foaming to ensure fade-free performance during extended towing or hauling.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term seal life.
• Protective Boot: Included poly-vinyl accordion boots provide a physical barrier against road debris and moisture to ensure the chrome rod remains free of pits and corrosion.
