Rancho RS5000X 0″ Rear Lift Shocks for 1999-2004 Ford F-350 4WD

Part Number: RS55254

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to significantly improve the ride quality of your Ford F-350. By incorporating a unique progressive engagement valving system, these shocks effectively manage the heavy unsprung weight of the F-350’s rear axle while maintaining smooth street comfort. Engineered for durability in work and off-road environments, they provide a robust solution for vehicles maintaining factory rear ride height.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide increased control during high-velocity impacts to ensure a smooth transition between paved roads and rough terrain.
• Gas Pressurized Twin-Tube: A 150-PSI nitrogen gas charge reduces aeration and foaming to ensure consistent damping performance under heavy loads.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term seal life in harsh environments.
• Protective Boot: An included red polyvinyl accordion boot protects the shock rod and oil seal from road debris and salt to ensure maximum component longevity.

Frequently Asked Questions

Will these shocks lift my Ford F-350?

Yes, these shocks come with the necessary bushings and protective boots for a direct-replacement installation on your F-350.
