Part Number: RS55126

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your Ford F-450 Super Duty. By incorporating a unique progressive engagement valving system, these shocks minimize harshness during initial impacts while maintaining firm control during heavy hauling. This setup provides a versatile solution for drivers who require durability for work-site conditions without sacrificing street comfort during daily commutes.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control during high-velocity impacts to ensure a smoother ride on uneven terrain.
• Gas Pressurization: 150 PSI nitrogen gas charging provides a consistent damping force to ensure reduced aeration and shock fade.
• Twin-Tube Body: A 2.25-inch reserve tube provides extra fluid capacity and physical protection to ensure internal components remain functional even if the outer shell is dented.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
