Rancho RS5000X 4″ Rear Lift Shocks for 1999-2004 Chevy Silverado 2500

Part Number: RS55297

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for vehicles equipped with a 4-inch rear lift. By integrating a unique progressive engagement valving system, these shocks effectively manage the increased unsprung weight of larger wheel and tire combinations. This gas-pressurized solution is engineered to deliver smooth street comfort while maintaining the durability required for off-road excursions and heavy-duty utility.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides restricted oil flow at low speeds and increased flow at higher piston speeds to ensure controlled handling across varying terrains.
• Gas Pressurization: High-pressure nitrogen gas charging provides a reduction in oil aeration and foaming to ensure consistent damping performance during repetitive cycling.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.
• Twin-Tube Body: A 2.25-inch outer tube provides increased oil capacity and physical protection for the inner working cylinder to ensure reliable performance even if the outer shell is dented.
