Rancho RS5000X 4″ Lift Shocks for 1999-2004 GMC Sierra 2500 4WD

Part Number: RS55296 / RS55297

Summary: The Rancho RS5000X series is engineered to deliver a significant upgrade in ride quality and durability for leveled or lifted heavy-duty trucks. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks provide the necessary damping control to handle the increased unsprung mass of larger tires and 4-inch lift kits. By reducing aeration and foaming, the RS5000X ensures consistent performance whether you are navigating highway commutes or rugged job sites.

Features

• Cross-Tuned Technology: A unique valve system provides a custom-tuned damping curve to ensure smooth street comfort and precise off-road control.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in fluid aeration and shock fade to ensure consistent damping during heavy-duty use.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and dent-resistant durability.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
