Rancho RS5000X 4″ Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS55268

Summary: The Rancho RS5000X series utilizes an innovative Cross-Curve valving system to provide a significant upgrade in ride quality for your lifted GMC Sierra. Engineered for durability and dent resistance, these twin-tube gas-pressurized shocks are specifically configured for 4-inch lift applications. This set provides a balanced, smooth street feel while maintaining the ruggedness required for off-road environments and heavy-duty work use.

Features

• Cross-Curve Valving: A progressive multi-stage engagement provides custom internal tuning to ensure a smooth ride during daily driving and improved control during off-road maneuvers.
• Twin-Tube Gas Pressure: The 150 PSI nitrogen gas-charged design provides a consistent damping response to reduce aeration and foaming in demanding conditions.
• Heavy-Duty Construction: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures and longer service life.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are specifically sized and valved to work with a vehicle that already has a 4-inch suspension lift kit installed.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner working tube remains unaffected, ensuring you aren’t left stranded on the trail.

Does this include all four shocks?
Yes, this specific SKU includes a complete set of four shocks (two front and two rear) for a total suspension overhaul.
