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

Part Number: RS55269

Summary: The Rancho RS5000X series leverages advanced CrossTun technology to provide a significant upgrade over factory damping for lifted applications. Engineered for durability and smooth street comfort, these twin-tube gas-pressurized shocks are specifically valved to manage the increased unsprung weight of larger tire and wheel packages. Whether navigating daily commutes or moderate trails, the RS5000X delivers a consistent, controlled ride by minimizing fluid aeration and shock fade.

Features

• CrossTun Technology: A unique progressive valving system provides increased control at high speeds while maintaining plushness at low speeds to ensure a balanced ride across varied terrain.
• Twin-Tube Design: A 2.25-inch diameter outer body provides increased oil capacity and dent resistance to ensure the internal piston remains functional even in harsh off-road environments.
• Nitrogen Gas Pressurization: A high-pressure gas charge minimizes air-to-oil mixture (foaming) to ensure consistent damping performance and rapid response times.
• Protective Boot: A durable polyvinyl accordion boot protects the polished chrome piston rod from debris and corrosion to ensure long-term seal integrity.

Why Choose This Product?

• Engineering Advantage: Rancho’s application-specific valving eliminates the “one size fits all” approach, ensuring the damping curve is tuned to the specific weight and geometry of your truck or SUV.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically lengthened and valved for vehicles that already have a 4-inch rear lift kit installed.

What is the benefit of the Twin-Tube design?
The twin-tube design is highly durable for off-roading; if the outer body is dented by a rock, the inner cylinder (where the piston moves) remains unaffected, allowing the shock to continue functioning.

Are these shocks sold as a pair?
Yes, this SKU (2xRS55269_n576) includes a pair of two (2) shocks for the rear of your vehicle.
