Rancho RS5000X 0-2″ Rear Lift Shocks for 1969-1991 GMC Suburban 1500 4WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for both on-road and off-road environments. Engineered with a unique valving system, these shocks mitigate the harsh impacts typical of classic 4WD leaf spring configurations. By balancing internal fluid movement with gas pressurization, these shocks deliver a smooth street feel while maintaining the durability required for light trail use.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping forces to ensure a controlled ride over varying terrain.
• Gas Pressurization: A high-pressure nitrogen charge provides a consistent damping response to ensure reduced aeration and shock fade during extended use.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and outer-shell durability to ensure internal components remain functional even if the outer body is dented.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance to ensure long-term sealing integrity in harsh environments.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and sized to accommodate vehicles already equipped with 0 to 2 inches of rear lift height.

What is the benefit of the twin-tube design for off-roading?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning.

Do these come with the boots?
Yes, these shocks include Rancho’s signature red protective boots to shield the piston rod from dirt and moisture.
