Rancho RS5000X 1.5″ Rear Lift Shocks for 1963-1991 Chevy Suburban 2WD

Part Number: RS55118

Summary: The Rancho RS5000X series features a patented progressive rebound and compression disc system that significantly improves on-road handling and off-road durability. Engineered for vehicles with a 1.5-inch rear lift, these gas-pressurized shocks utilize a twin-tube design to protect internal components from trail debris and stone pecking. This setup provides a smooth, controlled ride that eliminates the harshness typically associated with lifted suspension geometries.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound discs provide a gradual transition of fluid to ensure a smooth ride over small road imperfections.
• Twin-Tube Gas Pressure: A 5/8-inch nitro-carburized piston rod provides increased structural rigidity to ensure long-term seal integrity in demanding environments.
• Dynamic Rebound Spring (DRS): An internal tuned compression control valve provides a mechanical cushion during full extension to ensure maximum comfort during aggressive suspension cycling.
• Protective Boot: A heavy-duty red polyvinyl bellows provides a physical barrier for the piston rod to ensure protection against moisture and abrasive contaminants.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles already equipped with a 1.5-inch rear lift kit.

What is the benefit of the RS5000X gas pressurization?
The low-pressure nitrogen gas charge reduces oil foaming and aeration, which prevents shock fade and maintains consistent damping performance during heavy use.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55118_n189) includes two rear shocks for a complete axle installation.
