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

Part Number: RS55120

Summary: The Rancho RS5000X series provides a sophisticated upgrade for your classic Chevy Suburban 2WD, delivering a balance of rugged durability and refined street comfort. Engineered with a unique cross-tuned valve system, these shocks effectively manage the increased mass of oversized tires and 1.5-inch lift heights. By utilizing a gas-pressurized twin-tube design, they minimize aeration and shock fade, ensuring consistent damping performance whether you are cruising the highway or navigating uneven terrain.

Features

• Cross-Tuned Technology: A specialized progressive engagement valve system provides a smooth ride during initial travel while increasing control during aggressive maneuvers to ensure stability on varying road surfaces.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent oil-to-gas interface to ensure reduced aeration and improved response times.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and dent resistance to ensure long-term durability in harsh environments.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the internal seals remain free of debris and contaminants.
