Rancho RS5000X 0.5-4″ Lift Shocks for 1981-1991 Chevy Suburban 4WD

Part Number: RS55001 / RS55112

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade over factory damping for lifted Chevy and GMC applications. Engineered with a unique valving system, these shocks mitigate harsh impacts and body roll commonly associated with larger tire fitments and increased ride heights. This set is specifically configured for vehicles with 0.5 to 4 inches of lift, ensuring the piston remains within its optimal operating range for maximum durability and smooth street comfort.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed damping to ensure controlled ride quality on uneven terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent force against the hydraulic fluid to ensure reduced aeration and shock fade during spirited driving.
• Enlarged Shock Body: A 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures and consistent performance under load.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier against road debris and moisture to ensure the longevity of the polished chrome piston rod.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically sized and valved to work with vehicles that have already been lifted 0.5″ to 4″ via leaf springs or other suspension components.

Are these shocks sold as a complete set?
Yes, this specific SKU includes a full set of four shocks (two front and two rear) tailored for the 1981-1991 Chevy Suburban and 1992-1999 GMC Yukon.

What is the benefit of the twin-tube design?
The twin-tube design is exceptionally durable for off-road use; if the outer body is dented by a rock, the inner cylinder remains unaffected, allowing the shock to continue functioning properly.
