Rancho RS5000X 2.5-4″ Lift Shocks for 1992-1998 Chevy Suburban 2500 4WD

Part Number: RS55001 / RS55227

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your lifted Chevy Suburban or GMC Yukon. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks effectively manage the increased unsprung weight of larger wheel and tire combinations. This complete set is specifically valved to accommodate 2.5-4 inches of suspension lift, ensuring your heavy-duty SUV maintains composure during both highway transit and off-road excursions.

Features

• Cross-Tuned Technology: A unique progressive engagement valving system provides a smooth initial response to small road imperfections to ensure consistent comfort on paved surfaces.
• Twin-Tube Gas Pressure: The 150 PSI nitrogen gas charge reduces aeration and shock fade to provide reliable damping force during high-intensity cycles.
• Protective Boot: A heavy-duty red polyvinyl accordion boot protects the piston rod from debris and rock chips to ensure long-term seal integrity.
• Glass-Filled Fluon Piston Seal: The specialized PTFE-based seal provides a low-friction interface between the piston and pressure tube to ensure a faster response to terrain changes.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are extended-length dampers configured for vehicles already equipped with a 2.5-inch to 4-inch suspension lift kit.

What is the benefit of the twin-tube design?
The twin-tube design offers excellent durability; if the outer body is dented by a rock or debris, the inner pressure tube remains functional, allowing the shock to continue operating.

Are the boots required for installation?
While the shocks will function without them, we highly recommend installing the included boots to protect the shafts from pitting and extend the life of the seals.
