Rancho RS5000X 1-2.5″ Rear Lift Shocks for 1988-1999 Chevy K1500 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series redefines the entry-level shock absorber by utilizing a sophisticated twin-tube design that balances off-road durability with on-road refinement. Engineered for the 1988-1999 Chevy K1500 and GMC Yukon, these shocks feature a cross-tuned valve system that effectively manages impact energy at various speeds. This configuration is specifically valved to handle rear lift heights of 1 to 2.5 inches, ensuring the vehicle remains composed under load or while navigating uneven terrain.

Features

• Cross-Tuned Technology: A unique progressive engagement valving system provides a custom-tuned ride to ensure consistent control regardless of terrain velocity.
• Gas Pressurized Twin-Tube: The nitrogen-charged twin-tube body provides reduced aeration and foaming to ensure fade-free performance during extended cycling.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity and corrosion resistance to ensure long-term seal integrity.
• Protective Boot: The included polyvinyl accordion boot provides a physical barrier against debris to ensure the main seal and piston rod remain free of contaminants.
