Summary: The Rancho RS9000XL series delivers industry-leading versatility for your GMC K1500 or Toyota Land Cruiser FJ40. Featuring a globally recognized 9-position manual tuning knob, these shocks allow you to instantly adjust your damping profile to match changing loads or terrain. Whether you are seeking firm control for towing or a soft, compliant ride for daily commuting, this nitrogen-gas pressurized solution provides the exact damping response required for 0-2 inches of rear lift.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for any environment.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in oil foaming and aeration to ensure consistent performance during heavy-duty cycles.
• Large Shock Body: An increased fluid capacity design provides superior heat dissipation to ensure fade-free operation during off-road use.
• Protective Boot: A durable poly-vinyl accordion boot provides a shield for the piston rod to ensure long-term seal integrity against trail debris.
