Rancho RS9000XL 0″ Lift Shocks for 2007-2016 Ford F-550 Cab & Chassis

Part Number: RS999042 / RS999116

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Ford F-550 Cab & Chassis, featuring a globally recognized 9-position manual adjustment knob. This system allows owners to instantly transition from a refined street ride to a firm, controlled setting for heavy hauling or towing. Engineered to thrive under high-GVWR conditions, these shocks provide a custom-tuned damping solution that compensates for varying payload weights and road environments.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect balance between comfort and control for any load.
• Large Diameter Body: A 2.75-in. shock body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming in demanding conditions.
• Liquid Metallic Finish: A premium zinc-plated finish provides superior corrosion resistance to ensure long-term durability in harsh undercar environments.
