Rancho RS9000XL 0″ Lift Shocks for 1999-2004 Ford F-550

Part Number: RS999267

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the Ford F-550, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly transition from a soft street ride to a firm setting for heavy hauling or towing. Engineered to handle the high-stress demands of Super Duty work trucks, these shocks eliminate the compromise between comfort and load-bearing stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for varying load weights.
• Large Diameter Body: A 2.75-inch heavy-duty tube construction provides increased fluid capacity to ensure cooler operating temperatures during heavy towing.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier between the oil and gas to ensure consistent performance by preventing aeration.
• Polyurethane Bushings: High-performance bushings provide enhanced durability and responsiveness to ensure long-term stability under heavy-duty cycles.
