Summary: The Rancho RS9000XL series provides a premium adjustable damping solution for heavy-duty Ford trucks. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition between a soft street ride and firm control for heavy hauling or towing. Engineered to accommodate 2.5 inches of rear lift, these shocks solve the compromise between daily comfort and work-ready stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct damping levels to ensure the perfect ride quality for varying payloads or terrain.
• Nitrogen Gas Charging: Pressurized nitrogen gas provides a consistent response by minimizing aeration and foaming to ensure stable performance during heavy cycling.
• Heavy-Duty Body: A large 2.75-inch diameter shock body provides increased fluid capacity to ensure lower operating temperatures during demanding use.
• Polyurethane Bushings: High-durability polyurethane material provides precise alignment and reduced deflection to ensure long-term service life.
