Summary: The Rancho RS9000XL series provides industry-leading versatility for Ford F-350 owners who demand control over their ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to match changing loads or terrain. Whether you are daily driving unladen or hauling heavy equipment, this Tier 2 adjustable solution bridges the gap between street comfort and heavy-duty towing stability.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force to ensure the driver can optimize ride quality for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance in demanding environments.
• Polyurethane Bushings: Durable polyurethane material provides enhanced responsiveness and longevity to ensure a secure connection between the chassis and axle.
