Summary: The Rancho RS900XL series provides industry-leading versatility for the Ford F-350 Super Duty. Featuring a globally recognized 9-position manual tuning knob, these shocks allow drivers to adjust damping levels to compensate for varying payloads and terrain. Whether you are daily driving, towing a heavy trailer, or navigating off-road trails, this set is specifically configured for vehicles with a 4-inch lift to maintain optimal piston travel and ride quality.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during extreme use.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming.
• Heavy-Duty Piston: A 18mm nitro-carburized rod provides exceptional structural rigidity to ensure long-term durability under high-load applications.
