Part Number: RS999043 / RS999254

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the Ford F-350 Dual Rear Wheel (DRW) platform. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to compensate for heavy towing, hauling, or empty bed highway cruising. Engineered to accommodate a 2.5-inch lift, they deliver a custom-tailored suspension response that eliminates the “one size fits all” compromise of standard shocks.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise ride control for varying load requirements.
• Large Shock Body: A 2.75-in. diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty towing.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent performance in demanding environments.
• Polyurethane Bushings: Heavy-duty polyurethane material provides enhanced durability and alignment stability to ensure long-term service life.
