Rancho RS9000XL 0″ Rear Lift Shocks for 2017-2020 Ford F-450 2WD

Part Number: RS999046

Summary: The Rancho RS9000XL series delivers industry-leading flexibility for heavy-duty trucks, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows Ford F-450 owners to instantly transition from a soft street ride to a firm, controlled setting for heavy towing or hauling. By providing nine distinct levels of damping, these shocks solve the compromise between empty-bed comfort and loaded stability, ensuring your Super Duty remains composed under any load condition.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for towing, hauling, or daily driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road inputs to ensure consistent tire-to-road contact.
• Protective Boot: A heavy-duty liquid metallic finish and included dust boot provide a secondary layer of protection against road debris to ensure long-term seal integrity.
