Rancho RS9000XL 5″ Lift Shocks for 2017-2020 Ford F-250/F-350 4WD

Part Number: RS999044 / RS999036A

Summary: The Rancho RS9000XL series provides the ultimate in ride control for heavy-duty Ford trucks configured with a 5-inch lift. Featuring a signature 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to match specific towing, hauling, or off-road requirements. This Tier 2 adjustable system solves the compromise between empty-bed comfort and loaded-down stability by putting valving control directly in your hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Diameter Body: A 2.75-in. reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained heavy use.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent performance under demanding conditions.
• Protective Boot: A heavy-duty liquid metallic finish and included bellows boot provide a shield against road debris and moisture to ensure long-term seal integrity.
