Rancho RS90000XL 0″ Rear Lift Shocks for 1999-2004 Ford F-250 4WD

Part Number: RS999273

Summary: The Rancho RS9000XL series provides industry-leading adjustability for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition from a soft street ride to a firm setting for heavy towing or hauling. Engineered for the Ford F-250 and F-450, these shocks solve the compromise between empty-bed comfort and loaded-chassis control.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for varying loads or terrain.
• Large Diameter Shock Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance under rapid cycling.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
