Rancho RS9000XL 4″ Front Lift Shocks for 1997-2002 Ford Expedition 4WD

Part Number: RS999237

Summary: The Rancho RS9000XL series provides industry-leading versatility for Ford owners who demand total control over their ride quality. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your suspension damping from soft to firm. This capability ensures your vehicle is perfectly configured for daily commuting, heavy towing, or off-road excursions with a 4-inch lift height.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure the driver can optimize ride quality for various loads and terrains.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a reduced air-to-oil interface to ensure consistent performance by preventing foaming and aeration.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• 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.

• Performance Benefit: Drivers experience a significant reduction in body roll and “float” when towing, while maintaining the ability to soften the suspension for empty-bed comfort.

Frequently Asked Questions

How does the 9-position knob affect the ride?
The knob adjusts the internal valving; setting 1 offers a soft, compliant ride for highway cruising, while setting 9 provides maximum firmness for heavy towing or high-speed off-road stability.

Do these shocks provide the 4-inch lift?
No, these shocks are specifically configured for vehicles already equipped with a 4-inch suspension lift to ensure the piston operates within the correct travel range.

What is the benefit of the large 2.75-inch body?
The increased oil volume allows the shock to dissipate heat more efficiently, preventing “shock fade” during repetitive cycling or heavy-duty applications.
