Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications. Featuring a 9-position manual adjustment knob, these shocks allow owners to instantly tune damping levels to compensate for varying payloads or terrain. Whether you are seeking firm control for towing or a softer ride for empty-bed highway cruising, this Tier 2 adjustable shock delivers professional-grade ride control for your lifted Ford F-250.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the vehicle is perfectly tuned for street, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy hauling.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent damping performance.
• Heavy-Duty Piston: A 35mm sintered iron piston provides structural integrity and increased surface area to ensure precise valving response.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body; simply turn the dial to your desired setting.

Will these shocks provide my truck with a 4-inch lift?
No, these shocks do not create lift. They are specifically valved and sized to function on a vehicle that already has a 4-inch suspension lift installed.

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively, which prevents “shock fade” during long periods of towing or off-road use.
