Part Number: RS999048 / RS999045

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Ford F-250 Super Duty. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting for heavy towing or high-performance off-roading. Engineered specifically for vehicles with 5-6 inches of lift, this set provides the necessary travel and damping control to maintain stability in a heavy-duty platform.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can customize ride quality for specific loads or terrain.
• Large Shock Body: A massive 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent damping during extreme use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure immediate response and fade-free performance.
• Polyurethane Bushings: Heavy-duty polyurethane material provides enhanced durability and reduced deflection to ensure precise handling and long-term service life.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body. You can manually turn the knob to your desired setting without removing the shock from the vehicle.

Do these shocks provide the 6-inch lift for my F-250?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on Ford F-250 trucks that already have a 5 to 6-inch suspension lift installed.

What setting should I use for towing a heavy trailer?
For towing or hauling heavy loads, it is recommended to use a higher setting (typically 7-9) to increase firmness and control sway, then return to a lower setting (3-5) for empty bed comfort.
