Rancho RS9000XL 4″ Rear Lift Shocks for 2011-2016 Ford F-350 4WD

Part Number: RS999261

Summary: The Rancho RS9000XL series provides industry-leading adjustability for Ford F-350 owners who demand versatility from their heavy-duty suspension. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered to accommodate 4 inches of rear lift, they provide the necessary travel to maintain contact and control on uneven terrain.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for daily driving or maximum payload support.
• Large Diameter Shock Body: A 2.75-inch liquid-filled reserve tube provides increased oil capacity to ensure consistent performance by reducing internal fluid temperatures during heavy cycling.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier against oil foaming to ensure immediate damping response and reduced fade.
• Polyurethane Bushings: Heavy-duty mounting material provides enhanced durability and vibration isolation to ensure a quiet, controlled cabin environment.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual dial located at the base of the shock; simply turn the knob to position 1 for the softest ride or position 9 for the firmest setting.

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 4 inches of rear lift installed.

What is the benefit of the large 2.75-inch body?
The larger body increases oil volume, which acts as a heat sink, preventing the shock from “fading” or losing effectiveness during long periods of towing or off-road use.
