Rancho RS90000XL 2.5″ Rear Lift Shocks for 2017-2025 Ford F-250/F-350 4WD

Part Number: RS999047

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty Ford trucks through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road excursions. Engineered to accommodate 2.5 inches of rear lift, they provide the necessary travel and control to maintain stability under varying load conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect balance between comfort and control for any terrain or payload.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance during high-demand hauling.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• 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.

Frequently Asked Questions

How do I adjust the settings on 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 firmness level—lower numbers for comfort, higher numbers for towing.

Will these shocks lift my Ford F-250?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been equipped with a 2.5-inch rear lift kit.

Can these be used on a Dually (DRW) or Chassis Cab?
No, these specific units are engineered for Single Rear Wheel (SRW) pickup models and are not compatible with Chassis Cab configurations.
