Rancho RS5000X 5-6″ Rear Lift Shocks for 1999-2004 Ford F-250 4WD

Part Number: RS55045

Summary: The Rancho RS5000X series features an innovative cross-tuned twin-tube design specifically engineered for heavy-duty applications. By utilizing a larger 2.25-inch reserve tube, these shocks provide increased fluid capacity to maintain cooler operating temperatures during demanding use. This configuration is optimized for Ford F-250/F-350 trucks with 5 to 6 inches of rear lift, delivering a refined street ride and consistent damping performance off-road.

Features

• Cross-Tuned Technology: A unique valve base system provides progressive engagement at varying speeds to ensure smooth ride quality and controlled handling.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent damping performance under load.
• 2.25-inch Reserve Tube: An oversized outer body provides increased oil capacity to ensure maximum heat dissipation during towing or hauling.
• Protective Boot: A durable polyvinyl accordion boot provides a shield for the piston rod to ensure long-term seal integrity against debris.

Why Choose This Product?

• Engineering Advantage: Rancho’s twin-tube design is purposely built with a larger bore to handle the thermal loads of heavy-duty Ford trucks without the harshness of a race-valved shock.
• Performance Benefit: Drivers experience a significant reduction in “body roll” and axle hop, resulting in a more planted feel whether the bed is empty or loaded.

Frequently Asked Questions

Will these shocks lift my Ford F-250?
No, these shocks do not create lift. They are specifically valved and sized for vehicles that already have a 5-6 inch rear lift kit installed.

Do these include the mounting hardware?
Yes, these shocks include the necessary bushings and sleeves for a direct-fit installation on the 1999-2004 Ford Super Duty platforms.

What is the benefit of the twin-tube design for my truck?
The twin-tube design is more resistant to external damage; if the outer tube is dented by a rock or debris, the inner cylinder (where the piston moves) remains unaffected, ensuring you aren’t stranded.
