RS9000XL Strut

The RANCHO RS9000XL Strut is a premium monotube suspension upgrade designed for Ford fullsize trucks from 2014 to 2020, delivering both on-road comfort and off-road capability. As an experienced mechanic, you'll recognize this as a serious step up from factory suspension—built for drivers who demand adjustability without sacrificing reliability or ride quality. Whether you're hauling heavy loads, towing, or exploring rough terrain, the RS9000XL transforms how your truck handles dynamic driving conditions.

At the heart of the RS9000XL is RANCHO's proven Tritube monotube design, which combines a main pressure tube with dual auxiliary chambers for superior damping control and heat dissipation. The nine-way adjustable valving gives you precise tuning across compression and rebound settings—allowing you to dial in stiffness for empty cruising or firm control under load. The steel construction with silver paint finish resists corrosion and maintains structural integrity through years of demanding use, while the compact 28.25-inch length ensures proper installation geometry on modern fullsize trucks without modification to mounting points.

This strut excels for truck owners running aftermarket wheels, lifted suspensions, or increased payload—situations where factory dampers fade and bottoming becomes an issue. Installation is straightforward for any technician familiar with strut replacement; each unit ships individually (you'll need one per wheel position). The nine-way adjustment range means you won't outgrow this suspension as your truck's role evolves, making it an investment that adapts to changing needs and driving styles.
