Ford F250 Series Super Duty Shock Absorber - Rear - Rancho - RS9000XL - '05-'16. This rear RS9000XL shock is a tunable, heavy-duty replacement designed for Ford F250 Super Duty trucks from 2005–2016, offering adjustable damping for a tailored ride whether you're towing, hauling, or heading off-road.

The RS9000XL delivers proven control with a nine-position, easy-to-adjust knob that lets you fine-tune firmness for on-road comfort or off-road responsiveness. Now in its fourth generation, this shock features integrated bottom mounts for added strength and a dual-component 2K paint finish to resist chipping. Built to handle extreme temperature swings, its application-specific tri-tube body and all-weather fluid maintain consistent performance from -40 to 248°F. Internal design elements like a low-friction, self-lubricating seal, graphite-filled fluon-banded piston and polyurethane rebound bumper help reduce fade and smooth out harshness for improved control and longevity.
