Rancho RS9000XL 2.5″ Rear Lift Shocks for 2017-2025 Ford F-350 4WD

Part Number: RS999047

Summary: The Rancho RS9000XL series provides industry-leading versatility for the Ford F-350, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable technology allows drivers to instantly tune damping profiles to compensate for varying payloads or terrain transitions. Whether you are daily driving unloaded or towing a heavy gooseneck, these shocks provide the specific compression and rebound control needed to maintain vehicle stability and ride quality.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier against oil foaming to ensure consistent damping performance under rapid cycling.
• Heavy-Duty Nitro-Carburized Rod: A 18mm diameter piston rod provides exceptional structural rigidity to ensure long-term durability in harsh environments.

Why Choose This Product?

• Engineering Advantage: Unlike “one-size-fits-all” shocks, the RS9000XL allows the user to mechanically override the valving to match the exact spring rate and load of the truck.
• Performance Benefit: Eliminates the “stiff” ride of empty heavy-duty trucks while providing the necessary firmness to stop trailer sway and rear-end sag when loaded.
