ICON Vehicle Dynamics Stage 5 Suspension System – 2023 Ford F-250/F-350 Super Duty 4WD Gas, 2.5-Inch Lift

Deliver factory-level ride compliance off-road with the ICON 2.5-Inch Stage 5 Suspension System engineered specifically for 2023 Ford F-250 and F-350 Super Duty Crew Cab 4WD gas models, utilizing patented external-reservoir shock architecture and field-adjustable fluid tuning capabilities.

• Model-Specific Street-to-Trail Geometry: Precision-calibrated for 2023 Ford F-250 and F-350 Super Duty Gas Crew Cab 4WD vehicles; strictly incompatible with Diesel, alternative fuel, CNG, DRW, chassis-cab, or 2024 model-year trucks.
• Patented Expansion Port Technology: Integrated adjustable shock absorbers feature ICON's unique Expansion Port, enabling users to add or remove internal fluid volume to instantly alter spring rates and valving to accommodate heavier aftermarket wheels, tires, and payload weights.
• Billet Aluminum Upper Control Arms: Upgrades factory stamped steel components with precision CNC-machined UCA assemblies that restore proper suspension geometry and caster angle, completely eliminating ball-joint binding and accelerating tie-rod wear during aggressive articulation.
• Optimized Tire Clearances: Provides enough suspension travel and clearance to run aggressive 35x12.50-inch tires with zero fabrication, while still allowing seamless upgrades to massive 37-inch off-road slicks via minimal inner fender work.
• All-Terrain Durability: Shock bodies constructed from heat-treated aerospace-grade alloys with a rugged hard-anodized coating, alongside durable EPDM rubber dust boots and sealed spherical joints, ensuring long-lasting protection against mud, abrasion, and heavy impacts.
• Factory-Like Handling Retention: The complete kit incorporates extended brake lines and precise lift spacers calibrated to prevent brake line stress or hose kinks during full droop compression, maintaining tight steering feedback and predictable handling under high speeds.
• Simplified Alignment Adjustments: Includes all necessary mounting hardware and upgraded bump stop extensions, though drivers should keep in mind that installing the system may require manual lateral axle alignment or an aftermarket adjustable track bar to correct center-line deviation.
