ICON 2.5 Series 7-Inch Stage 5 Suspension Kit for 2008–2010 Ford F-250/F-350 — Complete Off-Road Upgrade with Radius Arms

• Custom dual-rate coil specifications paired with 2.5-inch external aluminum reservoirs deliver progressive valving that absorbs high-speed washboard impacts without compromising tow stability under max payload weights.
• Built with twin-bypass internal piston valves and corrosion-resistant electrocoat finishes to shed heat rapidly and resist flaking from stone chips, trail abrasion, and coastal salt exposure.
• Precision-calculated kinematics preserve factory steering knuckle arc and suspension geometries, eliminating bump steer and reducing early-age wear on CV axles during steep articulation maneuvers.
• Gauge-specific clearance supports up to 39 x 13.50-inch all-terrain and mud-terrain tires with minimal fender liner trimming, maintaining safe ground clearance without requiring extended brake line routing.
• Provides a fully bolted installation path using the included extended radius arms, reinforced track bar brackets, matched sway bar end links, and pre-lubricated polyurethane bushings to replace weak OEM stress zones.
• Designed exclusively for 2008 through 2010 4WD gasoline Super Duty platforms; explicitly incompatible with chassis-cab trucks, crew-cab-only restrictions, and post-2010 frame re-engineering due to differing spring seat heights.
• Backed by ICON Vehicle Dynamics lifetime warranty against cosmetic finish defects, protecting your investment across decades of weekend overlanding or heavy-duty work truck service.
