2005-2024 Superduty Front 2.5 Dual Rate Spring Kit (ICO62510)

The ICON Vehicle Dynamics 2.5-inch Front Dual Rate Spring Kit is a premier suspension upgrade for the 2005-2025 Ford F-250 and F-350 Super Duty 4WD. These springs are engineered to provide a level stance and significant improvements in ride quality across all types of terrain. Unlike standard linear springs, ICON’s dual-rate design features two distinct spring rates: a softer initial rate for soaking up small road chatter and a firmer secondary rate that engages during deeper compression to prevent bottoming out and improve stability when off-roading or hauling heavy loads.

Features

• 2.5-Inch Lift Height: Levels the front of the truck with the rear, providing a more aggressive stance and clearance for up to 35-inch tires.
• Dual Rate Design: Delivers a "best of both worlds" ride, plush and comfortable on the highway, yet firm and controlled when the suspension is pushed to its limits.
• Shot-Peened & Pre-Set: Undergoes a rigorous manufacturing process to increase tensile strength and ensure the springs will never sag or break over time.
• Caster Correction Cams: Includes application-specific alignment cams to restore proper front-end caster geometry, ensuring excellent straight-line tracking and steering feel.
• Corrosion Resistant: Finished in a high-quality, dual-stage semi-gloss black powder coat to withstand harsh road salts and environmental debris.
• Bolt-On Installation: Designed as a direct replacement for the factory coil springs with no cutting or welding required.

Notes

• Specifically fits 2005-2025 Ford F-250 and F-350 Super Duty 4WD models.
• Note for 2020-2025 Models: Due to a lower factory ride height on newer Super Duty trucks, these springs may provide closer to 3-3.5 inches of lift compared to older models.
• Models equipped with the Tremor package will see approximately 1.5 inches of lift over their factory height.
• Optimized for trucks equipped with Diesel engines (Gas-specific versions are available for lighter front-end weights).
• For 2005-2016 F-250 models, a 4-inch rear block kit is recommended to achieve a perfectly level stance.
