ICON Vehicle Dynamics 2005-2010 Ford F-250/F-350 4-5.5 Inch Lift Stage 1 Coilover Conversion System

The ICON Vehicle Dynamics Stage 1 Coilover Conversion System is a bolt-in front and rear suspension upgrade for 2005–2010 Ford F-250 and F-350 4WD trucks, delivering 4 to 5.5 inches of adjustable lift with improved on- and off-road ride dynamics over the factory suspension. Springs in this system are rated for diesel-engine applications only.

Height Adjustability Without Compromise

The front coilover conversion mounts directly in the OEM coil bucket location, eliminating the guesswork of fixed-height lift kits. Ride height is tunable across the full 4 to 5.5 inch range, so the truck can be set for daily highway use or dialed up for trail clearance without swapping components. Coilover heights stated in the specifications reflect a stock-equipped vehicle as the baseline.

Rebuildable Shocks Built for the Long Haul

The front coilover shock body is CAD-plated for corrosion resistance and uses a 7/8 inch shaft. Rear shocks are ICON's 2.0 VS Series, fully serviceable units. All shocks in the system are rebuildable and revalveable: worn internals can be refreshed rather than replaced outright, a meaningful cost advantage over non-serviceable alternatives on a truck that sees regular off-road use. The coilover conversion design also allows for the addition of a secondary shock at the front when greater damping is needed.

System-Level Engineering, Not Piecemeal Parts

The kit pairs the front coilover conversion with an adjustable track bar using FK rod end bearings for reduced deflection and extended service life, a radius arm drop kit to maintain correct front suspension geometry at lift height, a 5 inch rear block kit, and a rear U-bolt kit. Eibach coil springs are included and are guaranteed against sagging or breakage for life. Vehicle-specific shock valving is calibrated for the F-250/F-350 platform rather than adapted from a generic tune.

Features

• Bolt-in front fitment: installs in the OEM coil bucket location; coil centering cup removal required
• 4 to 5.5 inch adjustable lift: end-user ride height adjustable across the full range
• Eibach coil springs: lifetime guarantee against sagging or breakage; rated for diesel engines only
• Rebuildable and revalveable shocks: front 2.5 VS coilover and rear 2.0 VS shocks are fully serviceable
• FK rod end bearings: on the adjustable track bar for extended longevity and minimal deflection
• Secondary shock capability: coilover conversion allows addition of a front secondary shock

Specifications

Who This Is For and Isn't

This system suits owners of 2005–2010 Ford F-250 or F-350 4WD trucks with diesel engines who want a height-adjustable lift in the 4 to 5.5 inch range with improved on- and off-road ride quality and the ability to run OEM or recommended aftermarket wheels and tires up to 35 inches without body modification.

This system is not compatible with gasoline-engine F-250/F-350 applications: the included Eibach springs are rated for diesel engines only. It does not fit 2WD variants, and tires larger than 35x12.50 inches will require fender trimming and additional modifications not included in this kit. Installation requires removal of the coil centering cup in the factory coil bucket.

Common Questions

Will this system work with a gasoline-engine F-250 or F-350?

The ICON Stage 1 Coilover Conversion System for 2005–2010 Ford F-250/F-350 includes Eibach coil springs rated for diesel engines only. The system is not specified for gasoline-engine applications; a different spring rate would be required for a gas-powered truck.

Does installation require any cutting or modification to the factory coil bucket?

No cutting is required, but the coil centering cup inside the factory coil bucket must be removed before the front coilover conversion can be installed. Beyond that, the front unit is designed to bolt into the OEM coil bucket location without further modification to the bucket itself.

Can I run 37 inch tires with this system?

The ICON Stage 1 system is validated for tires up to 35x12.50 inches without body modification. Larger tires, including 37 inch fitments, may physically clear but will require fender trimming and additional modifications that are not part of this kit and are the installer's responsibility.

Are the shocks rebuildable, or do they need to be replaced when worn?

The front 2.5 VS coilover and the rear 2.0 VS shocks included in this Stage 1 Coilover Conversion System are fully rebuildable and revalveable. Worn internals can be serviced rather than requiring full shock replacement, which reduces long-term ownership cost on a truck used regularly off-road.

What is included in the kit?

The Stage 1 system for 2005–2010 Ford F-250/F-350 includes a front 4.5 inch box kit, a front 2.5 VS rear bolt-in coilover conversion kit, an adjustable track bar with FK rod end, a radius arm drop kit, a 5 inch rear block kit, a rear 17 inch U-bolt kit, and two rear 2.0 VS shocks. The system ships in multiple boxes.
