ICON Stage 2 Coilover Conversion System for 2005-2010 Ford F-250/F-350 4-5.5" Lift

The ICON Stage 2 Coilover Conversion System (K63112) is a bolt-in front and rear suspension upgrade for 2005–2010 Ford F-250 and F-350 Super Duty trucks, delivering 4–5.5 inches of adjustable ride height, increased wheel travel, and ICON's vehicle-specific shock valving. Springs in this system are rated for diesel-engine applications only. The system is available in one configuration and ships in multiple boxes at a combined weight of 190 lb.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Height Adjustability Without Compromise

The front coilovers mount directly into the OEM coil bucket location and allow the driver to dial in ride height anywhere in the 4–5.5 inch lift range without removing the suspension. That adjustability means the truck can be set lower for highway fuel economy or raised for additional ground clearance before a trail run, using the same hardware. ICON's vehicle-specific shock valving is calibrated for the F-250/F-350 platform, so ride quality at both ends of the adjustment range reflects the truck's actual weight and geometry rather than a generic tune.

Rear System Built for Durability

The rear 2.5 VS IR (Impact Extruded) shocks feature one-piece aluminum cylinders that resist corrosion and maintain a consistent finish over time. The 5-inch rear block kit and 17-inch U-bolt kit are included, along with the radius arm drop kit that keeps the front driveline geometry correct at the lifted height. Eibach coil springs carry a lifetime guarantee against sagging or breakage. FK rod end bearings on the adjustable track bar reduce deflection and extend service intervals compared to rubber bushings.

Fully Rebuildable, Field-Serviceable Design

Every shock in this system is fully rebuildable and revalveable, which matters on a truck that sees sustained off-road use. Rather than replacing a worn shock outright, the owner can send it for a rebuild or revalve to match a change in load or driving style. The coilover design also allows for the addition of a secondary shock at the front when the application calls for it, extending the system's tuning range without requiring new mounting hardware.

Features

• Bolt-in front fitment: mounts in OEM coil bucket location; coil centering cup removal required
• Adjustable ride height: 4–5.5 inch lift range, set without removing the coilover
• 2.5 VS rear shocks: one-piece impact-extruded aluminum cylinders for corrosion resistance
• Eibach coil springs: lifetime guarantee against sagging or breakage; rated for diesel engines only
• FK rod end bearings: on the adjustable track bar for reduced deflection and extended longevity
• Fully rebuildable shocks: rebuildable and revalveable; coilover accepts a secondary shock

Specifications

Who This Is For and Isn't

This system suits 2005–2010 Ford F-250 and F-350 Super Duty owners running diesel engines who want a bolt-in front and rear suspension upgrade with adjustable ride height in the 4–5.5 inch range and improved on- and off-road dynamics over stock.

The Eibach coil springs in this system are rated for diesel engines only and are not appropriate for gas-engine F-250/F-350 applications. The system does not fit F-250/F-350 model years outside the 2005–2010 range. Installation requires removal of the coil centering cup from the factory coil bucket; a vehicle in stock configuration with the cup in place cannot accept the coilover without that step.

Common Questions

Will this system work on a gas-engine F-250 or F-350?

No. The Eibach coil springs included in the ICON K63112 Stage 2 Coilover Conversion System are rated for diesel engines only. A gas-engine Super Duty requires a different spring specification and is not a compatible application for this kit.

Does installation require any modification to the factory coil bucket?

Yes. Installing the front coilovers in the ICON K63112 system requires removal of the coil centering cup from the factory coil bucket. The coilover cannot seat correctly with the cup in place, so that step must be completed before the front components can be installed.

Can OEM wheels and tires be used after installing this system?

Yes. The ICON K63112 Stage 2 system is confirmed compatible with OEM wheels and tires on the 2005–2010 Ford F-250/F-350 Super Duty. ICON also recommends specific ICON Alloys wheel sizes (17x8.5", 18x9", and 20x9") and 35x12.50" tires as aftermarket options; tires larger than 35" may require fender trimming.

Are the shocks serviceable after installation?

Yes. Every shock in the ICON K63112 system is fully rebuildable and revalveable. The coilover design also allows for the addition of a secondary front shock if the application calls for it, without requiring new mounting hardware.

What components are included in this system?

The ICON K63112 Stage 2 Coilover Conversion System includes a front box kit, a 2.5 VS rear bolt-in coilover conversion kit, an adjustable track bar with FK rod end bearing, a radius arm drop kit, a 5-inch rear block kit, a rear 17-inch U-bolt kit, and a rear 2.5 VS impact-extruded shock pair. The system ships in multiple boxes at a combined weight of 190 lb.
