ICON Stage 1 Suspension System for 2008-2010 Ford F-250/F-350 4.5" Lift

The ICON Stage 1 Suspension System raises 2008–2010 Ford F-250 and F-350 4WD trucks 4.5 inches using a fully bolt-on component set. No drilling, cutting, or welding is required. The kit pairs dual-rate front coil springs with ICON 2.0 Aluminum Series shocks front and rear, and includes radius arm drop brackets, an adjustable track bar with FK rod end, rear lift blocks, and U-bolts. Springs are rated for diesel engines only.

More Wheel Travel Without Sacrificing Tow Capacity

The Stage 1 system delivers a 50% increase in wheel travel over stock, adding 4.5 inches of travel between ride height and the front bump stops. That additional suspension stroke lets the front axle follow terrain more closely under load, reducing the jarring that wears on both the truck and the driver over long off-road runs. Towing capacity is unaffected, and no driveshaft modifications are needed.

Dual-Rate Springs and Tuned Shocks Working Together

ICON's dual-rate front coil springs use two spring rates in a single coil: a softer initial rate absorbs small trail chatter and road irregularities, while the stiffer secondary rate engages under heavier compression to control body roll and support load. The ICON 2.0 Aluminum Series shocks are fully serviceable units, and the front end stays composed over rough ground where a single-rate spring and stock shock would deflect and bounce. ICON guarantees the coil springs will not sag.

Bolt-On Installation, Precise Front-End Alignment

Every component in the Stage 1 kit attaches to existing mounting points. The adjustable track bar with FK rod end corrects front axle lateral position after the lift, restoring factory-spec track alignment without custom fabrication. The radius arm drop brackets relocate the front radius arm pivot to maintain proper arm angle at the new ride height. The system ships in multiple boxes and clears 35-inch tires on OEM wheels; 37-inch tires fit with minor fender trimming.

Specifications

Who This Is For and Isn't

This system suits 2008–2010 Ford F-250 and F-350 4WD owners running diesel engines who want a 4.5-inch lift with improved off-road wheel travel, reduced body roll, and the ability to run 35-inch tires without modifying the driveshaft or sacrificing tow capacity.

The Stage 1 system is not compatible with manual-transmission Super Duty trucks. The coil springs are not rated for gas-engine applications; gas-engine models may also require exhaust modification to clear the front driveshaft. Trucks from the 2005–2010 model years should be checked for pinch weld contact between the radius arm and the drop bracket hardware before finalizing installation. This kit does not fit 2WD configurations.

Common Questions

Does this system work with a gas-engine F-250 or F-350?

The ICON Stage 1 coil springs included in this kit are rated for diesel engines only. Gas-engine 2008–2010 Super Duty trucks are not a supported application for the springs, and gas-engine models may additionally require exhaust modification to clear the front driveshaft at the new lift height.

Will the Stage 1 system work with a manual transmission?

No. The ICON Stage 1 Suspension System for 2008–2010 Ford F-250/F-350 is not applicable on vehicles equipped with a manual transmission. It is designed for automatic-transmission 4WD trucks only.

Do OEM wheels and tires still fit after installing this kit?

Yes. The Stage 1 system is confirmed compatible with OEM wheels and tires. It clears 35-inch tires without modification. Fitting 37-inch tires requires minor fender trimming. ICON also lists recommended aftermarket wheel sizes: 17x8.5-inch with 5.00-inch backspace, 18x9-inch with 5.25-inch backspace, and 20x9-inch with 5.25-inch backspace.

Is any cutting, welding, or drilling required to install this system?

The ICON Stage 1 system is a 100% bolt-on kit. No drilling, cutting, or welding is required, and no driveshaft modifications are needed. Owners of 2005–2010 Super Duty trucks should verify that the radius arm pinch weld does not contact the drop bracket hardware during installation.

Are the shocks rebuildable or serviceable?

Yes. The ICON 2.0 Aluminum Series shocks in this Stage 1 kit are fully serviceable, front and rear, and can be rebuilt or revalved rather than replaced outright when they eventually wear.
