ICON Stage 3 Suspension System for 2017-2022 Ford F-250/F-350 4-5.5 Inch Lift

The ICON Vehicle Dynamics Stage 3 Suspension System is a complete front-and-rear lift kit engineered for 2017–2022 Ford F-250 and F-350 4WD trucks, delivering a height-adjustable 4–5.5 inch lift on 2017–2019 models, 4.75–6.25 inches on 2020–2022 non-Tremor models, and 3.75–5.25 inches on 2020–2022 Tremor-equipped models. The system ships in multiple boxes and includes every major front and rear component listed below.

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 2.5 VS coilover conversion mounts directly into the factory coil bucket location, so no custom fabrication is needed to gain end-user ride height adjustability across the full lift range. Being able to dial in exact ride height after installation means the truck can be set for daily highway driving or adjusted for heavier loads without pulling the suspension apart again.

Front and Rear System Coverage

Rather than addressing only the front axle, the Stage 3 system pairs the front coilover conversion with a rear 2.5 VS piggyback shock pair, a 5-inch block kit, and a 17-inch U-bolt kit. Matching front and rear valving means the truck's ride dynamics stay balanced on-road and off, rather than the front and rear working against each other after a partial upgrade.

Built-In Geometry Correction

The kit includes an adjustable trackbar, a radius arm drop kit, and a dual stabilizer kit with two 2.0 VS inline-rebound stabilizers in a dual-opposing configuration. Correcting caster, trackbar angle, and steering geometry at the time of the lift reduces bump steer and steering wander that commonly appear when a Super Duty is lifted without these corrections.

Features

• 2.5 Aluminum Series coilover conversion: one-piece impact-extruded aluminum cylinders with CAD-plated bodies and 7/8-inch shafts for corrosion resistance
• Eibach coil springs: guaranteed for life against sagging or breakage; rated for diesel engines only
• FK rod end bearings: extended longevity and minimal deflection
• Fully rebuildable and revalveable shocks: field-serviceable without replacing the entire unit
• Secondary shock provision: coilover conversion allows addition of a secondary shock
• OEM wheels and tires compatible: fits stock wheel and tire configuration

Specifications

Who This Is For and Isn't

This system suits 2017–2022 Ford F-250 and F-350 4WD owners running diesel engines who want a height-adjustable 4-inch-plus lift with matched front and rear performance shocks, geometry correction, and the ability to service or revalve shocks over the life of the truck.

The Eibach springs in this system are rated for diesel engines only and are not appropriate for gas-engine Super Duty trucks. The system does not include the carrier bearing drop bracket (part 33700), which may be required depending on the application; the track bar bracket (part 64039) and brake line kit (part 61110) are also sold separately. Installation requires removal of the coil centering cup from the factory coil bucket. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm (California Proposition 65).

Common Questions

Does this Stage 3 system fit both 2017–2019 and 2020–2022 Super Duty trucks?

The ICON Stage 3 system fits 2017–2022 Ford F-250 and F-350 4WD trucks, but the front lift range differs by year. On 2017–2019 models the front lifts 4–5.5 inches over stock; on 2020–2022 non-Tremor models it lifts 4.75–6.25 inches; on 2020–2022 Tremor-equipped trucks it lifts 3.75–5.25 inches.

Are the springs in this kit compatible with a gas-engine F-250 or F-350?

No. The Eibach coil springs included in this Stage 3 system are rated for diesel engines only. Owners of gas-engine 2017–2022 F-250 or F-350 trucks should not use this kit without confirming spring compatibility with ICON Vehicle Dynamics directly.

What components are not included that may be needed for a complete installation?

The Stage 3 system does not include the carrier bearing drop bracket (ICON part 33700), which may be required depending on the specific truck. The track bar bracket (part 64039) is optional but recommended for steering geometry correction. A brake line kit (part 61110) is also available separately for owners who prefer not to bend the factory steel lines.

Can the shocks in this system be serviced or retuned after installation?

Yes. All shocks in the ICON Stage 3 system are fully rebuildable and revalveable, meaning they can be serviced and retuned without replacing the entire unit. The coilover conversion also allows for the addition of a secondary shock; contact ICON Vehicle Dynamics for secondary shock options.

Will OEM wheels and tires fit after installing this system?

Yes, the ICON Stage 3 system is confirmed compatible with OEM wheels and tires. For aftermarket fitment, ICON recommends 17x8.5-inch wheels with 5.00-inch backspace and 6mm offset, 18x9-inch with 5.25-inch backspace and 6mm offset, or 20x9-inch with 5.25-inch backspace and 6mm offset, paired with up to 37x12.50-inch tires without modification.
