ICON Stage 6 Suspension System with Radius Arm for 2017-2022 Ford F-250/F-350

The ICON Vehicle Dynamics Stage 6 Suspension System with Radius Arm is a complete front-and-rear lift system for 2017–2022 Ford F-250 and F-350 4WD trucks, delivering 4–5.5" of front lift on 2017–2019 models, 4.75–6.25" on 2020–2022 models without the Tremor package, and 3.75–5.25" on 2020–2022 Tremor-equipped trucks. Springs in this system are rated for diesel engines only.

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-Adjustable Coilover Conversion

The bolt-in coilover conversion fits in the OEM coil bucket location, so no cutting or custom fabrication is required to gain end-user ride height adjustability across the full lift range. The 2.5-inch aluminum series shocks feature corrosion-resistant anodized aluminum bodies with 7/8" shafts and are fully rebuildable and revalveable, meaning the system can be serviced and retuned over the life of the truck rather than replaced outright. Vehicle-specific shock valving is calibrated for this platform, improving both on-road composure and off-road control compared to stock.

Radius Arm System for Strength and Tire Clearance

The included ICON Ford Super Duty Radius Arm System uses a fabricated, fully boxed design with a sealed pivot bushing that minimizes road feedback and supports quiet, long-term operation. The arm profile is optimized for tire clearance at full steering lock, allowing a 37-inch tall tire to clear without contacting the radius arm. The radius arms also provide on-vehicle caster adjustment, which is useful when dialing in steering geometry after the lift is set.

Eibach Springs and Dual Stabilizer Package

Eibach coil springs are guaranteed for life against sagging or breakage. The system includes a dual stabilizer kit with two 2.0 VS IR dual-opposing stabilizers, reducing body roll and improving directional stability on and off pavement. FK Rod End bearings are used throughout for extended longevity and minimal deflection under load.

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 front lift in the 4–6.25" range (depending on model year and Tremor configuration), improved wheel travel, and a complete front-and-rear solution in one kit, including radius arms, stabilizers, and rear blocks.

This system is not compatible with gasoline-engine Super Duty trucks, as the springs are rated for diesel engines only. It does not fit 2WD models. A carrier bearing drop bracket (part 33700) may be required and is sold separately. The track bar bracket (part 64039) and brake line kit (part 61110) are also sold separately. Tires larger than 37" may require fender trimming and additional modifications.

Common Questions

Does this system fit both F-250 and F-350 trucks?

The ICON Stage 6 system is designed for 2017–2022 Ford F-250 and F-350 4WD trucks. It does not fit 2WD configurations. Lift height range varies by model year and Tremor package configuration; confirm your specific build before ordering.

What lift height will I get with this system?

Front lift range depends on model year: 2017–2019 trucks achieve 4–5.5" over stock; 2020–2022 trucks without the Tremor package achieve 4.75–6.25"; 2020–2022 trucks with the Tremor package achieve 3.75–5.25". Heights indicated are for a stock-equipped vehicle.

Are the springs compatible with gasoline-engine Super Duty trucks?

No. The coil springs in this Stage 6 system are rated for diesel engines only and are not suitable for gasoline-powered F-250 or F-350 trucks.

What additional parts might be needed beyond what is included?

A carrier bearing drop bracket (ICON part 33700) may be required and is sold separately. The track bar bracket (part 64039) is optional but recommended to correct steering geometry. A braided stainless brake line kit (part 61110) is optional for those who prefer not to bend the factory steel lines. None of these are included in the Stage 6 kit.

Are the shocks rebuildable?

Yes. All shocks in this Stage 6 system are fully rebuildable and revalveable, allowing the damping to be serviced or retuned over the life of the truck without replacing the entire shock body.

What is the largest tire this system will clear?

The radius arm profile in this Stage 6 system is optimized to clear a 37-inch tall tire at full steering lock without contact. Tires larger than 37" may fit but will require fender trimming and additional modifications.
