ICON Stage 3 Coilover Conversion System for 2023-2026 Ford F-250/F-350 Super Duty 4WD with Radius Arms

The ICON Vehicle Dynamics Stage 3 Coilover Conversion System fits 2023–2026 Ford F-250/F-350 Super Duty 4WD (single rear wheel, non-Cab-and-Chassis models) and delivers 4–5.5" of front lift on diesel trucks without the Tremor package, with lift range varying by engine and Tremor configuration as detailed in the application notes below. The system replaces the front coil bucket with bolt-in 2.5 Series remote reservoir coilovers, adds fabricated radius arms, a track bar drop bracket, a dual opposing steering stabilizer, leaf spring expansion packs for 2" of rear lift, and 2.5 Aluminum Series internal reservoir rear shocks.

Ride Height You Can Adjust on the Vehicle

ICON's 2.5 Series remote reservoir coilovers are ride-height adjustable after installation, so dialing in the exact stance for a load or terrain condition does not require pulling the suspension apart. The remote reservoirs increase shock oil volume and heat-dissipation surface area, resisting the damper fade that builds up on long washboard sections or repeated hard hits. An optional secondary shock can be mounted in the stock coil location using the existing bucket, effectively doubling front damping capacity when conditions demand it.

Fabricated Radius Arms That Raise Ground Clearance

The fabricated steel radius arms are stronger than the OE units and eliminate the drop brackets that stock-geometry lift kits require, which means the chassis sits higher relative to the axle rather than lower. Built-in caster cams allow on-vehicle caster adjustment without removing the arms, and the geometry improves tire clearance at full steering lock. The track bar drop bracket re-centers the axle under the frame and corrects bump steer geometry, reducing steering feedback on rough surfaces.

Steering and Rear Suspension Included

A dual opposing steering stabilizer kit using ICON 2.0 Aluminum Series shocks controls the additional steering feedback that larger tires introduce. At the rear, leaf spring expansion packs add 2" of lift over stock with better small-bump compliance and less axle wrap than lift blocks. ICON 2.5 Aluminum Series internal reservoir rear shocks with a vehicle-specific tune round out the system. The front box kit adds fabricated sway bar drop brackets, aluminum bump stop spacers, and stainless steel extended brake lines.

Features

• Bolt-in front coilovers: 2.5 Series remote reservoir units fit the OE coil bucket location (coil centering cup removal required)
• Ride-height adjustable: front lift set on the vehicle without disassembly
• Fabricated radius arms: built-in caster cams, maintenance-free bushings, improved steering-lock tire clearance, no drop brackets needed
• Dual opposing steering stabilizer: ICON 2.0 Aluminum Series shocks with corrosion-resistant anodized bodies and 5/8" shafts
• Rear lift included: leaf spring expansion packs provide 2" of rear lift; 2.5 Aluminum Series internal reservoir rear shocks with vehicle-specific tune
• Rebuildable and re-tunable shocks: coil springs carry a lifetime guarantee against breakage or sagging

Specifications

Who This Is For and Isn't

This system suits owners of 2023–2026 Ford F-250/F-350 Super Duty 4WD trucks (single rear wheel configurations only) who want a significant front and rear lift with improved on-road ride quality, towing capability, and the ability to run 37" tires without major modification. It works equally well for daily driving, job-site use, and off-road use.

This system does not fit F-350 Cab and Chassis models, dual rear wheel configurations, or 2WD Super Duty trucks. It is not compatible with the stock coil centering cup (removal required during installation). Trucks equipped with Advanced Driver Assistance Systems require ADAS recalibration after installation. Trucks with OnBoard Scales require an additional sensor bracket (part 66204). Trucks with Dynamic Bending Headlamps and/or OnBoard Scales also require part 611081. Installing 2.5 Series or 3.0 Series remote reservoir secondary shocks requires reservoir doubler kit part 611003. Installers must verify adequate clearance between the coilover reservoir and the wiring harness in the upper front-passenger wheel well.

Common Questions

What front lift height will this system give my truck?

The ICON Stage 3 system's front lift range depends on engine and package: 2023–2026 Super Duty diesel trucks without the Tremor package gain 4–5.5"; diesel Tremor-equipped trucks gain 3–4.5"; gas trucks without Tremor gain 4.5–6"; gas Tremor-equipped trucks gain 3.5–5". All figures are over stock ride height on a stock-equipped vehicle.

Does this system fit dual rear wheel or Cab and Chassis Super Duty models?

The ICON Stage 3 Coilover Conversion System fits single rear wheel F-250 and F-350 models only. It does not fit F-350 Cab and Chassis configurations or any dual rear wheel Super Duty variant.

Are secondary shocks included, and can they be added later?

Secondary shocks are not included in this Stage 3 system but can be added after installation. The 2.5 Series coilovers are designed to accept a secondary shock in the stock coil bucket location. If 2.5 Series or 3.0 Series remote reservoir secondary shocks are chosen, the reservoir doubler kit (part 611003) is also required.

What additional steps are required for trucks with driver-assistance technology or OnBoard Scales?

Any Super Duty equipped with Advanced Driver Assistance Systems requires ADAS recalibration after this suspension system is installed. Trucks with OnBoard Scales require sensor bracket part 66204. Trucks with Dynamic Bending Headlamps and/or OnBoard Scales also require part 611081. Installing this system may reduce the accuracy of OnBoard Scales due to a reduction in rear spring rate.

Are the shocks rebuildable, and what does the coil spring guarantee cover?

All shocks in the ICON Stage 3 Coilover Conversion System are fully rebuildable and re-tunable. The coil springs carry a lifetime guarantee against breakage or sagging. Shock bodies use corrosion-resistant finishes: CAD-plated on the front coilovers, hard-anodized on the rear shocks, and anodized on the steering stabilizer shocks.
