ICON Vehicle Dynamics Stage 9 Coilover Conversion System for 2023-2026 Ford F-250/F-350 Super Duty 4WD

The ICON Vehicle Dynamics Stage 9 Coilover Conversion System is a complete front and rear suspension upgrade for 2023–2026 Ford F-250 and F-350 Super Duty 4WD trucks (single rear wheel models only), delivering 4–5.5" of front lift on diesel models without the Tremor package, with lift range varying by engine and Tremor configuration as detailed in the specifications below. The system ships as one unit: coilovers, secondary shocks, 4-Link kit, steering stabilizer, rear blocks, and electronic damping control, all tuned and tested together.

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.

Active Damping on Every Shock

ICON Intelligent Control (IIC) reads G-forces and chassis movement through onboard sensors and adjusts compression damping at each individual shock in near real time via the Compression Damping Electronic Valve (CDEV). Once configured through the IIC app (iOS required), the system operates without driver input, so the suspension responds to terrain changes whether the truck is loaded for a job site or running a washboard gravel road. The 2.5 Series CDEV remote reservoir front coilovers and the 2.5 Aluminum Series CDEV piggyback rear shocks both carry vehicle-specific valving, meaning the tune reflects the actual weight and geometry of the Super Duty rather than a generic calibration.

Doubled Front Damping Capacity

The Stage 9 system mounts 2.5 Aluminum Series CDCV remote reservoir secondary front shocks in the stock shock location alongside the primary coilovers, effectively doubling front damping ability. Remote reservoirs on both the primary and secondary front shocks increase oil volume and heat-dissipation surface area, resisting the damper fade that builds during sustained hard use. The 2.5 Aluminum Series CDEV piggyback reservoir rear shocks carry a vehicle-specific tune and represent a step up in performance from 2.0 Aluminum Series units.

Geometry Correction from Front to Rear

The ICON 4-Link kit replaces the factory radius arms with a configuration that eliminates suspension bind during articulation and maintains positive caster through the full range of wheel travel. A fabricated track bar drop bracket re-centers the axle under the frame and corrects bump steer geometry; the included adjustable track bar allows on-vehicle fine-tuning of track alignment and eliminates the deflection of OE track bar bushings. The 2.5 Centerline steering stabilizer kit (a single 2.5 Aluminum Series shock with a piggyback reservoir) provides stronger steering damping than dual 2.0 stabilizer setups and improves ground clearance. Heavy-duty fabricated 5" rear blocks and a U-bolt kit complete the rear lift.

• 2.5 Aluminum Series CDCV Secondary Front Shocks: mount in stock location to double front damping capacity
• ICON 4-Link Kit: eliminates radius arm bind, maintains positive caster through full travel, allows on-vehicle caster adjustment
• IIC Electronic Damping Control: near-instantaneous compression damping adjustments via onboard sensors; wireless control through iOS IIC app
• Centerline 2.5 Steering Stabilizer: piggyback reservoir, improved damping and ground clearance over dual 2.0 setups
• Box Kit Included: fabricated front sway bar drop brackets, aluminum bump stop spacers, stainless steel extended brake lines, track bar drop bracket, adjustable track bar

Specifications

Who This Is For and Isn't

This system suits owners of 2023–2026 Ford F-250 or F-350 Super Duty 4WD trucks with single rear wheels who want a complete, electronically controlled suspension lift covering front coilovers, secondary shocks, geometry correction, steering stabilization, and rear lift in one purchase. Primary uses include towing, job site work, washboard gravel, and more aggressive off-road driving.

This system does not fit 2WD Super Duty models, F-350 or F-450 Cab and Chassis configurations, or dual rear wheel models. It does not fit trucks outside the 2023–2026 model years. ADAS recalibration is required after installation, and the IIC electronic control system requires an iOS device; Android is not supported. Removal of the coil centering cup in the factory coil bucket is required for installation. Lift heights stated are for a stock-equipped vehicle; the Tremor package reduces front lift range as noted in the specifications.

Common Questions

Will this system fit my F-350 dually or Cab and Chassis?

The ICON Stage 9 Coilover Conversion System fits single rear wheel F-250 and F-350 Super Duty 4WD models only. F-350 and F-450 Cab and Chassis configurations are explicitly excluded, as are dual rear wheel models.

How much lift will I actually get with the Tremor package?

Front lift range on this Stage 9 system depends on engine and Tremor configuration. Diesel trucks without Tremor gain 4–5.5"; diesel trucks with Tremor gain 3–4.5". Gas trucks without Tremor gain 4.5–6"; gas trucks with Tremor gain 3.5–5". All figures are over a stock-equipped vehicle. Rear lift is 5" via the fabricated rear blocks regardless of configuration.

What does ICON Intelligent Control do, and do I need a specific phone?

ICON Intelligent Control (IIC) uses onboard sensors to monitor G-forces and chassis movement, then makes near-instantaneous compression damping adjustments at each individual shock through the CDEV valve. The system is configured through the IIC app and then operates without driver input. An iOS device is required; the IIC app is not available for Android.

What is included in the Stage 9 system?

The Stage 9 system includes 2.5 Series CDEV remote reservoir front coilovers, 2.5 Aluminum Series CDCV remote reservoir secondary front shocks, the ICON 4-Link kit (frame bracket kit, upper and lower front links), a track bar drop bracket kit, an adjustable track bar, a 2.5 Centerline steering stabilizer kit with piggyback reservoir, 2.5 Aluminum Series CDEV piggyback rear shocks, 5" fabricated rear blocks, a U-bolt kit, the IIC install kit and controller plug kit, a reservoir doubler mount, and a box kit containing fabricated sway bar drop brackets, aluminum bump stop spacers, and stainless steel extended brake lines.

Is ADAS recalibration required after installation?

Yes. Installation of this Stage 9 Coilover Conversion System requires recalibration of Advanced Driver Assistance Systems (ADAS) on the vehicle. This is a mandatory post-installation step and is not performed by the system itself.
