ICON Stage 2 2.5-Inch Lift Suspension System for 2023 Ford F-250/F-350 4WD Diesel

The ICON Vehicle Dynamics Stage 2 Suspension System delivers a 2.5-inch lift for 2023 Ford F-250 and F-350 Super Duty trucks equipped with 4WD diesel drivetrains, pairing ICON-tuned dual-rate coil springs with 2.5 Aluminum Series piggyback reservoir shocks front and rear. The springs, shocks, and alignment cams are developed and tested together as a matched package, for buyers who want measurably better ride quality and wheel travel without sourcing components separately.

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.

Matched Components, Not Mixed Parts

The Stage 2 kit ships with three assemblies: a front dual-rate diesel coil spring kit with alignment cams (part 62512), a pair of 2.5 VS piggyback front shocks covering 0–2.5 inches of lift (part 67700P), and a pair of 2.5 VS piggyback rear shocks compatible with 0–3 inches of rear lift (part 37705P). The spring rates and shock valving are developed as a unit for this specific truck and engine combination, so the components work together as a calibrated system. Hard-anodized, one-piece impact-extruded aluminum shock bodies with 7/8-inch shafts resist corrosion and are fully rebuildable and revalvable if valving preferences change later.

Diesel-Specific Spring Rates and Front Travel

The dual-rate coil springs are rated for diesel engine weight, not a universal spring adapted for diesel use. ICON states approximately 25% increased front wheel travel over stock, a meaningful gain for trucks that see washboard forest roads, job-site terrain, or loaded towing on uneven pavement. FK Rod End bearings at the shock mounting points reduce deflection and extend service life compared to rubber bushings. The coil springs carry a lifetime guarantee against breakage or sag.

Application Notes That Affect Your Install

Several fitment conditions apply and are worth confirming before ordering. Lift heights are based on a 4WD Crew Cab Diesel configuration; Tremor-package trucks will see approximately 1.5 inches of front lift over stock rather than the full 2.5 inches. ADAS (Advanced Driver Assistance Systems) recalibration is required after installation. An adjustable track bar may be needed to realign the axle laterally. The ICON track bar bracket (part 64039) is recommended for correcting bump steer geometry but is not included in this kit. A braided stainless brake line kit (part 61111) is available separately for installers who prefer not to bend the factory steel lines; it is not required for a complete install. Rare cases may require a 2.6-degree alignment cam on one side for proper caster split. OEM wheel and tire combinations are not compatible with all configurations at this lift height; ICON recommends aftermarket wheels with lower offset.

Features

• Diesel-tuned dual-rate coil springs: rated for diesel engine weight, with lifetime guarantee against breakage or sag
• 2.5 VS Aluminum Series piggyback shocks: vehicle-specific valving front and rear, hard-anodized one-piece aluminum bodies, 7/8-inch shafts
• Fully rebuildable and revalvable shocks: shocks can be serviced and revalved without replacing the entire assembly
• Approximately 25% increased front wheel travel: over stock, per ICON's testing on this application
• FK Rod End bearings: extended longevity and minimal deflection at shock mounting points
• Alignment cams included: front alignment cams ship with the spring kit

Specifications

Who This Is For and Isn't

This system suits owners of a 2023 Ford F-250 or F-350 Super Duty with a 4WD diesel drivetrain who want a 2.5-inch lift with a meaningful improvement in ride quality and front wheel travel for mixed on-road and off-road use, including towing and job-site duty.

This kit does not fit 2024 or later Super Duty models, gasoline-engine trucks, 2WD configurations, or F-350/F-450 Cab and Chassis models. It does not include the ICON track bar bracket (part 64039), the optional braided stainless brake line kit (part 61111), or any aftermarket wheels. OEM wheel and tire combinations may not be compatible at this lift height.

Common Questions

Does this kit fit a 2024 Ford F-250 or F-350?

No. The ICON Stage 2 2.5-inch lift system (K62562) fits only 2023 Ford F-250 and F-350 Super Duty 4WD diesel trucks. ICON's technical notes explicitly state it will not fit 2024 models.

Will this system work on a gas-engine Super Duty?

No. The dual-rate coil springs in this kit are rated for diesel engine weight only. A separate ICON system designed for gasoline-engine Super Duty trucks would be required for a gas-powered F-250 or F-350.

What is and isn't included in the kit?

The Stage 2 kit includes a front dual-rate diesel coil spring kit with alignment cams, a pair of 2.5 VS piggyback front shocks, and a pair of 2.5 VS piggyback rear shocks. The ICON track bar bracket (part 64039) and the braided stainless brake line kit (part 61111) are sold separately and are not in the box.

Do I need to recalibrate my truck's driver-assistance systems after installing this lift?

Yes. ADAS (Advanced Driver Assistance Systems) recalibration is required after installing this Stage 2 suspension system on the 2023 F-250/F-350. This should be performed by a qualified technician with the appropriate calibration equipment.

Will my factory wheels and tires still fit after the lift?

Not necessarily. This system is not compatible with all available OEM wheel and tire combinations. Aftermarket wheels with lower offset and less backspace are recommended; ICON Alloys 17x8.5-inch wheels with 5-inch backspace or 18x9-inch and 20x9-inch wheels with 5.25-inch backspace are specifically noted as compatible options.
