ICON Stage 6 2.5-Inch Lift Suspension System for 2008-2010 Ford F-250/F-350 Super Duty 4WD Diesel

The ICON Vehicle Dynamics Stage 6 Suspension System delivers a 2.5-inch front lift for 2008–2010 Ford F-250 and F-350 Super Duty 4WD Diesel trucks (single rear wheel models only), pairing dual-rate coil springs with 2.5 Aluminum Series CDC Valve remote reservoir front shocks and piggyback reservoir rear shocks for tunable, consistent damping on towing runs, construction-site terrain, and dirt roads alike. The system is a complete bolt-on package with no drilling, cutting, or welding required, and it fits OEM wheels and tires without modification.

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.

Tunable Damping for Every Condition

Both the front and rear shocks carry ICON's CDC Valve, giving drivers 10 externally adjustable compression damping settings from soft to hard without removing a wheel or opening the hood. That range matters on a working truck: dial softer for an unladen highway run, firmer for a loaded tow or a rutted job-site road, and return to the previous setting in seconds. The 2.5-inch aluminum remote reservoir (front) and piggyback reservoir (rear) designs extend consistent damping performance during sustained heavy use by keeping fluid cooler than a standard monotube or twin-tube shock can manage under the same load.

Radius Arms That Eliminate Caster Compromises

The fabricated, fully boxed ICON radius arms include on-vehicle caster adjustment, removing the need for caster correction bushings or drop brackets after the lift is installed. A sealed pivot bushing reduces road noise and extends service life. The arm profile is optimized for tire clearance at full steering lock, allowing a 37-inch tall tire to clear without contacting the arm.

Front Axle Control and Rear Compliance

An adjustable front track bar with a heavy-duty FK rod end keeps the front axle centered and minimizes lateral deflection under load, addressing a common weak point on lifted solid-axle trucks. At the rear, leaf spring expansion packs with blocks and U-bolts increase compliance and reduce axle wrap. ICON's dual steering stabilizer kit, using two 2.0 Aluminum Series stabilizers in opposing configuration, smooths wheel control across all conditions. The system's springs carry a lifetime guarantee against sag or breakage, and no driveshaft modifications are required.

Specifications

Who This Is For and Isn't

This system suits owners of 2008–2010 Ford F-250 or F-350 Super Duty 4WD Diesel trucks with single rear wheels who want a 2.5-inch front lift with externally tunable damping for towing, work-site use, and mixed on- and off-road driving, without modifying the driveshaft or replacing OEM wheels.

This system does not fit F-350 Cab and Chassis models, dual rear wheel configurations, gasoline-engine Super Duty trucks, or any Ford Super Duty outside the 2008–2010 model years. The springs are rated for diesel engine weight only. Tires taller than 37 inches may require fender trimming. ICON track bar bracket part #64039 is separately recommended to correct bump steer geometry and is not included in this kit.

Common Questions

Does this system fit a Ford F-350 with dual rear wheels?

No. The ICON Stage 6 system for 2008–2010 Ford F-250/F-350 Super Duty 4WD Diesel fits single rear wheel models only. Dual rear wheel (dually) configurations are not compatible with this kit.

Will this kit work on a gasoline-powered Super Duty?

No. The coil springs in this Stage 6 system are rated for diesel engine weight only and are not appropriate for gasoline-engine Ford F-250 or F-350 Super Duty trucks.

How is the ride firmness adjusted?

The front and rear shocks each include an external CDC Valve with 10 compression damping settings ranging from soft to hard. Adjustments are made on the vehicle without removing wheels or disassembling any suspension components.

What happens to the rear ride height on an F-350?

On an F-250, the rear blocks in this Stage 6 kit replace the OEM rear blocks and add approximately 0.5 inch of rear lift over stock. On an F-350, the same blocks lower the rear ride height by approximately 0.5 inch compared to stock due to differences in OEM block height between the two models.

Is drilling, cutting, or welding required to install this system?

No. The ICON Stage 6 Suspension System is a 100% bolt-on kit. No drilling, cutting, or welding is necessary for installation, and no driveshaft modifications are required.

What is the largest tire this system accommodates without modification?

The ICON radius arms in this Stage 6 system are profiled to clear a 37-inch tall tire at full steering lock without contact. Tires larger than 37 inches may fit but could require fender trimming or other modifications.
