ICON Vehicle Dynamics 2008-2010 Ford F-250/F-350 Super Duty 4WD Diesel 2.5-Inch Lift Stage 5 Suspension System

The ICON Vehicle Dynamics Stage 5 Suspension System delivers a 2.5-inch front lift for 2008–2010 Ford F-250 and F-350 Super Duty 4WD Diesel trucks, pairing dual-rate coil springs with 2.5 Aluminum Series CDCV remote reservoir front shocks and CDCV piggyback reservoir rear shocks for improved ride quality on rough terrain and highway alike. The complete kit is 100% bolt-on with no drilling, cutting, or welding required. Springs are rated for diesel engines only, and the system fits single rear wheel models 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.

External Damping Adjustment Without Lifting a Wrench

Both the front remote reservoir and rear piggyback reservoir shocks are equipped with ICON's CDC Valve, providing 10 positions of compression damping adjustment from soft to hard, all accessible from outside the vehicle without disassembly. For a Super Duty that alternates between loaded towing runs and empty highway miles, that range of on-the-fly tuning means the suspension can be dialed to the load rather than compromised for it.

Reservoir Shocks Built for Sustained Heavy Use

The 2.5 Aluminum Series remote reservoir front shocks and piggyback reservoir rear shocks increase fluid volume, which extends consistent damping performance during prolonged hard use and keeps operating temperatures lower under load. On a diesel-powered Super Duty working construction sites or pulling through rough terrain repeatedly, that thermal headroom translates directly to predictable handling rather than fade-induced harshness late in a run.

A Complete System, Not a Collection of Parts

The Stage 5 kit includes the adjustable front track bar with FK rod end for front axle centering, alignment cams for proper caster correction, and a dual steering stabilizer kit with two ICON 2.0 VS IR stabilizers for wheel control. The rear leaf spring expansion packs, 12-inch U-bolt kit, 1-inch cast block kit, and 2-inch rear bump stop spacer kit address axle wrap and compliance at the rear. ICON guarantees the springs against sagging or breaking for the life of the product, and no drive shaft 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 trucks with a 4WD diesel powertrain and single rear wheels who want a 2.5-inch front lift with externally adjustable damping for mixed use: towing, construction site terrain, dirt roads, and highway driving.

This system does not fit F-350 Cab and Chassis models, dual rear wheel configurations, gasoline-powered Super Duty trucks, or any Super Duty year outside 2008–2010. The springs are rated for diesel engines only and will not suit a gas-engine application. The track bar bump steer bracket (ICON p/n 64039) is recommended to correct bump steer geometry and is not included in this kit.

Common Questions

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

The Stage 5 kit fits 2008–2010 Ford F-250 and F-350 Super Duty 4WD Diesel trucks with single rear wheels. F-350 Cab and Chassis models are not compatible. The rear lift result differs by model: the kit adds 0.5 inches of rear lift over stock on the F-250 but lowers the F-350 rear ride height by 0.5 inches compared to stock.

What does the CDC Valve do and how is it adjusted?

The CDC (Compression Damping Control) Valve on each shock allows 10 positions of compression damping adjustment, ranging from soft to hard. Adjustment is made externally on the vehicle without removing or disassembling the shocks, so the driver can tune the ride to match load or terrain conditions without tools or a lift.

Will this kit work with a gas-engine Super Duty?

No. The dual-rate coil springs in this Stage 5 kit are rated for diesel engines only. A gas-engine 2008–2010 Ford F-250 or F-350 Super Duty is not a compatible application for this system.

Does installation require cutting, welding, or drive shaft modifications?

The Stage 5 Suspension System is a 100% bolt-on kit. No drilling, cutting, welding, or drive shaft modifications are required for installation. Alignment cams are included for caster correction after install.

What wheel and tire sizes are recommended with this lift?

OEM wheels and tires are compatible with this system. ICON recommends aftermarket wheels sized 17x8.5 inches with 5.00-inch backspace and 6mm offset, 18x9 inches with 5.25-inch backspace and 6mm offset, or 20x9 inches with 5.25-inch backspace and 6mm offset. Tires up to 35x12.50 inches are recommended; larger tires may fit but fender trimming or modifications would be required.
