ICON Vehicle Dynamics 2005-2007 Ford F-250/F-350 4.5" Lift Stage 4 Suspension System

The ICON Vehicle Dynamics Stage 4 Suspension System raises 2005–2007 Ford F-250 and F-350 Super Duty trucks (diesel, automatic transmission only) 4.5 inches and pairs ICON 2.5 VS PB CDCV front and rear shocks with a dual-rate front coil spring kit, a 4-Link frame bracket kit, an adjustable track bar, radius arm drop brackets, a rear block kit, and a rear U-bolt kit. Everything needed to complete the front and rear lift ships in one order.

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.

More Wheel Travel, Less Body Roll

The ICON 2.5 VS PB CDCV shocks deliver a 50 percent increase in wheel travel compared to stock, and the system provides 4.5 inches of additional travel from ride height to the front bump stops. Reduced body roll means the truck stays flatter through corners and over uneven terrain, giving the driver more confidence when loaded or towing. Rated towing capacity is unchanged.

Dual-Rate Springs Built for Super Duty Weight

The front dual-rate coil springs are rated for diesel engine weight and carry a lifetime guarantee against sag. A stiffer initial rate handles everyday driving and light loads; the spring transitions to a softer rate as suspension compresses, absorbing larger hits without harshness. The springs are fully compatible with OEM wheels and tires, and the system clears 35-inch tall tires outright; 37-inch tall tires fit with minor fender trimming.

Bolt-On Installation, No Fabrication Required

The Stage 4 system is 100 percent bolt-on, with no drilling, cutting, or welding required. The adjustable track bar with FK rod end restores correct front-end geometry after the lift, and the 2.5-series aluminum shock bodies are anodized for corrosion resistance. No driveshaft modifications are needed. Shocks are fully serviceable. The system ships in multiple boxes.

Specifications

Who This Is For and Isn't

This system suits 2005–2007 Ford F-250 and F-350 Super Duty owners running a diesel engine with an automatic transmission who want a complete, bolt-on 4.5-inch lift with meaningful gains in wheel travel, improved body control, and clearance for up to 35-inch tires without fender modification.

This system does not fit Super Duty trucks equipped with a manual transmission, and the front coil springs are not rated for gasoline engines. Owners of '05–'10 Super Duty trucks should note that the pinch weld on the factory radius arms may contact the radius arm drop bracket hardware. Tires larger than 35 inches require fender trimming.

Common Questions

Does this system work with a gas engine F-250 or F-350?

The front dual-rate coil springs in the ICON Stage 4 system are rated for diesel engines only. The system is not compatible with gasoline-engine Super Duty trucks; a different spring kit would be required for that application.

Is this system compatible with a manual transmission?

No. The ICON Stage 4 Suspension System for 2005–2007 Ford F-250/F-350 is not applicable on vehicles equipped with a manual transmission. It is designed for automatic-transmission Super Duty trucks only.

What tools or fabrication are needed to install this system?

The ICON Stage 4 system is a 100 percent bolt-on kit, with no drilling, cutting, or welding required, and no driveshaft modifications needed. ICON provides an installation guide; professional installation is recommended given the scope of a complete front and rear suspension replacement.

What tires will fit after installing this lift?

The ICON Stage 4 system clears 35-inch tall tires with OEM fenders. Fitting 37-inch tall tires is possible with minor fender trimming. Tires larger than 37 inches will require additional fender modification beyond what the system is designed to accommodate.

Does this system include everything needed for the front and rear lift?

Yes. The Stage 4 system ships with front and rear 2.5 VS PB CDCV shock pairs, dual-rate front coil springs, radius arm drop brackets, an adjustable track bar with FK rod end, a 4-Link frame bracket kit with upper and lower links, a 5-inch rear block kit, and a rear U-bolt kit. No separate shock or spring purchase is needed for this application.
