ICON 4.5" Stage 4 Suspension System 2023 Ford F-250 / F-350

When it comes to lifting your truck, you’ve got plenty of options that go well beyond the amount of lift height and the manufacture. Are you only looking to lift the truck for larger tire fitment, or how about improving the ride quality and overall capabilities of the truck? What about proper alignment with nice level radius arms to avoid bump steer and a dropped track bar to keep it parallel with the drag link like it should be? Have you thought about extended brake lines to ensure you don’t overstretch them with your newfound additional articulation thanks to the progressive rate coil springs and optional leaf spring expansion packs?

All of these are reasons why the ICON Stage 4 Suspension System is a great choice for many that will deliver you the ride height you’re after for larger tire fitment, coupled with improved handling, both on and off the street. 

The Stage 4 Suspension System adds Remote Reservoirs to the front and rear 2.5 VS shocks (or coilovers. The big 2.5" diameter reservoirs significantly increase fluid volume to maximize heat dissipation and prolong damping performance over long sections of rough terrain. Stage 4 also adds ICON's Adjustable Track Bar kit for proper centering of the front axle. This suspension system also includes a Radius Arm Kit upgrade. ICON radius arms are engineered to improve front axle alignment and allow bind-free travel and superior articulation.

4WD 4.5" FRONT AND REAR 2.5 VS RR / PB

ICON’s 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. With a truly vehicle-specific design, these shocks are configured specifically for each application in both length and damping tune. Featuring one-piece impact extruded aluminum cylinders, these 2.5 Aluminum Series shocks offer lighter weight, improved corrosion resistance, and a more uniform finish than traditional plated steel cylinders. Like all ICON shock absorbers, these 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. Remoyte reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. ICON’s unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal “Bump Zone” that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom-out conditions and controls the suspension effectively when compressing at high velocity. If you are looking for a more user-defined tune, consider looking into the Compression Damping Control Valve (CDCV) shocks.
