Vastly Improved Ground Clearance, Unmatched Off-Road Performance
The 2017-2019 Super Duty comes with a heaping dose of power, utility and style right from the factory, but it takes a little bit of doing to really unlock the redesigned F250 and F350's full potential. Thankfully, the suspension experts at ICON have done the prep work for you with their 4.5" Stage 4 Suspension System. This highly-advanced suspension setup does it all by jacking up your F250 or F350 to a more aggressive ride height, making room for 37" tires and taking your ride quality and off-road performance to a whole new level. This heavy-duty suspension lift includes two of ICON's extended dual rate coil springs, ICON's complete 4-link kit and a complete set of front and rear Icon 2.5 Piggyback Reservoir shocks with CDC (compression damping control) valves for easy manual adjustment to varying terrains. The 4.5" extended dual rate coil springs achieve improved ground clearance for bigger wheels and tires and more capable off-roading, while the included Icon 2.5 Piggyback Reservoir w/ CDC Valve front and rear shocks perform extremely well on and off the pavement. A comprehensive 4-link system is incorporated to further improve performance by eliminating suspension bind commonly experienced with factory radius arms during articulation. The 4-link system "frees up" your front end to maintain positive caster through the range of travel for unparalleled ride quality in all conditions. An adjustable track bar designed specifically for the 2017-2019 Super Duty is also included to maintain proper steering geometry. All together, this complete suspension system will deliver optimal control over a variety of rugged terrain and will maintain precise, OE handling and ride quality.
Vehicle-Specific Shock Tuning
This Stage 4 Suspension System by Icon has been designed specifically for your 2017-2019 Super Duty to provide the ultimate upgrade in off-road performance and ride quality. The included 2.5 Piggyback Reservoir shocks by Icon are built with a 6061 billet aluminum manifold a few inches below the top cap of the shock which creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. The nitrogen-charged shocks feature a remote reservoir design that improves heat dissipation to reduce shock fade during heavy-duty and prolonged performance. These fully rebuildable and revalvable shocks include externally adjustable valves that restrict oil flow into the reservoirs, delivering 10 levels of compression damping force. Corrosion resistant CAD plated shock bodies with 7/8" shafts and FK rod end bearings ensure optimal strength and dependability with minimal deflection no matter how much abuse they're put through. ICON's Stage 4 Suspension System will have your 2017-2019 Super Duty gliding over the most uncertain terrain and towing/hauling like an absolute beast. This setup achieves 50% increased wheel travel over stock, dramatically improving off-road capability and durability. This is the ideal suspension setup for maximum towing, hauling, and off-road capability, however ICON's premium suspension alignment components ensure that your OE ride quality isn't touched.
