ICON Vehicle Dynamics is an industry leader when it comes to Ford Super Duty performance. Our engineers have spent countless hours under these trucks and behind the wheel developing some of the most refined suspension systems available. Increasing wheel travel and ride comfort is standard operating procedure at ICON, but our engineers aimed high to produce a suspension solution that also maintained the Super Duty's towing capacity. ICON's 7" Suspension System for the 2011-2016 Super Duty yields enough lift to clear 37" tires while providing excellent ride characteristics across a wide variety of terrain on and off-road. Each component of this suspension system has been specifically engineered to work in union with other ICON parts to extract maximum performance out of the vehicle. Our Stage 4 System is comprised of 7" lift dual rate coil springs, fabricated radius arm drop mounts with brushed stainless badges, track bar drop bracket, bump stop extensions, sway bar links, a forged pitman arm, brake line brackets, rear 5" lift progressive rate leaf springs w/ U-bolts, and 2.5 Series piggyback reservoir front & rear shocks. ICON 2.5" reservoir shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use.
