Do you just want to "lift" your SuperDuty, or do you want a REAL suspension system to improve the ride and capabilities of your truck, while also lifting it 4.5"? This Stage 4 kit comes with all of the right pieces to include four link conversion and 2.5" adjustable piggyback shocks.
The Stage 4 system is perfect for on-road and off-road use including towing, job site duty and hardcore off-road adventure. ICON's Stage 4 System is comprised of dual rate coil springs, adjustable track bar, 5" block kit, and ICON CDC Valve 2.5 Series front and rear piggyback reservoir shocks.
The Stage 4 system sees the inclusion of the ICON Vehicle Dynamics Ford Super Duty 4-Link kit, which further improves performance by eliminating suspension bind commonly experienced with factory radius arms during articulation. This "freeing up" of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to an unparalleled ride quality in all conditions. With the endless hours ICON has spent testing and tuning their suspension components and shocks as a complete package, you can be rest assured you have the best suspension solution on the market.
