This 4.5" System for the 2011-2016 Super Duty is one of the best riding suspension systems ICON has ever developed. This system has been engineered using the highest quality materials and components. The dual rate front coil springs combined with our ICON 2.0 Aluminum Series shocks give these trucks the performance they so desperately need. This system comes complete with front coils, shocks, radius arm drop down brackets, rear blocks, U-bolts, and our patented adjustable track bar giving the front end of these trucks perfect track alignment.
