ICON is known for creating some of the best coilover leveling kits you can find on the aftermarket because with their kits you're not just balancing out your 2004-2008 5.4L F150 for the looks but also gaining some high-quality suspension components that give you the edge when you're trying to maneuver your truck off the beaten path. While there are multiple stages to choose from with these ICON coilover kits, each includes a strong foundation of high-performance shocks that will dampen the bumps of wash board roads while lessening the "bottoming out" and hard hits you would typically experience with rocky ravines at high speeds with factory stock shocks and springs. These shocks can handle up to 3" of lift from a suitable rear block or Add-A-Leaf Kit to make it sit evenly or even slightly above the coilovers also included in these packages. Their nitrogen-charged monotube shocks feature one-piece linear/digressive pistons and 5/8" nitro-steel shafts that provide excellent ride quality, performance, and reliability under even the most extreme conditions.
Whether you're just getting started but need a much more powerful suspension solution than a standard leveling kit so you can throw on a set of 33" off-road tires and tear it up off-road, ICON provides everything from a Stage 1 Lift Kit that includes coilovers for the front and 2.0 Aluminum Series Shocks for the rear all the way up to their 0-3" Stage 3 Lift Kit that includes extreme performance gear, including fully adjustable front coilovers and large-diameter 2.5" piggy-back style performance shocks. Each of these kits will turn your 5.4L into a stud off-road without sacrificing your ride quality during regular highway and street travel.
We were lucky enough to get invited to tour the ICON Vehicle Dynamics facilities to see how they actually make these awesome shocks and coilovers. At their facility in California where they design, construct and test each component, they push each of their shock systems to the limit to make sure they are powerful enough to stand up to the rigors of high-performance off-road use. They max out each of these shock and coilover systems to the limits in the factory as well as real-world situations to ensure they will be able to stand up to the most intense situations you might encounter off-road which is why they are at the top of our list for leveling/coilover kits.
