You cannot just expect to go rocket around off-road at freeway speeds in your 2015-2020 F150 without some serious front suspension upgrades that will allow you to make it out and back in one piece. The first and most important thing to look to first on your build is whether or not it is equipped with heavy-duty coilovers. If not, Stage 3 has a wide selection of large diameter, aggressively valved, and sturdy springed, 2.5 coilovers that are deadly to any overland obstacles trying to hold you back. Tackle some of the toughest terrain and off-road applications that you can find with ease using the superior rebound and compression damping that comes with a high-quality set of aftermarket 2.5 coilovers. Now that you are serious about improving the handling and performance of your F150, keep the train rolling with Rear Shocks and Blocks and Upper Control Arms.
