Choose the Zone Offroad 6 inch Suspension System to lift your truck and clear up to a 37 inch tire. Competitors will tell you how they maintain the factory ride, but Zone Offroad has stepped up the game by including new coil-over struts custom valved for larger tires, improved ride, and optimal handling. A 3-point differential mounting system drops and rotates the front differential to bring the CV shafts and driveshaft back to factory operating angles. Visually compare the Zone Offroad porterhouse knuckles to the chuck roast of the competition. Salivate over the fully cast, CNC machined, and resonant frequency tested knuckles that correct the tie rod and ball joint geometry with no track width change. Heavy main crossmembers are included with your meal and are locked solid with a differential skid plate. Choose your side of rear shock, and we'll fill in the rest with a 5 inch dual pin block kit that offsets the axle closer to the center of the wheel well compared to a standard setup. This kit is all inclusive, so don't look anywhere else, install a Zone Offroad system on your F150 and have no regrets. This system is engineered and manufactured in the USA.
