Zone Offroad 1999-2004 Ford Super Duty 4wd 6" Suspension System. The newest offering for the leaf-sprung Super Duties is built around massive 9-leaf full height front leaf springs. The leaf springs thin, multi-leaf design provides a great ride while maintaining heavy-duty nature of the Super Duty. By making the springs out of 9 leafs we are able to keep the spring arch low which improves the ride. In addition, when the springs get loaded down, all of the leafs engage in a progressive nature and hold up to the added weight without sagging. To make the steering function as well as the springs, a dropped pitman arm and track bar relocation bracket are included. Bump stop relocation brackets keep the suspension from compressing too far and Nitro shocks keep the ride smooth and controlled. For the 2000-2004 models, the factory sway bar is retained, utilizing the factory mounts ability to be "flipped" at the frame. For 1999 models, new sway bar links are provided - which accounts for the slightly higher kit price. In the rear, full-height 5" blocks replace the factory components and add-a-leafs help get the last little bit of lift needed for a level ride stance.
