The Zone Offroad 6" lift kit for the Ford F250, F350 Super Duty features massive front leaf springs with 9 leafs. These springs were designed with thin, multi-leafs to provide not only a great ride but to maintain the heavy duty nature of the Super Duty. The low spring arch of the 9 leafs will actually improve the ride. Additionally, when the springs are loaded down, the leafs engage in a progressive nature to hold the added weight without sagging. The factory sway bar is retained. The factory sway bar mounts are flipped at the frame. Features of this Zone lift kit for your Super Duty include:

Front 9-leaf leaf springs with bushings and u-bolts
Track bar relocation brackets
Bump stop relocation brackets
Pitman arm
5" Rear block kit (replaces factory block)
Rear add-a-leafs
