Zone ZONF19-ZN 4″ Lift Kit | 11-16 Ford F-250/F-350 Super Duty 4WD Gas |WITH Overload Springs

The revolutionary new Zone 4\” system features new front coil springs that are designed to not only ride great, but will hold up over the long haul. A 1-1\/2\” solid steel track bar is included to properly center the axle after lifting. This track bar features new oversized, high-durometer urethane bushings for long term performance. The rear kit comes with 5\” blocks to replace your factory blocks so there is not stacking of blocks when you are in the Zone. This reduces rear axle wrap compared to other similar systems on the market. With the front replacement track bar and the rear block kit, this system is one of the easiest installations on the market for a 4\” system.
