Zone Offroad 2017 f250/350 4in - dsl - 3 leaf main

This complete suspension system includes full length replacement coil springs designed specifically to offer improved on-road/off-road performance with the weight of the diesel Super Duty. To maintain the suspension geometry with the additional lift a pair of radius arm drop brackets are bolted into the factory frame mounts to correct the caster positioning. Steering correction comes from a forged drop pitman arm to improve operating angle while a massive 1/4" steel fabricated track bar drop bracket is used to reposition the track bar mount to re-center the front end and keep the steering linkage angles in phase for predictable handling. Also included for the front of this 4" lift kit are sway bar relocation brackets to correct sway bar operating angle, brake line drop brackets to reposition the factory lines, bump stop extensions to control suspension compression and new steering stabilizer mounts to install the Zone nitro single stabilizer cylinder in place of the factory steering stabilizer.
