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.

For the rear of this 4" lift system, a replacement block is used to lift and level the stance, and eliminate the need to stack blocks. These kits maintain the factory leaf springs and overloads so your truck maintains its tow capability. A 5" fabricated block has an integrated bump stop wing and bolts into place using a pair of extended black e-coated u-bolts. Due to the factory equipped 2-leaf main springs or a 3-leaf main springs w/ overload, Zone offers multiple rear box kits with u-bolts to fit your particular setup.

Your choice of Zone hydro (hydraulic) or nitro (gas) shocks are available to improve your trucks ride quality.

If you're looking to get more out of your 2017 Ford Super Duty then this kit is for you. Take your 2017 Super Duty to new heights with this 4" lift kit from Zone Offroad backed by the peace of mind with Factory Protection Plus.
