4" F250 / F350 2017-2019 Ford 4WD (w/gas engine) Lift Kit by Zone

This Zone Off-Road F49 / F106 4-inch lift kit for the Ford F250 and F350 trucks (w/gas engine) is a great upgrade that will allow for the use of up to 37-inch diameter tires for an awesome, aggressive look. Using Zone full-length replacement coil springs designed specifically to offer improved on-road/off-road performance with the weight of the diesel Super Duty. A pair of radius arm drop brackets are bolted into the factory frame mounts to correct the caster positioning and maintain the suspension geometry with the additional lift. Steering correction comes from a forged drop pitman arm to improve the operating angle. In contrast, 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 the 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.
