Zone Offroad F144N Radius Arm Suspension Lift Kit with Nitro Shocks - 5-Inch

The Zone Offroad F144N is a complete 5-inch radius arm suspension lift kit engineered specifically for 2023+ Ford F-250 and F-350 Super Duty 4WD diesel trucks. This kit delivers everything needed to properly elevate your Super Duty and unlock clearance for up to 37-inch tires, with Zone Nitro front and rear shocks included for an upgraded damping experience straight out of the box.

Up front, the kit utilizes diesel-specific full-length coil springs for a smooth, controlled ride. Heavy-duty fabricated steel radius arms correct caster alignment while maximizing ground clearance, and a forged drop pitman arm along with a heavy-duty track bar relocation bracket restore proper steering geometry and re-center the front axle after the lift. A 3-inch rear block kit with radiused U-bolts levels the rear stance to match the front lift height.

The included Zone Nitro Series shocks feature a pressurized nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving for responsive damping on- and off-road. The 2-inch shock bodies use a large 1-3/8-inch fluon-banded piston, self-lubricating seals, and a 14mm hardened chrome shaft for long-term durability.
