The new Zone Offroad 2011-16 Ford Super Duty 4" radius arm suspension lift features tough replacement radius arms that are considerably stronger, made of inch steel, fully boxed, and utilizing large 2-1/2 inch, greasable urethane bushings. The arms bolt directly into the stock location, and position the axle for the proper caster and wheel location. The lower mount point at the axle utilizes our popular cam lock design, making it adjustable for 4 inch or 6 inch of lift.

Engine specific front coil springs are designed to not only ride great, but will hold up over the long haul. A 1-1/2 inch solid steel track bar is included to properly center the axle after lifting. This track bar features new oversized, high-durometer (hardness) urethane bushings for long term performance and improved handling. The system is comes with custom valved Zone hydraulic or choose to upgrade to the Nitro shocks for better towing and handling performance.

The rear is lifted with a 5 inch block used to replace the factory block instead of stacking blocks. This system is also one of the easiest installations on the market because of the use of a front track bar and rear block kit. If you are looking to not only lift your Super Duty, but improve the looks, strength, and feel of your suspension, choose the Zone Offroad radius arms system.
