Bring your SuperDuty to new heights with this complete suspension system from Zone! This Zone Offroad 4" radius arm suspension lift features tough replacement radius arms that are considerably stronger, made of 1/4" steel, fully boxed, and utilizing large 2-1/2", 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" or 6" 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" 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 rear is lifted with a 5" 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 arm system.
