2005-2007 F250 & F350 4WD Zone Offroad 4" Radius Arm Lift Kit (Diesel) F21

Zone Offroad 4" Radius Arm Lift Kit

The Zone Offroad 2005-07 F-250 / F-350 4" Radius Arm Suspension Lift features tough replacement radius arms that are considerably stronger - made of fully boxed, 1/4" steel and utilizing large 2-1/2" greaseable 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 hold up over the long haul. A solid steel 1-1/2" 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 comes with custom valved Zone hydraulic shocks or choose to upgrade to the Nitro shocks for better towing and handling performance. The rear is lifted by replacing the factory blocks with 5" blocks instead of stacking blocks. This system is also one of the easiest installations on the market.

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 Lift Kit.

For a limited time, Stage 3 Offroad is offering the Nitro Series Shock Upgrade at NO CHARGE! No strings attached. Just add them using the drop-down menu above.
