2008-10 4WD Ford F250, F350 Super Duty 4" radius arm lift kit, Nitro shocks

Designed to be easier to install than other 4” lift kits on the market, this Zone Offroad lift kit features replacement radius arms that are considerably stronger than factory. They are constructed using ¼” steel and are fully boxed using large 2.5” greasable urethane bushings. By bolting directly to the stock location, they position the axle for proper caster and wheel location. By utilizing the Zone cam lock design, the lower mount point at the axle allows adjustment from 4” to 6” of lift. The solid steel track bar has oversized, high durometer urethane bushings for improved handling and long term performance. To improve the looks of your F250 or F350 Super Duty, add strength and feel or your suspension, the Zone Offroad radius arm system is the one you want. This is a "top shelf" lift kit without the top shelf price.
