Upgrade your leveling kit with our new uniball radius arms for 2005-2022 Ford F-250/350 trucks. These arms improve handling on and off-road, increase ground clearance, and are stronger than stock versions. They feature a 3/16" boxed construction design for added ground clearance and thinner cross section for more tire clearance when turning. The arms correct and increase positive caster geometry for better handling and stability, eliminating "death wobble." We use FK heat-treated, PTFE lined 1" uniballs for smooth movement and zero flex under braking. The arms bolt right into the factory mounts and are easily serviceable. For 2008-2022 models, we provide bracketry and hardware to correct sway-bar geometry. The arms are CAD designed, laser cut, CNC formed, MIG welded, powder coated, and come with all necessary hardware. They are compatible with 2-3.5" of lift and have a maximum wheel backspacing of 5.25" with 37" tires (4.75" backspacing recommended).
