Looking to take your leveling kit to the next level? Our new uniball radius arms improve geometry for better handling both on and off-road, have increased ground clearance and are considerably stronger than the stock versions.

We’ve been building radius arms for 20+ years for Ford vans, trucks and i-beam race trucks. For our new 2005-2022 Ford F-250/350’s radius arms, we went with a thick 3/16” boxed construction design for added ground clearance and thinner cross section for more tire clearance when turning without sacrificing strength. We correct and increase positive caster geometry for better handling and stability; eliminating the dreaded “death wobble” some can experience from time to time. We use FK “Made in the USA” heat-treated, PTFE (teflon) lined 1” uniballs for the frame pivots with our CNC machined stainless mis-alignment spacers and the factory hardware. This allows for smooth and bind free movement and zero flex under braking with little to no maintenance. These bolt right into the factory mounts so you’re not deceasing ground clearance or adding leverage to the frame rails with a drop bracket. If and when the uniballs need to be replaced, they’re easily serviceable and readily available. For the 2008-2022 models, we also supply bracketry and hardware to correct the sway-bar geometry.

The radius arms are CAD designed, laser cut, CNC formed, MIG welded, sandblasted, powder coated in our trademark Camburg gray and are ready to install with all the necessary hardware included.
