Delivering top-tier ride quality starts with top tier parts and our Fabricated Radius Arms for your 2005-2021 Ford Super Duty should be the starting point for your custom suspension. Conceived through CAD-assisted engineering, the heart of the Ford Radius Arms is an internal network of X-Braces and gussets that lock all facets into one cohesive monolith. Incorporated into the arms are a formed channel that relieves tire rub on the Radius Arm, making room for even the most advanced and aggressive off-road tires and deep-offset aftermarket wheels. Also featured are fully serviceable 3" Spherical Bearings that eliminate the kinetic energy issues associated with vulcanized bushings. Your factory ABS harness is kept out of harm's way thanks to an included clamp, while your shocks are saved from top-out damage by our Quad-Wrap Limit Straps. Easily bolted on, the Fabricated Radius Arms replace your factory arm while using factory mounts and brackets. 4.5"+ Lifts will require the Carli Radius Arm Drops, sold separately.
