Zone Offroad (kit) 05-11 ford sd radius arm upgrade

These new arms build on the strength and functionality of the previous generation arms and add improved styling and e Offroad branding. Built right here in the USA, these radius arms continue to be built from high strength 1/4" steel, boxed, internally gusseted and fully welded. Designed as a direct replacement for the factory stamped stamped steel arms, these HD radius arms not only add strength, but allow for more caster correction by integrating a lower cam slot and offset washer to dial in caster for 2.5-6" of lift. Large polyurethane bushings are used at the frame mounted end to isolate road noise along with a grease fitting for easy maintenance. The arms feature a new styling cutouts and rivet-on stainless steel e Offroad badging.
