Zone Offroad is now offering updated HD radius arms for the late model RAM 2500 and 3500 trucks. These new arms build on the strength and functionality of the previous generation arms and add improved styling and Zone Offroad branding. Built right here in the USA, these radus 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 3-6.5" of lift. Large polyurethane bushings are used at the frame mounted end to isolate road noise along with a grease fitting for easy maitenance. The arms feature a new styling cutouts and rivet-on stainless steel Zone Offroad badging.
