Upgrade your lifted RAM HD with HD Boxed Radius Arms for added strength and functionality. Built right here in the USA, these radius arms are 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 maintenance. The arms are finished in a durable textured black powder coat and feature new laser cut stainless steel. Zone Offroad badging that can be painted to customize before riveting on. Arms are sold individually.
