SuperATV Polaris RZR RS1 High-Clearance Boxed Radius Arms replace the stock rear radius arms on your Polaris RZR RS1 with high-strength steel construction and a high-clearance shape that keeps the arms up and away from rocks, stumps and ruts. Adjustable heim joints let you set camber and toe to your setup, so the rear end tracks straight after a lift, wider wheels or long-travel changes, and the arms hold up to hard landings, whoops and rocky trails that bend stock links.
The arms bolt to the factory mounting points using the published install instructions.
