The tubular upper arms use spherical rod ends for precise rear axle location, while the boxed lower arms use polyurethane bushings to add strength and reduce flex under load. The arms are finished in black powder coat for corrosion resistance and are sold as a kit. These trailing arms are made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTubular upper control arms with
