Polyurethane bushings tighten rear axle location and reduce flex under acceleration and braking compared to worn factory rubber, which improves traction and handling. The arms are finished in black powder coat for corrosion resistance and are sold as a pair. These control arms are made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBoxed rear lower control
