Easily attaches the trailer frame to the vehicle hitch where solid-steel spring bars use friction to resist sway. A weld-on tab allows left-hand use or use without a weight distribution hitch. Glossed powder-coat finish resists rust and chips. Rated for up to 3,500 lbs. gross trailer weight and 350 lbs. tongue weight. Kit includes sway-control unit, trailer-attachment ball with hardware, hitch-mounted attachment ball, weld-on tab, mount-reinforcement plate and attachment clips.
