Curt mechanically de-scales all of their hitches before applying a thick powder-coat finish, leaving an attractive high-gloss, smooth surface. You will have no worries about your product rusting, as Curt features WeatherTite construction which seals the main body of the hitch. All Curt hitches come with mounting hardware and easy to follow installation instructions. Curt Class-2 Hitches have a 1-1/4 inch receiver opening, and rate up to 2000 pound gross trailer weight (GTW) and 200 pound tongue weight (TW). Curt backs them up with a limited lifetime warranty and a one year finish warranty.
