Class 1 & 2 trailer hitches come with a ball mount and pin and clip. All that"s left is to pick up a hitch ball and wiring kit and you"ll be towing in no time. All CURT hitches feature WeatherTite™ construction, which prevents rusting from the inside out by sealing the main body of the hitch. The receiver tube has an open back end to allow for easy cleaning and for dirt and moisture to pass through and not get trapped as is common with other brands of hitches. All CURT hitches come with mounting hardware and installation instructions. CURT is the only hitch company in the industry that mechanically de-scales all of our hitches before applying a thick powder coat finish, which is baked on for a high-gloss, smooth surface. CURT trailer hitches are simply the most attractive, most durable and toughest hitch on the market. You won’t find better quality and value anywhere!
