Curt 42225 Switch Ball Trailer Ball Set, 1-7/8, 2, 2-5/16 in Dia Ball, 1 in Dia Shank, Steel

curt switch ball trailer balls are a breakthrough in trailer ball technology. As a result of curt innovation and engineering genius, switch balls offer the ultimate in convenience and reliability for a variety of light-duty and medium-duty towing applications. Essentially, a curt switch ball is a trailer ball shank with a removable head. With its exclusive J-groove design, the switch ball trailer ball allows different heads or ball sizes to be places on the shank for accommodating different coupler sizes. This means there is no need to switch between ball-mounts or even to own a second ball-mount to fit an additional trailer. When you need to make the switch, simply twist the switch ball head, lift it off and twist-on another. The J-groove ensures a solid hold on your trailer, while still allowing for easy removal of the trailer ball without tools or pins. This curt switch ball trailer ball set comes with two ball attachments. Ball one features a ball diameter of 1-7/8 in and ball capacity of 3500 lb. Ball two has a 2 in ball diameter and a ball capacity of 6000 lb. Ball three has a 2-5/16 in dia and a ball capacity of 8000 lb. The shank measures 2-1/4 in L and 1 in Dia. We construct these interchangeable hitch balls from premium-grade steel for strength and give them a bright nickel chrome finish for a long life. To ensure your safety and provide you with a tow ball you can depend on, curt switch balls are independently tested in accordance with SAE J684.
