CURT 1-7/8" trailer balls are constructed from high-strength steel to match the towing power of your class 1 or class 2 trailer hitch and ball mount and come with fine threads on the shank for improved holding strength. Having a trailer ball that matches your coupler size is absolutely essential. At CURT, we engineer our trailer balls to be precisely fitted. When we stamp 1-7/8" into the top of each hitch ball, we actually mean 1-7/8".This CURT tow ball features a ball capacity of 3,500 lbs. It is able to tow most utility trailers, boat trailers, campers, smaller livestock trailers and some recreational vehicle haulers (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). As with any trailer, be sure that your towing equipment is capable of handling the load before hitching up. This trailer ball also features a 1" shank diameter, a 3" shank length, 0" of rise and a nickel-chrome finish to protect against corrosion and wear. Like all CURT trailer balls, our 1-7/8" balls are tested for your safety and meet all U.S. VESC specifications.
