1-7/8" Trailer Ball - 3/4" x 1-5/8" Shank  - 2,000 lb. Capacity - ChromeCURT 1-7/8" trailer balls are constructed from high-strength steel to match the towing power of 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, the trailer balls are engineered 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 2,000 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 the towing equipment is capable of handling the load before hitching up. This trailer ball also features a 3/4" shank diameter, a 1-5/8" shank length, 0" of rise, and a nickel-chrome finish to protect against corrosion and wear.
