Curt trailer balls are designed for strength, ease of use and, ultimately, to get you to your destination without hassle. Curt 2-5/16" trailer hitch balls are constructed from quality steel and are made with precision to fit your 2-5/16" trailer coupler. They are able to tow a variety of trailers such as utility trailers, boat trailers, campers, and more. These tow balls are an excellent extension of your class 5 trailer hitch and ball mount, and are the ideal choice for most pickup trucks, vans, and SUVs (Note: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). This particular 2-5/16" trailer ball offers a ball capacity of 15,000 lbs. It features a 1-1/4" shank diameter, a 2-5/8" shank length, and a nickel-chrome finish to protect against rust and scratches. With its fine-threaded shank, this 2-5/16" trailer ball also offers an added measure of holding strength and provides smooth installation and torquing. To give you peace of mind while towing to that next destination, we also carefully test our trailer balls and ensure that each one meets U.S. VESC specifications.
