Pushing the limits of standard towing, Curt forged ball mounts are a powerhouse among receiver-style ball mounts. With solid, one-piece construction, each forged ball mount is designed to surpass other 2 in options to accommodate the added stress of heavy-duty towing. They are able to tow up to 15,000 lb of gross trailer weight and up to 1500 lb of tongue weight, giving them more power to handle especially heavy loads. Curt forged ball mounts also come with a thick skin. We coat each ball mount in a black carbide powder coat finish to provide superior rust, scratch and UV protection. A forged ball mount is an excellent choice for hauling all kinds of heavy trailers. Whatever type of load you are towing livestock, industrial equipment, construction materials -- these class 5 ball mounts help you complete the job. Use a forged ball mount to tow large utility trailers, livestock and cattle trailers, toy haulers, RVs and large boat trailers (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Curt forged ball mounts are engineered to be a perfect counterpart to the Curt class 5 Xtra-Duty trailer hitch, making them the ball mount of choice for full-size pickup trucks and SUVs.
