When we came to the limits of towing capacity, we wanted to know what else was out there. What could we discover off the beaten path? So, we kept going. CURT class 5 Xtra Duty hitches begin a class of their own, beyond class 4 and beyond anything the standards dictate. They are designed for the hard road where only full-size pickup trucks, vans and SUVs dare to tread. They are capable of pulling almost any heavy-duty trailer, including toy haulers, dump trailers, logging trailers, small yacht trailers and more (NOTE: Never exceed the lowest weight capacity of any towing component). This particular Xtra Duty class 5 trailer hitch offers a gross trailer weight capacity of 16,000 lbs. and an extra-high tongue weight capacity of 2,400 lbs. It features a 2" x 2" receiver tube opening to accept a ball mount or hitch-mounted accessory, such as a cargo carrier or winch mount. It is designed to be a custom-fit trailer hitch for certain years of the Ford F250 Super Duty and F350 Super Duty (to verify compatibility with your vehicle, see application info). For a little extra towing power and stability, this class 5 hitch can also be used in combination with a weight distributing hitch. It is rated for 17,000 lbs. WD and 2,400 lbs. WDTW. In our drive to create a more powerful hitch, CURT has not neglected the finer details. Our class 5 trailer hitches are welded with precision and go through multiple stages of cleaning to create a smooth surface that is ready to accept our co-cured finish. To protect them from corrosion, chipping and UV damage, these hitches are immersed in a liquid A-coat and then finished in a high-quality black carbide powder coat. They come with grade-8 mounting hardware for solid installation.
CURT custom wiring is the easiest way to outfit your vehicle with a trailer wiring connection. Each harness is engineered for a specific make and model and uses an OEM-compatible plug, so no cutting or splicing is required during installation. Provides a 4-way flat connector socket for tail lights, brake lights and turn signals. Includes a dust cover and is backed by a limited one-year warranty.
