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 17,000 lbs. and an extra-high tongue weight capacity of 2,550 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 F350 Super Duty, F450 Super Duty and F550 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 2,550 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.
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Ford F250 and F350 Super Duty (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.
