Trailer Hitch
However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Kia Optima and Hyundai Sonata (to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.

Vehicle 4 Way Converter
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 Kia Optima (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.
