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 BMW 328xi and 335xi (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
CURT custom wiring is the best option for equipping your vehicle with a trailer wiring connector. It offers a vehicle-specific solution with no need for cutting, splicing or soldering. However, if custom wiring is not available for your specific vehicle, CURT offers the taillight converter -- a universal trailer wiring option. This CURT taillight converter provides a standard 4-way flat connection for hooking up your trailer lights to your vehicle. It features highly durable construction, able to withstand harsh elements, road salt and vibrations. The converter is built with a potted enclosure in which the electrical components are encased in a solid compound that seals them off from moisture and impacts. Even when mounted outside, underneath the vehicle, it provides long-lasting dependability. This taillight converter is compatible with a wide variety of vehicles, including models from Dodge, Ford, GM, Honda, Kia, Mazda, Nissan, Subaru, Toyota, Volkswagen, Volvo and many others (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). The converter is designed to convert a 3-wire vehicle system to function with a 2-wire trailer system. The converter features color-coded wires and a wiring guide for easier installation, and it comes with snap locks for a secure connection (a powered taillight converter wiring kit, such as the CURT #55151, is also required for installation). Most CURT taillight converters are constructed with surface-mount technology or SMT. This type of circuitry features smaller electrical components that mount directly to the face of the circuit board, resulting in reduced heat generation, enhanced performance under vibration conditions, maximum light intensity and maximum operating life. CURT converters are also fully tested, both optically and load-tested, to ensure reliable performance.
