All Hardware and Installation Instructions Included!
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 Mazda 3 (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.
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 Mazda 3, 6 and CX7 and Toyota Camry, Corolla and FJ Cruiser (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.

The 14 - 18 Mazda 3 Sedan Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11377 (Part #CHW-2222) fits the following vehicles: 2014-2018 Mazda 3. Always verify your specific year, make, and model before ordering.
Yes, the 14 - 18 Mazda 3 Sedan Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11377 (Part #CHW-2222) is designed to fit the 2014-2018 Mazda 3.
The 14 - 18 Mazda 3 Sedan Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11377 (Part #CHW-2222) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, part number 11377 is designed for 2014 Mazda Mazda3 in both sedan and hatchback body styles. The installation procedure differs slightly between the two: hatchback models require temporary exhaust lowering, while sedan models require bumper trim.
The hitch is rated for a maximum of 2,000 lbs trailer weight and 200 lbs tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Non-trailer (wheel-less) loads applied to this hitch must be supported by Curt part number 18050 Stabilizing Straps. Failure to properly support non-trailer loads will void the product warranty. Contact Curt or check their website for information on the 18050 straps.
Required tools include: safety glasses, torque wrench, ratchet, 3/4" socket, socket extension (6"), tape measure, masking tape, and aviation shears. A torque wrench is essential because all 1/2" fasteners must be torqued to 110 lb-ft.
No, drilling is not required. The hitch uses existing frame rail attachment points and a fishwire fastening technique to route bolts through the frame.
Two people may be required to ease installation, though the manual does not state this is mandatory. If you are hesitant to undertake the task alone, Curt recommends contacting an authorized installer.
Bumper trimming is required only on sedan models. The lower bumper cover must be trimmed on both sides as shown in the installation diagram. Hatchback models do not require bumper trimming.
Exhaust lowering is required only on hatchback models. Remove the four rubber isolators from the muffler to lower the exhaust temporarily during installation, then raise it back into position and reinstall the isolators after the hitch is mounted. Sedan models do not require this step.
Fishwire is a technique to route bolts through frame rail attachment holes without drilling. Remove masking tape from the forward attachment point and thread the supplied 1/2" fishwire through the frame holes. Attach the two forward carriage bolts and spacers to the fishwire on both sides, then pull them through. Reverse-pull the two rearward bolts and spacers into the rear holes. Leave the wires on temporarily while raising the hitch, then remove them and install the hex flange nuts.
All 1/2" fasteners must be torqued to 110 lb-ft. This is the final step after the hitch is raised into position and all nuts are loosely installed.
The kit includes: four 1/2" fishwires, four 0.250 x 1.00 x 3.00" square hole spacers (part CM-SP6), four 1/2-13 UNC carriage bolts, 1-1/2" long, Grade 8 (part 10-10287), and four 1/2-13 UNC serrated flange nuts, Grade 8 (part 20-00062).
After installation, periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This maintenance is important for safe operation.
The hitch is designed for use with Curt Euro mount ball options: part number 45571 (1 7/8" ball) and part number 45572 (2" ball). It is also compatible with part numbers D-21 and 45521.
