All Hardware and Installation Instructions Included!
Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Mazda CX-9 (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Mazda CX9 (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The 16 - 23 Mazda CX-9 Curt 1-1/4" Class 2 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 12156 (Part #5W-CHW-2281) fits the following vehicles: 2016-2023 Mazda CX-9. Always verify your specific year, make, and model before ordering.
The 16 - 23 Mazda CX-9 Curt 1-1/4" Class 2 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 12156 (Part #5W-CHW-2281) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the CURT 12156 is designed for 2016-current Mazda CX-9 SUVs. Before purchasing, verify your vehicle matches this year range and model. The hitch is a weight-carrying type with a maximum trailer weight capacity of 3500 lbs and tongue weight capacity of 350 lbs.
The CURT 12156 is rated for a maximum trailer weight of 3500 lbs and a tongue weight of 350 lbs when used as a weight-carrying hitch. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
The CURT 12156 is designed for use with ballmount #45521. Euro mount options are also available: #45571 (1 7/8" ball) or #45572 (2" ball).
You will need: a ratchet, 10mm and 3/4" sockets, a 6" socket extension, a torque wrench, a flathead screwdriver, and safety glasses. The manual also references exhaust removal pliers or an equivalent method for removing rubber exhaust hangers.
No. The CURT 12156 is a no-drill application. It uses existing holes in the frame rails and access holes for installation.
Two people may be required to ease installation. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
Safety glasses must be worn at all times while installing this product. When removing the exhaust hangers, make sure the exhaust is properly supported before proceeding with installation.
All 1/2" fasteners must be torqued to 110 ft-lbs. This is the final step after the hitch is raised into position and secured with the 1/2" hex flange nuts.
The hitch includes: 4 carriage bolts (1/2-13 UNC, 1-1/2", grade 8, part 10-10287), 4 serrated flange nuts (1/2-13 UNC, grade 8, part 20-00062), 4 square hole spacers (0.250 x 1.00 x 3.00", part CM-SP6), and 4 pieces of 1/2" fishwire (part 1_2 FISHWIRE).
Fishwire is used to guide bolts and spacers through the frame rail access holes. In step 3, you thread one 1/2" carriage bolt and one CM-SP6 spacer through the access hole and into the forward-most hole in each frame rail, leaving the fishwires attached. In step 4, you reverse fishwire one bolt and spacer through the access hole in each frame rail, again leaving fishwires attached. When raising the hitch into position in step 5, you guide the fishwire ends through the attachment holes, then remove the fishwires and secure the hitch with hex flange nuts.
You must remove the four rubber exhaust hangers to access the installation area. The exhaust itself does not need to be fully removed, but it must be supported while the hangers are removed. After the hitch is installed and torqued, you raise the exhaust back into position and reinstall the exhaust hangers.
Yes. The first installation step is to remove the lower trim panel from the vehicle by removing two plastic fasteners using a flathead screwdriver and two hex nuts using a 10mm socket. The trim panel should be returned to the vehicle owner after installation.
All non-trailer (wheel-less) loads applied to this hitch must be supported by 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. For further information about stabilizing straps, see the CURT catalog or visit www.curtmfg.com.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.

The Curt 56338 is a custom wiring connector that provides a 4-flat trailer connector interface for your Mazda CX-9. It includes a black converter box that mounts behind the side trim panel and allows you to connect a trailer or towed vehicle.
The Curt 56338 has the following electrical ratings: signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.

Insert the custom connector end into the vehicle connector, ensuring the connectors are fully inserted with the locking tabs in place. The custom connector is designed to match the vehicle connector, so alignment should be straightforward.
Mount the black converter box on a flat spot behind the side trim panel using the double-sided tape provided with the connector. Secure any loose parts of the wiring connector with the provided cable ties.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent damage and maintain a clean appearance.
Test the connector for proper function by using a test light or by connecting a properly wired trailer. All connections must be complete for the harness to function properly. For the initial test, reset the electrical system by temporarily removing the vehicle key from the ignition.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating, and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
