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 Infiniti Q50 (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 Infiniti Q50 (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.

Yes, the 14 - 24 Infiniti Q50 Excluding Sport Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11407 (Part #CHW-1917) is designed to fit the 2014-2024 Infiniti Q50.
The 14 - 24 Infiniti Q50 Excluding Sport Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11407 (Part #CHW-1917) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the CURT 11407 is designed for 2014-Present Infiniti Q50 Sedan models. Before purchasing, verify your vehicle matches this specification and that you have access to the frame rails on both driver and passenger sides, as the installation requires routing hardware through existing holes in the frame.
The CURT 11407 is designed for use with ball mount 45521. Euro mount options are also available: 45571 (1 7/8" ball) or 45572 (2" ball). Consult the CURT catalog or website to confirm which mount suits your towing needs.
The CURT 11407 has a gross load capacity of 2,000 lbs trailer weight and 200 lbs tongue weight when used as a weight-carrying hitch. You must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these figures.
Required tools are: ratchet, torque wrench, 11/16" socket, 12mm socket, socket extension, die grinder, and safety glasses. The die grinder is essential for enlarging the access holes in the frame to allow the carriage bolts and spacers to pass through.
Two people may be required to ease installation. The manual rates this as a moderate to challenging installation. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance. Technical support is available at 877.287.8634.
No, you do not need to remove the exhaust system completely. Step 1 requires you to temporarily lower the exhaust by removing 6 bolts from the muffler brackets. Retain these bolts for reinstallation. After the hitch is installed, re-attach the muffler brackets and torque all M8 muffler bracket hardware to 23 ft-lbs.
No drilling is required. However, you must enlarge the existing access holes in the frame using a die grinder to allow the 7/16" carriage bolts and spacers to pass through. The manual does not specify the exact enlarged hole dimensions, so consult the product diagram or contact CURT technical support at 877.287.8634 for precise measurements.
Torque all 7/16" hardware (carriage bolts and flange nuts) to 59 ft-lbs. After re-attaching the muffler brackets, torque all M8 muffler bracket hardware to 23 ft-lbs. Use a calibrated torque wrench to ensure proper fastener tension.
Fishwire is a routing technique to guide the 7/16" carriage bolts and CM-SP7 spacers through the enlarged access hole and out the existing holes in the side of the frame rail. Thread the fishwire through the enlarged hole, attach the bolts and spacers to the fishwire, then pull the fishwire to draw the hardware through. Leave the fishwires attached during this process to prevent loss of hardware into the frame rails. Push the carriage bolts back into the frame rail before raising the hitch into position.
The kit includes: 4 pieces of 7/16" fishwire, 4 grade-8 7/16"-14 UNC carriage bolts (1-1/2" long, part 10-10282), 4 grade-8 7/16"-14 UNC flange nuts (part 20-00103), and 4 square hole spacers (0.250 x 1.00 x 2.00", part CM-SP7). All fasteners are grade 8 and must be torqued to 59 ft-lbs.
Safety glasses must be worn at all times during installation. Before beginning, read all instructions thoroughly. If you are hesitant to undertake this task, contact an authorized CURT installer. After installation, periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound.
All non-trailer (wheel-less) loads applied to this product must be supported by 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. See the CURT catalog or visit www.curtmfg.com for further information on stabilizing straps.
After installation, verify that all 7/16" fasteners are torqued to 59 ft-lbs and all M8 muffler bracket fasteners are torqued to 23 ft-lbs. Periodically check the receiver hitch to ensure all fasteners remain tight and all structural components are sound. This ongoing maintenance is essential for safe towing.
The manual requires periodic checks to ensure all fasteners are tight and all structural components are sound. While a specific interval is not stated, regular inspection before towing is recommended. If fasteners become loose, re-torque all 7/16" hardware to 59 ft-lbs and all M8 muffler bracket hardware to 23 ft-lbs.

Yes, the Curt 56248 is designed for the Infiniti Q50. The harness connects to the vehicle's taillight wiring connectors located behind the taillight housings inside the trunk.
The harness is rated for 3.0 amps per side for signal circuits and 6.0 amps total for tail and running circuits. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
You will need a panel trim removal tool and a flat blade screwdriver. If you need to create a grounding point, you will also need to drill a 3/32" pilot hole.
Yes. Step 1 requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before beginning installation.
The taillight wiring connectors are located behind the taillight housings inside the trunk. You will find them by pulling back the felt liner after removing the trunk floor coverings and scuff panel. The connectors are T-connector style, similar to the custom wiring harness connectors.
Separate the vehicle's taillight wiring connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end with the green wire between the separated connectors on the passenger side, and the end with the yellow wire on the driver side. Make sure the connectors are fully inserted with locking tabs in place.
Drilling is optional. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no existing screw is available, you may drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame, or drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and the provided screw.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
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 tow vehicle lamp load rating, whichever is lower.
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.
Reinstall all items removed during installation and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
