All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Ford Flex and Lincoln MKT (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 400 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 4,000 lbs. WD and 400 lbs. WDTW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
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 Ford Flex (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 09 - 19 Ford Flex With dual exhaust Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13110 (Part #CHW-1226) fits 2009-2019 Ford Flex models. The 2019 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 09 - 19 Ford Flex With dual exhaust Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13110 (Part #CHW-1226) is designed to fit the 2009-2019 Ford Flex.
The 09 - 19 Ford Flex With dual exhaust Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13110 (Part #CHW-1226) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Curt 13110 is designed for Ford Flex, Flex Ecoboost, and Lincoln MKT models. The installation process is the same for all three, but note that Ford Flex Ecoboost and Lincoln MKT models have dual exhaust, so the installation steps must be repeated on both the driver and passenger sides.
No, drilling is not required. The hitch uses existing weld nuts on the vehicle and aligns with existing slots. The manual explicitly states 'NO DRILL' as an installation note.
You will need: a ratchet, 10" extension, 18mm and 19mm sockets, and a torque wrench. These tools are needed to remove the rubber isolators, remove the muffler hanger bracket, and torque the M12 fasteners to specification.
The kit includes 4 M12-1.75 x 40mm hex bolts and 4 conical toothed washers (1/2" size). These fasteners are used to secure the hitch to the existing weld nuts on the vehicle. The muffler hanger bracket bolts that you remove during installation should be returned to the vehicle owner.
The first step is to lower the exhaust by removing 3 rubber isolators. Support the exhaust as needed to prevent damage. A rubber isolator removal diagram is provided in the manual to guide this process.
Yes. Remove the muffler hanger bracket by removing its bolts (2 bolts). Keep these bolts and return them to the vehicle owner. On the driver side, the hanger bracket is then sandwiched between the hitch and the exhaust during final assembly.
Rotate the hitch into position above the exhaust and align the slots in the hitch with the existing weld nuts on the vehicle. The hitch uses these factory weld nuts for attachment, so proper alignment is essential before fastening.
The passenger side is secured using the existing weld nuts on the vehicle, along with the M12 hex head bolts and 1/2" conical toothed washers provided in the kit. All M12 fasteners are then torqued to 86 ft. lbs.
The driver side is sandwiched with the muffler hanger bracket and secured using the M12 hex head bolts and 1/2" conical toothed washers provided. The muffler hanger bracket sits between the hitch and the exhaust. All M12 fasteners are then torqued to 86 ft. lbs.
All M12 fasteners must be torqued to 86 ft. lbs. This applies to all four M12 hex head bolts used to secure the hitch.
The hitch weight is 85 lbs.
Professional installation takes approximately 39 minutes. DIY installation for a novice takes approximately 40 minutes.
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.
Alteration to, misuse of, or improper installation of the hitch voids the warranty. The warranty covers defects in material and workmanship at the time of retail purchase by the original purchaser. If a defect is found, Curt Manufacturing will repair or replace the product at their option.
Yes. When lowering the exhaust by removing the rubber isolators, you must support the exhaust as needed to prevent damage. Failure to do so could result in damage to the exhaust system.
After all M12 fasteners are torqued to 86 ft. lbs., raise the exhaust back into position. This completes the installation process.
No, the installation steps are the same for all three models (Ford Flex, Flex Ecoboost, and Lincoln MKT). However, because Ford Flex Ecoboost and Lincoln MKT models have dual exhaust, you must repeat the installation instructions for both the driver and passenger sides.

Yes, the Curt 56343 is designed for Ford Flex passenger cars. The harness connects at the driver and passenger side taillights inside the trunk.
The harness is rated for 3.0 amps per side for signal circuits and 6.0 amps total for tail/running circuits. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
You will need: a ratchet, 8mm socket, panel trim removal tool, wire stripper, wire crimper, and cutting tool. The manual also notes that a test light or properly wired trailer is needed to test the harness after installation.
The harness includes: a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black converter box, a provided screw for grounding, double-sided tape for mounting the converter box, a 4-flat connector with dust cover, and cable ties for securing loose wires.
Open the tailgate. Starting on the driver side, remove the two fasteners securing the taillight. Gently pull the taillight rearward to remove it, taking care not to damage the alignment tabs. Repeat on the passenger side.
Behind each removed taillight, locate the vehicle taillight wiring harness connectors. Separate them from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
You may use an existing screw with nut in the vehicle frame as a grounding point, or you can drill a 3/32" pilot hole for the provided screw. The grounding area must 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.
Mount the black converter box on a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Use the provided double-sided tape to adhere it. Mounting the box in a protected area is critical; failure to do so can cause loss of warranty, product failure, overheating and potential fire.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
Reinstall all items removed during installation. Install the provided 4-flat dust cover to help prevent corrosion. Test the harness for proper function using a test light or a properly wired trailer.
