When we came to the limits of towing capacity, we wanted to know what else was out there. What could we discover off the beaten path? So, we kept going. CURT class 5 Xtra Duty hitches begin a class of their own, beyond class 4 and beyond anything the standards dictate. They are designed for the hard road where only full-size pickup trucks, vans and SUVs dare to tread. They are capable of pulling almost any heavy-duty trailer, including toy haulers, dump trailers, logging trailers, small yacht trailers and more (NOTE: Never exceed the lowest weight capacity of any towing component). This particular Xtra Duty class 5 trailer hitch offers a gross trailer weight capacity of 17,000 lbs. and an extra-high tongue weight capacity of 2,550 lbs. It features a 2" x 2" receiver tube opening to accept a ball mount or hitch-mounted accessory, such as a cargo carrier or winch mount. It is designed to be a custom-fit trailer hitch for certain years of the Ford F350 Super Duty, F450 Super Duty and F550 Super Duty (to verify compatibility with your vehicle, see application info). For a little extra towing power and stability, this class 5 hitch can also be used in combination with a weight distributing hitch. It is rated for 17,000 lbs. WD and 2,550 lbs. WDTW. In our drive to create a more powerful hitch, CURT has not neglected the finer details. Our class 5 trailer hitches are welded with precision and go through multiple stages of cleaning to create a smooth surface that is ready to accept our co-cured finish. To protect them from corrosion, chipping and UV damage, these hitches are immersed in a liquid A-coat and then finished in a high-quality black carbide powder coat. They come with grade-8 mounting hardware for solid installation.
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 setup. 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 vehicle's electrical system and provides a standard 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 harness provides a 7-way RV blade connector socket and is designed to be a custom wiring harness for certain years of the Ford F-250, F-350, F-450, F-550, F-650 Super Duty (see application info to verify fitment). 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.

Yes, drilling is required. You must drill mounting holes in the vehicle frame using a 17/32" drill bit. The manual specifies that you mark the hole furthest from the bumper first, then drill. A metal or wood shield must be placed between the frame and fuel tank, fuel filler hose, or electrical wires to prevent damage during drilling.
When drilling the hitch mounting holes, you must use a metal or wood shield between the frame and fuel tank, fuel filler hose, or electrical wires to prevent damage when the frame is drilled through.
1. Raise the hitch into position and clamp it in place, using the rivet clearance holes in the side plates for proper alignment. 2. Mark the hole furthest from the bumper for drilling, then drill using a 17/32" drill bit. 3. Fasten the hitch to the frame, fastening to the drilled holes in the back of the frame first, then to the drilled holes in the front. 4. Attach the mounting plates to the hitch and fasten to the truck. 5. Torque all hardware to 110 ft-lbs.
All hardware must be torqued to 110 ft-lbs.
A 17/32" drill bit is required to make the mounting holes in the vehicle frame.
Do not exceed your vehicle manufacturer's recommended towing capacity. The manual emphasises this as a critical safety requirement.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound.

Part 56443 is designed for trucks with factory connectors located on the driver-side frame rail or rear-most cross member. Check your vehicle's frame rail and rear cross member for existing connectors that match the appearance of those shown in the manual. If your truck has these factory connectors, the harness is compatible. If you cannot locate matching connectors, your vehicle may not be equipped for this product.
Part 56443 is a custom wiring harness that connects to a 7-way RV blade connector for trailer lighting and braking functions. It routes from the vehicle's factory connectors to a round USCAR plug that mounts to the vehicle, allowing you to connect a trailer with compatible wiring.
You need a flathead screwdriver. Cable ties are also recommended to secure loose wires during routing. A test light, 7-way RV blade tester, or functioning trailer is required to verify proper function after installation.
Yes. Before beginning installation, locate your vehicle's battery in the engine compartment (typically on the passenger side for most gas engines, and on both sides for some gas engines and all diesel engines) and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation.
The factory connectors are located on the driver-side frame rail or the rear-most cross member of your vehicle. They will resemble the connectors included with your new custom wiring harness. Separate these connectors from their dust covers carefully, taking care not to damage the locking tabs.
Route the harness to the 7-way mounting location on your vehicle. Install the round USCAR plug into the 7-way RV blade connector and mount it to the vehicle. Use cable ties as needed to secure any loose wires along the route. Once mounted, reconnect the negative battery terminal if it was disconnected.
After connecting the 12-volt power wire to the harness and reconnecting the battery, verify that the harness is functioning by attaching the battery and testing with a test light, 7-way RV blade tester, or a functioning trailer. This confirms all connections are working properly before towing.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Consult your vehicle's owner's manual and the product documentation for the specific rating of part 56443.
If your vehicle is not factory equipped with trailer brakes, you must consult your vehicle's owner's manual to verify that your vehicle can utilize components and wiring for the trailer braking function. The owner's manual will also specify any fuses that need to be installed. Do not assume your vehicle supports trailer braking without checking the owner's manual first.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Regular maintenance helps prevent electrical failures and ensures safe trailer operation.
The manual provides a wiring location guide for trucks with five reference points: T1 (behind driver side taillight housing), T2 (behind passenger side taillight housing), T3 (behind driver side rear bumper), T4 (behind center of rear bumper fascia), and T5 (behind passenger side rear bumper). These locations help you route the harness correctly during installation.
Part 56443 fits trucks with factory connectors on the driver-side frame rail or rear-most cross member. Check your vehicle for these connectors before purchasing.
You need a flathead screwdriver, cable ties, and a test light or 7-way RV blade tester to verify function after installation.
Yes, disconnect the negative battery terminal before starting installation. Fasten the wire down and away from the battery during the installation process.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. If your vehicle lacks factory trailer brakes, verify in the owner's manual that your vehicle can use trailer braking components.
