All Hardware and Installation Instructions Included!
In the world of commercial towing, more is expected. A job cannot be completed if the equipment cannot handle the workload. That is why CURT developed the Commercial Duty class 5 trailer hitch. Constructed from steel and engineered for power, these class 5 hitches are designed to complement the towing power of full-size, commercial pickup trucks, including diesels and chassis cabs. They can easily handle a variety of oversize trailers, including toy and car haulers, livestock trailers, dumper trailers, large flatbed trailers, large boat trailers and more (NOTE: Never exceed the lowest weight capacity of any towing component). This particular class 5 hitch features a gross trailer weight capacity of 20,000 lbs. and a tongue weight capacity of 2,700 lbs. It is designed to be a custom trailer hitch for certain years of the Ford F250 Super Duty, F350 Super Duty and F450 Super Duty (to verify your vehicle compatibility, see application info). All CURT Commercial Duty class 5 hitches feature a 2-1/2" x 2-1/2" receiver tube opening to accept the strongest of ball mounts and towing accessories. They are perfect for mounting standard ball mounts, pintle mounts, tow hooks and weight distribution hitches as well as winch mounts and cargo carriers. CURT class 5 tow hitches are protected by a co-curing of liquid A-coat and carbide black powder coat finish. They also mount with grade-8 hardware, included with each hitch.
CURT custom wiring connectors and harnesses are the easiest way to outfit your vehicle with a trailer wiring connection for towing. Each one is custom-fitted to work with a specific make and model. This particular 7-way RV blade socket is designed to be a custom wiring option for certain years of the Ford F250 Super Duty, F350 Super Duty, F450 Super Duty and F550 Super Duty (see application info to verify fitment). It provides a universal trailer connection for the tail lights, brake lights, reverse lights, turn signals, electronic trailer brakes and auxiliary power. 7prong taillight wiring can be used as a replacement or new wiring and is typically used for towing fifth wheel and gooseneck trailers. This 7 way female outlet comes with all necessary hardware to establish a solid connection, as well as a dust cover to keep the connector socket clean when not in use. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this factory tow package 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. Instead of cutting, splicing and soldering into your vehicle's wiring system, the custom wiring connector uses a single OEM compatible plug and instantly provides a standard vehicle-to-trailer hitch wiring connection. To ensure long-lasting reliability, all CURT custom tconnector wiring is thoroughly tested for optimal functionality.
