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 F350 Super Duty, F450 Super Duty, F550 Super Duty and F650 (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 Bonderite and carbide black powder coat finish. They also mount with grade-8 hardware, included with each hitch.
