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 F150, F150 Heritage, F250, F250 Super Duty and F350 Super Duty (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 6,000 lbs. GTW and 600 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 10,000 lbs. WD and 1,000 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.
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.
