Trailer Hitch
Whatever the next item is on your to-do list -- whether it's arriving at the jobsite before dawn or getting your travel trailer set up in time to see the sunset -- CURT class 4 trailer hitches offer greater towing power to let you Bring It. These custom receiver hitches are built to tackle bigger jobs and bolder adventures, all while giving you a custom fit for your vehicle. Class 4 hitches are available for a variety of makes and models, from pickup trucks and SUVs to full-size and commercial vans. This particular class 4 hitch fits certain years of the Chevy C30, C3500, C3500HD or Silverado 3500, Ford F Super Duty, F350, F350 Super Duty, F450 Super Duty or F550 Super Duty and GMC C3500, C3500HD or K3500 (to verify vehicle compatibility, see application info). It provides a weight carrying capacity of 10,000 lbs. GTW and 1,000 lbs. TW. It can also accept a weight distributing hitch, offering a maximum WD capacity of 12,000 lbs. and a WDTW of 1,200 lbs. CURT class 4 tow hitches are as much suited for work as they are for play. With their high load capacities, they are typically used for towing larger trailers, including everything from a double-axle utility trailer or livestock trailer to a full-length camper or large boat trailer (NOTE: Never exceed the lowest weight capacity of any towing component). All CURT class 4 receiver hitches come with a 2" receiver tube opening and all the necessary hardware for a complete installation. From light-duty to heavy-duty, every CURT custom hitch is engineered to be vehicle-specific, using actual vehicles to create the optimal design. We then combine high-strength steel, precise welding and a co-cured finish of liquid A-coat and durable black powder coat to provide you with a hitch you can depend on. To prove it, we test all our hitches in accordance with SAE J684 for safety.

Vehicle 4 Way Converter
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 Chevy Blazer, K5 Blazer, C10, C20, C30, K10, K20 and K30 pickup or Suburban and GMC C15, C1500, C25, C2500, C35, C3500, K15, K1500, K25, K2500, K35 and K3500 pickup or Suburban (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.

Nall Mount w/ Ball
When it comes to ball mounts, a CURT loaded ball mount is the complete package. These stingers come with all necessary towing components and are pre-fitted with a factory-torqued trailer ball, eliminating the need to mount and torque your own trailer ball.

This ball mount also has a length of 7-1/2", a drop of 2" and comes with a gloss black powder coat finish to resist rust, chipping and UV damage.
