All Hardware and Installation Instructions Included!
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.
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 GMC C1500, C2500, C3500, K1500, K2500 and K3500 (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.

The Curt 55315 kit includes a custom wiring harness with a yellow wire connector end, a white ground wire with ring terminal, a provided screw for grounding, cable ties for securing loose wires, and a 4-flat dust cover to help prevent corrosion.
The manual lists no specific tools as required. However, you will need a drill to create a 3/32" pilot hole for the ground wire screw if a suitable existing screw with nut is not available on the vehicle frame. A test light or properly wired trailer is needed to test for proper function after installation.
The manual does not specify whether the battery must be disconnected. Check your vehicle owner's manual or contact the vehicle manufacturer for guidance on electrical work preparation.
Locate your vehicle's taillight wiring harness connector. Separate the connector from the taillight housing carefully, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors. Push both connectors fully together until the locking tabs are in place and secure.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. The area must be free of rust, dirt and paint. If no suitable point exists, drill a 3/32" pilot hole and use the provided screw. Secure the white ground wire using the ring terminal and the provided screw.
Drilling is required only if a suitable existing screw with nut is not available on the vehicle frame near the taillight connector for grounding. If drilling is necessary, you will drill a 3/32" pilot hole. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll up the connector and store it in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or connecting a properly wired trailer to the 4-flat connector. All steps must be followed to ensure the wiring harness will function properly. If testing reveals issues, review the installation steps to confirm all connections are secure and the ground wire is properly attached.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire. Refer to your vehicle owner's manual or contact the vehicle manufacturer for your specific lamp load rating.
Install the provided 4-flat dust cover to help prevent corrosion. This should be done as part of the final installation step after all other components are in place.
No, you do not need to remove the taillight housing. You only need to separate the taillight wiring harness connector from the housing by carefully disconnecting it, taking care not to damage the locking tabs. The custom harness is then inserted between the separated connectors.
