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 Chevy Equinox (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,500 lbs. GTW and 675 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 4,500 lbs. WD and 675 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 are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special 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. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Chevy Equinox (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The hitch weight is 30 lbs.
Required tools are: ratchet, 15 mm and 3/4" sockets, 6" socket extension, T15 Torx bit socket, pry bar, torque wrench, rotary tool, and safety glasses. Proper tools greatly improve installation quality and reduce installation time.
The hitch includes: 6 carriage bolts (1/2-13 UNC, 1-1/2", Grade 8, part number 10-10287), 6 serrated flange nuts (1/2-13 UNC, Grade 8, part number 20-00062), 6 square hole spacers (0.250 x 1.00 x 3.00", part number CM-SP6), and 6 pieces of 1/2" fishwire (part number 1_2 FISHWIRE).
No drilling is required. The hitch uses existing frame rail access holes. However, you must slightly enlarge the access holes on both the driver and passenger side frame rails to allow the hardware to fit.
Yes. You must slightly enlarge the access holes on both the driver and passenger side frame rails to allow the hardware to fit. The manual indicates the access hole diameter is approximately 1.08". Use a rotary tool to enlarge the holes. This is a permanent modification to the vehicle frame.
Yes. The exhaust must be temporarily lowered during installation. Remove the 4 bolts from the rear exhaust hanger brackets (2 per side) using a 15 mm socket, then remove the exhaust rubber isolator in front of the muffler. Be sure to support the exhaust during this process. After hitch installation is complete, reinstall the exhaust.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and notes that using proper tools will greatly improve the quality of the install and reduce the time required. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
Professional installation time is approximately 60 minutes. Novice (DIY) installation time is approximately 45 minutes. Actual time may vary depending on experience and familiarity with the vehicle.
The first step is to locate and remove the 2 Torx screws from the rear fascia. Save these screws for reinstallation at the end of the installation process.
After enlarging the access holes on both frame rails, utilize the access hole to fishwire one 1/2" carriage bolt and one spacer into each of the three mounting holes in both frame rails. This allows you to position the bolts through the frame without fully inserting them, making it easier to align the hitch before final tightening.
Raise the hitch into position and secure it to the vehicle using 6 of the 1/2" hex flange nuts (part number 20-00062) included with the hitch. Each nut fastens one of the carriage bolts that was previously fishwired into the frame rails.
Torque all 1/2" hardware to 110 ft-lb. Use a torque wrench to ensure proper tightening. After installation, periodically check that all fasteners remain tight.
After torquing the 1/2" hardware to 110 ft-lb, reinstall the exhaust and the 2 Torx fascia screws that were removed in step 1. This completes the installation.
After installation, verify that all fasteners are tight and all structural components are sound. The manual recommends periodically checking the receiver hitch to ensure all fasteners remain tight and all structural components remain in good condition throughout the life of the hitch.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. The manual does not specify an exact interval, but regular inspection is recommended to maintain safe operation.

The connector includes relays that must be installed in the vehicle's fuse panel (positions K2 and K3) to manage signal and tail/running light circuits.
Yes, the Curt 56375 is designed for Chevrolet Equinox SUVs, Mini & Full-Sized Vans (S). The connector mounts behind the center of the rear bumper. If you have a different vehicle model or year, contact the manufacturer or consult a fitment database to confirm compatibility.
You need a flat blade screwdriver and a cutting tool. The screwdriver is used to remove the fuse panel cover, and the cutting tool may be needed during installation. The manual does not specify additional tools or whether professional installation is recommended.
The kit includes the custom wiring connector, two relays (for installation in fuse panel positions K2 and K3), a 4-flat dust cover, and cable ties for securing loose wires.
The vehicle wiring connector is located along the rear bumper, behind the center. It will be similar in appearance to the custom wiring connector included in the kit. You will separate this connector from the weather seal connector as the first step of installation.
1. Locate the vehicle wiring connector along the rear bumper. 2. Carefully separate the vehicle connector from the weather seal connector, taking care not to damage the locking tabs. 3. Insert the custom wiring connector end into the vehicle connector. 4. Ensure the connectors are fully inserted with locking tabs in place. The connectors must be fully seated for proper function.

On the driver side, locate the fuse access panel cover on the side trim. 3. Remove the fuse panel cover. 4. Install the relays in positions K2 and K3 as shown on the fuse cover. 5. Reinstall the fuse panel cover.
When in use, route the 4-flat out from the vehicle. When not in use, roll it up and store it in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent damage and maintain a neat appearance.
The provided 4-flat dust cover helps prevent corrosion of the connector. Install it after the custom wiring connector is fully connected to the vehicle connector. The manual does not provide specific installation details beyond this instruction.
