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 Express 1500, 2500 or 3500 and GMC Savana 1500, 2500 or 3500 (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 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 Express and GMC Savana 1500, 2500 and 3500 (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 Curt 13040 receiver hitch is designed for Chevy/GMC full-size vans including the Savannah and Express models. Confirm your vehicle matches this description before purchasing. The manual does not list specific model years or exclude any variants within this category.
No. The manual explicitly states "NO DRILLING REQUIRED." The hitch uses existing holes in the vehicle frame for installation.
The kit includes 6 square hole spacers (CM-SP1, 0.250 x 1.50 x 2.00"), 6 Grade 8 bolts (1/2-13 UNC, 1-3/4" long, part 10-10272), and 6 Grade 8 serrated flange nuts (1/2-13 UNC, part 20-00062). All fasteners are Grade 8 and zinc-plated.
Torque all fasteners to 110 lb-ft using a torque wrench.
1. Raise the hitch into position. 2. Using existing holes in the frame, place 1/2" bolts and spacers through the access slots and into the hitch through the holes in the frame. 3. Tighten with 1/2" flange nuts. 4. Torque all fasteners to 110 lb-ft.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an exact interval; regular inspection before towing is recommended.

Yes, Curt part number 55240 is designed for Chevrolet Express and GMC Savana vehicles. The harness connects to your vehicle's factory tow harness connector, which should be located behind the rear doors.
The factory tow harness connector is located behind the rear doors of your Chevrolet Express or GMC Savana. Open the rear doors and remove the jack storage cover to access it. The connector will have connection points similar to those on the tow harness you are installing.
1. Open the rear doors and remove the jack storage cover. 2. Locate the vehicle's factory tow harness connector. 3. Insert the tow harness into the vehicle's connector, ensuring the connectors are fully inserted with locking tabs in place.
The locking tabs are part of the connector design that secure the tow harness to the vehicle's factory connector. When you insert the harness, push it in fully until you hear or feel the locking tabs engage. This ensures a secure, reliable connection.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. Secure the white wire using the eyelet and screw provided with the harness. If no suitable existing screw is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided.
Drilling is required only if no suitable existing grounding point (such as a screw with nut in the vehicle's frame) is available near the connector. If you must drill, make a 3/32" hole and secure the white wire using the eyelet and screw provided.
Drill a 3/32" hole for the ground wire eyelet.
Before drilling, verify that miscellaneous items hidden behind or under any surface are not in the way. Drilling into hidden components can cause damage and/or personal injury.
Route the 4-flat wire to the center of the vehicle and out the rear doors when in use. When not in use, roll up the wire and store it in an out-of-the-way location in the jack storage compartment.
The harness includes an eyelet and screw for securing the white ground wire to the vehicle's frame.
