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 Express 1500, 2500 or 3500 and GMC Savana 1500, 2500 or 3500 (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 Chevy Express and GMC Savana 1500, 2500, 3500 and 4500 (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 14090 is designed for Chevy/GMC Van Savana/Express full-size models. Confirm your vehicle matches this description before purchasing. The manual does not specify model years, so contact Curt Manufacturing or your dealer to verify fitment for your specific year and configuration.
The Curt 14090 has a gross load capacity of 10,000 lbs. trailer weight and 1,000 lbs. tongue weight when used as a weight-carrying hitch, or 12,000 lbs. trailer weight and 1,200 lbs. tongue weight when used as a weight-distribution hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The hitch weight is 49 lbs.
The kit includes 6 carriage bolts (1/2"-13 UNC, 1-3/4" long, Grade 8, yellow zinc), 6 flange nuts (1/2"-13 UNC, Grade 8, yellow zinc), and 6 square hole spacers (0.250" × 1.50" × 2.00"). All fasteners are Grade 8 and yellow zinc plated.
No. The Curt 14090 uses existing frame holes and requires no drilling. The installation notes explicitly state "NO DRILLING REQUIRED."
All fasteners must be torqued to 110 lb.-ft. This applies to all six 1/2" carriage bolts and flange nuts used to attach the hitch to the frame.
1. Raise the hitch into position. 2. Using existing frame slots, insert a 1/2" carriage bolt and spacer through each frame hole into the hitch. 3. Fasten using a 1/2" flange nut. 4. Torque all fasteners to 110 lb.-ft. No drilling is required; the hitch uses existing frame holes.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify a retorque interval or maintenance schedule beyond this general inspection.
Do not exceed your vehicle manufacturer's recommended towing capacity. The hitch itself can handle up to 10,000 lbs. (weight-carrying) or 12,000 lbs. (weight-distribution), but your vehicle may have a lower limit that must be respected.

Yes, the Curt 55540 is designed for Chevrolet Express 1500, Express 2500/3500, GMC Savana 1500, and Savana 2500/3500 models. It is compatible with SUVs, mini and full-sized vans in the S category.
The Curt 55540 is a custom wiring harness that integrates with your vehicle's taillight wiring to enable trailer lighting functions. It connects between the vehicle's taillight connectors and allows you to control trailer lights through your vehicle's lighting system.
Yes, you must disconnect the negative battery terminal before beginning installation. Reconnect it only after all installation steps are complete and all trim panels have been reinstalled.
You will need a ratchet and a 10mm socket. A drill may be required if a suitable existing grounding point is not available on your vehicle frame.
You must remove the rear trim fascia and interior trim panels near the rear entry doors on both the driver and passenger sides. The harness routes behind these panels to access the taillight connectors.
Locate the vehicle's taillight wiring harness connectors near the rear entry doors. Separate the connectors from the taillight housing carefully to avoid damaging the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. If no suitable existing point is available, drill a 3/32" pilot hole for the provided screw.
Drilling is required only if a suitable existing grounding point is not available on your vehicle frame. If needed, you will drill a 3/32" pilot hole for the provided grounding screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Route the custom wiring harness end with the green wire to the passenger side behind the removed trim panels. Enough wire has been provided to route the wire either under the threshold plate or above the rear cargo doors. Tuck the green wire under the floor trim panel before reinstalling the rear trim panels.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
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.
The provided 4-flat dust cover should be installed to help prevent corrosion of the trailer connector. Install it after reconnecting the negative battery terminal and reinstalling all removed items.
No, you must remove the rear trim fascia and interior trim panels near the rear entry doors to access the taillight wiring connectors on both sides of the vehicle. These panels must be removed to properly connect the harness.
