When we came to the limits of towing capacity, we wanted to know what else was out there. What could we discover off the beaten path? So, we kept going. CURT class 5 Xtra Duty hitches begin a class of their own, beyond class 4 and beyond anything the standards dictate. They are designed for the hard road where only full-size pickup trucks, vans and SUVs dare to tread. They are capable of pulling almost any heavy-duty trailer, including toy haulers, dump trailers, logging trailers, small yacht trailers and more (NOTE: Never exceed the lowest weight capacity of any towing component). This particular Xtra Duty class 5 trailer hitch offers a gross trailer weight capacity of 17,000 lbs. and an extra-high tongue weight capacity of 2,550 lbs. It features a 2" x 2" receiver tube opening to accept a ball mount or hitch-mounted accessory, such as a cargo carrier or winch mount. It is designed to be a custom-fit trailer hitch for certain years of the Chevy Silverado 3500, 3500 HD or 3500 Classic, Dodge Ram 3500, 4500 or 5500, GMC Sierra 3500, 3500 HD or 3500 Classic and Ram 3500, 4500 or 5500 (to verify compatibility with your vehicle, see application info). For a little extra towing power and stability, this class 5 hitch can also be used in combination with a weight distributing hitch. It is rated for 17,000 lbs. WD and 2,550 lbs. WDTW. In our drive to create a more powerful hitch, CURT has not neglected the finer details. Our class 5 trailer hitches are welded with precision and go through multiple stages of cleaning to create a smooth surface that is ready to accept our co-cured finish. To protect them from corrosion, chipping and UV damage, these hitches are immersed in a liquid A-coat and then finished in a high-quality black carbide powder coat. They come with grade-8 mounting hardware for solid installation.
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 Chrysler Aspen and Pacifica, Dodge Dakota, Durango, Dodge Ram 2500, 1500 Van, 2500 Van, Dodge Sprinter 2500 and 3500, Jeep Commander, Grand Cherokee and Liberty and Mitsubishi Raider (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.

Yes. For Dodge chassis, remove the temporary license plate bracket and return bracket and hardware to the owner in Step 1. For Chevrolet/GMC models, this is also required on select models as part of Step 1a.
Yes, drilling is required. You must drill 3 holes on each side of the frame rail using a 25/32" drill bit. The hitch is used as a template to mark hole locations. On select GM models, you may need to enlarge existing holes instead of drilling new ones.
Yes. On all Dodge models, you must remove the rear-most rivet on the bottom of each frame rail. On select Chevrolet and GMC models, you must remove the rear-most rivet on the bottom of the frame rail approximately 3-1/2" from the end of the frame rails. Use a chisel and grinder to remove rivets.
On select Chevrolet and GMC models, you must remove the two rear-most fuel tank shield bolts from the frame rail and return the hardware to the owner. Support the fuel tank shield as necessary during this step. The hitch side plates will slide between the frame rail and fuel tank shield during installation.
All M16 hardware must be torqued to 195 ft-lbs. This applies to both Dodge and Chevrolet/GMC installations.
Raise the hitch into position and place the rear edges of the horizontal flanges flush with the end of the frame rails. Clamp the hitch to the frame rail before drilling.
You have two alignment options depending on your specific model: (a) Align the 1" diameter slot with the rivet on the bottom of the frame rail on each side and clamp in place, or (b) Align the rear-most rivet removed in Step 1c with the existing holes from Step 1b and clamp in place. The hitch side plates will slide between the frame rail and fuel tank shield. Choose the option that fits your application.
You must drill or enlarge 3 holes on each side of the frame rail, for a total of 6 holes. On select GM models, this includes holes in the fuel tank shield tab. Use the hitch as a template to mark hole locations.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This helps maintain safe operation and extends the life of the hitch.
No. You must not exceed your vehicle manufacturer's recommended towing capacity, even though the hitch is rated for 17,000 lbs. trailer weight and 2,550 lbs. tongue weight. Always follow your vehicle's towing limits.

Part 55381 fits Dodge Ram 1500, 2500, and 3500 models equipped with a factory 7-way connector. If your vehicle has the factory 7-way connector, this harness is compatible. Vehicles without the factory 7-way connector are not supported by this product.
Yes, part 55381 is compatible with Jeep Grand Cherokee models that have a factory 7-way connector. The harness is designed to work with the factory 7-way connector on this vehicle.
Yes, part 55381 fits Dodge Sprinter 2500 and 3500 models, as well as Freightliner Sprinter 2500 and 3500 models, provided they have a factory 7-way connector.
Yes. The 55381 custom wiring harness is designed to work only with vehicles equipped with a factory 7-way connector. The harness is inserted between the factory 7-way connector and the vehicle wiring harness. Vehicles without a factory 7-way connector cannot use this product.
The 55381 is a custom wiring harness that connects between your vehicle's factory 7-way connector and the vehicle wiring harness. It allows you to use aftermarket trailers and towing equipment with your vehicle's existing electrical system.
The manual does not specify any special tools required. The installation involves locating the factory 7-way connector under the driver side bumper, removing mounting screws or bolts, separating connectors by pressing a red locking tab, and reinstalling components. Standard hand tools for removing fasteners should be sufficient.
The factory 7-way connector is located under the bumper on the driver side of the vehicle, near the taillight wiring harness. The exact location varies by vehicle type: on SUVs, vans and pickup trucks, look behind the driver side taillight housing (location S1 for SUVs/vans, T1 for pickup trucks).
Carefully press the red locking tab on the connector sideways and pull the connectors apart. Take care not to damage the locking tabs during this process. Once separated, ensure the mating surfaces of both connectors are free of dirt and clean if necessary before proceeding.
Insert the custom wiring harness between the separated factory 7-way connector and vehicle wiring harness. Make sure both connectors are fully inserted with locking tabs in place. Push the red locking tabs back to their original position to secure the connection.
Reinstall all items you removed during installation. Install the provided 4-flat dust cover to help prevent corrosion of the connectors.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating.
Before drilling to avoid damage and personal injury, check for miscellaneous items that may be hidden behind or under any surface. However, the standard installation of the 55381 does not require drilling—it is a connector-based installation.
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 will function properly.
The 55381 fits Chrysler Aspen and Pacifica, Dodge Dakota, Durango, Ram 1500/2500/3500, Ram vans, and Sprinter vans, Freightliner Sprinter vans, Jeep Commander, Grand Cherokee, and Liberty, and Mitsubishi Raider—all with factory 7-way connectors. Check your vehicle's documentation to confirm it has a factory 7-way connector.
No. The 55381 is a connector-based installation that requires no drilling, cutting, or permanent modifications. It connects between your factory 7-way connector and vehicle wiring harness.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause overheating and fire. Check your vehicle owner's manual for the tow vehicle lamp load rating.
Test for proper function using a test light or by connecting a properly wired trailer. Ensure all installation steps have been completed.
