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 Dodge Sprinter 2500 and 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.
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.

The 13250 spacer plate fits 03-06 Dodge and Freightliner Sprinter Vans, but not the 140" dual wheel model. If you have a 118" wheelbase vehicle, you will need to relocate the spare tire and modify the exhaust hanger. If you have a 158" wheelbase vehicle, you must remove the step bumper support brace from the passenger side step bumper bracket. Confirm your exact wheelbase and wheel configuration before purchasing.
No. The manual explicitly states this product will not fit the 140" dual wheel Sprinter model.
Only if your Sprinter Van has a 118" wheelbase. The manual states that 118" wheelbase vehicles need to have the spare relocated and the exhaust hanger modified. Other wheelbase vehicles do not require spare tire relocation.

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.
