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 Ram 1500 and Dodge Ram 1500 (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 Lincoln MKZ (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.

Part number 13374 is designed for Dodge Ram 1500 without OEM hitch. If your vehicle already has a factory-installed hitch, this product is not compatible. Verify your vehicle does not have an OEM hitch before purchasing.
The hitch weight is 60 lbs.
When used as a weight-carrying hitch, the gross load capacity is 6,000 lbs. trailer weight and 600 lbs. tongue weight. When used as a weight-distribution hitch, the gross load capacity is 10,000 lbs. trailer weight and 1,000 lbs. tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
No. Part 13374 is designed for Dodge Ram 1500 without OEM hitch only.
No drilling is required. The hitch uses existing frame rail holes and fastens to existing weldnuts and bolts on the bumper beam.
Socket wrench, torque wrench, 6" socket extension, 3/4" socket, and 21mm socket.
Yes. Step 1 of the installation requires you to lower the spare tire for ease of installation. After installation is complete, you raise the spare tire back into position in Step 8.
Professional installation takes approximately 43 minutes. DIY installation for a novice takes approximately 60 minutes.
The hitch includes: four 1/2-13 UNC carriage bolts, 1-1/2" grade 8 (part 10-10287); four 1/2-13 UNC serrated flange nuts grade 8 (part 20-00062); two 0.250 x 1.50 x 3.00" square hole spacers (part CM-SP4); two 0.188 x 1.00 x 3.00" square hole spacers (part CM-SP40); and two 1/2" x 30" fishwire pieces (part 1_2 x 30 FISHWIRE).
In Step 2, remove the existing M14 bolts that connect the bumper beam to the frame rail on both the driver and passenger sides of the vehicle. Save these bolts because you will reinstall them in Step 6.
The fishwire technique is used to route the 1/2-13 carriage bolts and spacers through the frame rails and bumper beam. Step 3 uses the reverse pull fishwire technique to insert bolts through the large round holes in the frame rails. Step 4 uses the standard fishwire technique to insert bolts through the bumper beam ends and out the slot in front of the bumper beam. Detailed diagrams for both techniques are provided in the manual.
Torque all 1/2" hardware (the carriage bolts and hex flange nuts) to 110 lb-ft.
Torque the M14 bolts (the existing bumper beam bolts reinstalled in Step 6) to 126 lb-ft.
No. In Step 5, install the 1/2-13 hex flange nuts loosely onto the 1/2" carriage bolts. Do not tighten them until Step 7, after you have reinstalled the M14 bolts removed in Step 2. This allows proper alignment of all components before final tightening.
Follow these steps in order: (1) Lower spare tire; (2) Remove existing M14 bolts from bumper beam and save them; (3) Use reverse pull fishwire technique to insert carriage bolts and CM-SP40 spacers through frame rail holes; (4) Use fishwire technique to insert carriage bolts and CM-SP4 spacers through bumper beam; (5) Raise hitch into position and loosely install hex flange nuts; (6) Reinstall the M14 bolts removed in Step 2; (7) Torque all hardware to specification; (8) Raise spare tire back into position.
Yes. Step 2 requires you to remove the existing M14 bolts connecting the bumper beam to the frame rail on both sides. You must save these bolts and reinstall them in Step 6 as part of the hitch installation.
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 prevent loosening due to vibration and use.
Do not exceed your vehicle manufacturer's recommended towing capacity. Although this hitch has a gross load capacity of 6,000 lbs. trailer weight and 600 lbs. tongue weight as a weight-carrying hitch (or 10,000 lbs. and 1,000 lbs. as a weight-distribution hitch), your Dodge Ram 1500 may have a lower manufacturer-recommended limit that you must follow.

Yes. Lower the spare tire in Step 1 for ease of installation, then raise it back in Step 8 after installation is complete.
Yes, the Curt 56258 is designed for all Lincoln MKZ models, including hybrid versions. The installation procedure differs slightly for hybrid models: the vehicle battery is located in the trunk on the driver side, rather than under the hood. All other installation steps remain the same.
Yes. The Curt 56258 is compatible with all Lincoln MKZ models, including hybrid versions. The only difference is the battery location: hybrid models have the battery in the trunk on the driver side, while non-hybrid models have it under the hood on the driver side.
The Curt 56258 has two amperage ratings: Signal Circuits are rated at 3.0 amps per side, and Tail/Running Circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
You will need a panel trim removal tool. Depending on your vehicle's existing ground points, you may also need a drill to create a 3/32" pilot hole for the ground screw. All other fasteners and hardware, including the provided screw, double-sided tape, cable ties and 4-flat dust cover, are included with the harness.
Yes. You must disconnect the negative battery terminal before beginning installation. On non-hybrid Lincoln MKZ models, the battery is located on the driver side under the hood. On hybrid models, the battery is located on the driver side in the trunk. Reconnect the battery only after all installation steps are complete.
The yellow wire end of the custom wiring harness connects to the driver side taillight connectors, and the green wire end connects to the passenger side taillight connectors. Both are inserted between the separated vehicle taillight wiring harness connectors, located behind the trunk scuff panels. Ensure the connectors are fully inserted with locking tabs in place.
The white ground wire must be secured to a suitable grounding point near the taillight connector. You can use an existing screw with nut in the vehicle's frame, or drill a 3/32" pilot hole and use the provided screw. The area should be free of rust, dirt and paint. Secure the wire using the ring terminal and provided screw.
Mount the black converter box on a flat spot inside the vehicle near the taillight using the provided double-sided tape. The area should be clean and dry to ensure the tape adheres properly.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties to prevent tangling and damage.
Drilling may be required for the ground wire installation. You will need to locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle's frame. If no suitable existing point is available, you must drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All installation steps must be followed to ensure the wiring harness will function properly.
After installation is complete, reinstall all items removed during the install, including trunk floor coverings, storage trays, scuff panels and trunk liner. Reconnect the negative battery terminal. Install the provided 4-flat dust cover to prevent corrosion. Test the harness for proper function using a test light or by connecting a properly wired trailer.
The kit includes the custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal, a provided ground screw, double-sided tape for mounting the converter box, cable ties for securing loose wires, and a 4-flat dust cover to prevent corrosion.
