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 2500 or 3500 and Dodge Ram 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.
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 Dodge Ram 1500, 2500 and 3500 (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 hitch weight is 51 lbs.
Yes, the Curt 13361 (also designated RRH13361) is designed for 2002-current Dodge Ram pick-ups in 1500, 2500, and 3500 models, in both short bed and long bed configurations.
Yes. The hitch uses different mounting holes depending on bed length. Short bed models use one hole on each side, and long bed models use a different hole on each side. The installation diagram clearly marks which holes to use for each configuration.
Yes. The installation diagram shows that 1500 models use one hole, while 2500 and 3500 models use a different hole. Align the hitch holes to the correct frame holes for your specific model before installation.
The kit includes: 4× 1/2-13 UNC 2" grade 8 bolts (10-10288); 2× 1/2-13 UNC 2-1/4" hex head cap screws (10-10530); 6× 1/2-13 UNC grade 8 serrated flange nuts (20-00062); 2× 1/2" flat washers (30-00133); 2× 0.250" × 1.50" × 3.00" square hole spacers (CM-SP4); 2× 0.250" × 2.13" × 2.13" square hole spacers (CM-SP48); 4× 0.188" × 1.50" × 3.00" round hole spacers (CM-SP34); 2× 0.188" × 1.50" × 2.00" round hole spacers (CM-SP32); and 1× 1/2" fishwire (1_2 FISHWIRE).
No. The installation diagram explicitly states 'NO DRILLING REQUIRED'. The hitch aligns to existing holes in the Dodge Ram frame.
Yes, fishwiring is required. Fishwiring is the process of using a wire (the 1/2" fishwire is included) to guide and slide fasteners into position through access slots in the frame. Specifically, you will fishwire the forward-most carriage bolts into position through the frame access slots.
The manual does not specify whether bumper removal is necessary. However, the installation diagram shows that the rearward-most carriage bolts pass through the bumper beam, suggesting the bumper may need to be removed or repositioned for access. Consult the vehicle service manual or a professional installer for clarification.
1. Raise the hitch into position and align all holes in the hitch to holes in the frame (using the correct holes for your bed length and model). 2. Insert hex bolts through side plates into tow loops, using spacers as needed between hitch and tow loop. Install the outer spacer and flange nut on both sides. 3. Use the included fishwire to slide square hole spacers into place and fishwire the forward-most carriage bolts into position through frame access slots. Insert the rearward-most carriage bolts through the bumper beam and into position on each side. 4. Install remaining hex flange nuts and torque all 1/2" fasteners to 110 lb-ft.
Spacers are used as needed between the hitch and tow loop to ensure proper alignment. The installation diagram shows that square hole spacers are slid into place using the fishwire through the frame rails. Round hole spacers are used at various points as required for proper fit. The exact number and placement of spacers depends on your specific vehicle configuration.
All 1/2" fasteners must be torqued to 110 lb-ft. This applies to the hex bolts, hex head cap screws, and flange nuts used in the installation.
The manual specifies a gross load capacity of 6,000 lbs. trailer weight and 600 lbs. tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The manual specifies a gross load capacity of 10,000 lbs. trailer weight and 1,000 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.
Do not exceed your vehicle manufacturer's recommended towing capacity. Even though the hitch has rated capacities (6,000 lbs. trailer weight as a weight-carrying hitch, or 10,000 lbs. as a weight-distribution hitch), your Dodge Ram may have a lower maximum towing capacity that must be respected.
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, but regular inspection before towing is recommended.

Yes, Curt part number 55504 is designed for Dodge Ram 1500, Dodge Ram 2500, and Dodge Ram 3500 models. The installation uses the vehicle's existing taillight wiring harness in positions T3 and T5.
The Curt 55504 is a T-connector trailer wiring harness that taps into your vehicle's existing taillight wiring. It includes a converter box, a 4-flat connector for the trailer, and wiring with yellow and green leads for the driver and passenger sides respectively.
The kit includes a T-connector with yellow and green wires, a black converter box, a white ground wire with eyelet and screw, double-sided tape, cable ties, and a 4-flat connector. You will need a drill with a 3/32" bit if no suitable existing screw is available for grounding.
The manual does not specify whether the battery must be disconnected. Contact Curt Manufacturing or your installer for this safety requirement before beginning work.
Locate the vehicle's taillight wiring harness in positions T3 and T5 under the vehicle. The harness will have connectors similar to those on the T-connector included in the kit.
On the driver's side, separate the vehicle's taillight connectors without damaging the locking tabs. Insert the T-connector end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place. Repeat on the passenger's side using the green wire T-connector end.
Route the T-connector end with the green wire under the vehicle to the passenger's side taillight wiring harness. Avoid any location that may pinch or cut the wire during routing.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no existing screw is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage or personal injury.
Drilling is required only if no suitable existing screw with nut is available on the vehicle's frame for grounding the white wire. If drilling is necessary, use a 3/32" drill bit. Always verify that no miscellaneous items are hidden behind or under any surface before drilling to avoid damage and personal injury.
Drill a 3/32" hole if no existing screw is available on the vehicle's frame for grounding the white wire.
Adhere the black converter box to the frame of the vehicle using the double-sided tape provided in the kit.
Secure any loose parts of the T-connector with the cable ties provided in the kit.
Route the 4-flat connector to the center of the vehicle and secure it in a convenient out-of-the-way location.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface. Drilling without checking can cause damage to hidden components and personal injury.
Avoid any location that may pinch or cut the wire when routing the T-connector under the vehicle. Also, do not damage the locking tabs on the vehicle's connectors when separating them.
