In the world of commercial towing, more is expected. A job cannot be completed if the equipment cannot handle the workload. That is why CURT developed the Commercial Duty class 5 trailer hitch. Constructed from steel and engineered for power, these class 5 hitches are designed to complement the towing power of full-size, commercial pickup trucks, including diesels and chassis cabs. They can easily handle a variety of oversize trailers, including toy and car haulers, livestock trailers, dumper trailers, large flatbed trailers, large boat trailers and more (NOTE: Never exceed the lowest weight capacity of any towing component). This particular class 5 hitch features a gross trailer weight capacity of 18,000 lbs. and a tongue weight capacity of 2,700 lbs. It is designed to be a custom trailer hitch for certain years of the Dodge Ram 1500, 2500 and 3500 (to verify your vehicle compatibility, see application info). All CURT Commercial Duty class 5 hitches feature a 2-1/2" x 2-1/2" receiver tube opening to accept the strongest of ball mounts and towing accessories. They are perfect for mounting standard ball mounts, pintle mounts, tow hooks and weight distribution hitches as well as winch mounts and cargo carriers. CURT class 5 tow hitches are protected by a co-curing of liquid A-coat and carbide black powder coat finish. They also mount with grade-8 hardware, included with each hitch.

Depending on the vehicle application, available options may include Class 3, Class 4 and heavy-duty receiver hitches with different gross trailer weight and tongue weight capacities.
A 2" x 2" receiver opening is one of the most common hitch sizes and works with a wide range of towing accessories, including ball mounts, bike racks, cargo carriers, hitch steps and tow hooks. When towing a trailer, you may also need a properly rated trailer ball, hitch pin, wiring harness, brake controller or weight distribution system.
CURT trailer hitches feature a durable black finish designed to help protect against rust, scratches and exposure to road conditions. Many models install using existing holes in the vehicle frame, although drilling, trimming or temporary removal of vehicle components may be required for certain applications.
Use our vehicle fitment tools to find the correct CURT 2" trailer hitch for your year, make and model. Always compare the hitch rating with your vehicle’s towing capacity and the ratings of every component in your towing setup. The maximum towing capacity is determined by the lowest-rated component.

Yes, the Curt 15704 is designed for 03-current Dodge Ram 2500/3500 models without an OEM receiver hitch. Confirm your vehicle does not have a factory-installed receiver hitch before purchasing. If your truck has a factory hitch, you may need to loosen and push it toward the rear to create space for the CURT hitch installation.
Yes, the Curt 15704 fits 03-08 Dodge Ram 1500 models built after November 2002, provided your vehicle does not have an OEM receiver hitch. Vehicles built before November 2002 are not compatible with this hitch.
Yes, the 15704 is designed for both short bed and long bed configurations. Installation differs by bed length: long bed vehicles use the front-most hole on the hitch side plates, while short bed vehicles use the middle hole. The correct spacers and hardware are included for both configurations.
The Curt 15704 has a gross load capacity of 18,000 lbs trailer weight and 2,700 lbs tongue weight when used as a weight carrying hitch.

You will need: a socket wrench, a torque wrench, an 8 inch socket extension, and 13/16" and 7/8" sockets. These tools are required to properly install and torque all fasteners to specification.
The kit includes: 2 HHCS 9/16-12 UNC Grade 8 bolts (part 10-10500), 2 pieces of 9/16" fishwire, 2 flat washers 9/16" (part 30-00202), 6 serrated flange nuts 9/16-12 UNC Grade 8 (part 20-00104), 4 carriage bolts 9/16-12 UNC 1-3/4" Grade 8 (part 10-10328), 2 spacers .313 x 2.13 x 2.13" with 9/16" square hole (CM-SP68), 2 spacers .313 x 1.50 x 3.00" with 9/16" square hole (CM-SP74), and 6 spacers .188 x 1.25 x 1.50" with round holes (CM-SP8).
No, drilling is not required. The hitch uses existing holes in the vehicle frame rails and bumper beam. All mounting points align with factory holes.
Professional installation takes approximately 60 minutes. DIY installation for a novice takes approximately 77 minutes.
Fishwire is a flexible wire used to route carriage bolts through tight spaces where a bolt cannot be inserted directly. In this installation, fishwire is used to thread 9/16" carriage bolts through access holes in the frame rails and through the spacers. The fishwire guides the bolt through the hole, then is removed once the bolt is in position. Refer to the FISHWIRE TECHNIQUE diagram on the manual for the specific routing.
The manual does not explicitly state whether bumper removal is required. However, installation steps reference fishwiring bolts through the bumper beam and accessing frame rails, which may require bumper loosening or removal. If your vehicle has a factory hitch, you may need to loosen the hitch and bumper beam and push it toward the rear to create space for the CURT hitch.
For long bed vehicles, use the front-most hole on the hitch side plates for both the front and rear mounting points. Short bed vehicles use the middle hole instead.
For short bed vehicles, use the middle hole on the hitch side plates for both the front and rear mounting points. Long bed vehicles use the front-most hole instead.
The CM-SP74 spacers (.313 x 1.50 x 3.00" with 9/16" square hole) are installed at the front mounting holes. Slide these spacers through the ends of the frame rails and align their holes with the front mounting holes on the hitch side plates.
The CM-SP68 spacers (.313 x 2.13 x 2.13" with 9/16" square hole) are installed at the rear mounting holes. Slide these spacers through the ends of the frame rails and align their holes with the rear mounting holes on the hitch side plates.
The CM-SP8 spacers (.188 x 1.25 x 1.50" with round holes) are installed between the tow loops and hitch side plates. Use enough spacers to prevent the tow loops from pulling into the hitch when the hex bolts are tightened. These spacers maintain proper clearance and alignment.
For 1500 models, use the bottom slot on the hitch side plate when aligning with the vehicle tow loops. 2500/3500 models use the top slot instead.
For 2500/3500 models, use the top slot on the hitch side plate when aligning with the vehicle tow loops. 1500 models use the bottom slot instead.
All 9/16" fasteners on the Curt 15704 are torqued to 150 lb-ft. This includes the carriage bolts installed in steps 4-5 and the hex bolts installed in steps 8-10. Use a torque wrench to ensure proper tightness.
Do not exceed your vehicle manufacturer's recommended towing capacity. While the Curt 15704 is rated for 18,000 lbs trailer weight and 2,700 lbs tongue weight, your vehicle's manufacturer may specify a lower limit. Always follow the more conservative specification.
After installation, verify that all fasteners are tight and all structural components are sound. Periodically check the hitch during use to ensure fasteners remain tight and the hitch shows no signs of damage or wear.
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.
