Commercial Duty Class 5 Trailer Hitch with 2-1/2" Receiver #15860


Towing the skid steer out to the construction site? Hauling some materials to that next big job? Moving some livestock around the farm? Whatever work you need to get done, give yourself the professional advantage with a CURT Commercial Duty class 5 hitch.

Commercial Duty class 5 hitches are designed, manufactured, finished and tested to excel in heavy-duty towing applications, particularly commercial jobs. They are constructed from high-quality steel welded into a powerful frame. The center section is comprised of an extra-large steel body, giving the tow hitch maximum strength for tough jobs. The hitch also mounts into place using grade-8 hardware for solid integration and reliability.

All class 5 trailer hitches are made for vehicle-specific application. The advantages of this approach include a custom fit without any tedious modifications to the vehicle, as well as optimum towing strength to complement your truck. This specific custom class 5 hitch is engineered to fit certain years of the Chevy Silverado 2500 HD or 3500 HD and GMC Sierra 2500 HD or 3500 HD (see application information to verify compatibility with the year, make, model and style of your truck).

This Chevy / GMC hitch is tested for extreme towing, rated for a weight carrying capacity of 20,000 pounds gross trailer weight and 2,700 pounds tongue weight. It also has a weight distribution hitch rating of 20,000 pounds WD and 2,700 pounds WDTW. This makes it ideal for towing all manner of large utility trailers, flatbed equipment haulers, livestock trailers, full-size travel trailers and much more (never exceed the lowest-rated towing component). This class 5 hitch is also equipped with large safety chain loops, providing a solid mounting point for heavy-duty hooks and safety chains for added security on the road.

To complement the superior towing capacity of this hitch and your truck, all Commercial Duty class 5 hitches come with an industry-standard 2-1/2" x 2-1/2" receiver tube opening. The hitch receiver is strengthened with a steel collar welded into place, and it readily accepts the largest of towing accessories -- anything with a standard 2-1/2" shank. It is ideal for heavy-duty ball mounts, pintle hitches, weight distribution hitches and more. We also offer reducer sleeves to adapt the 2-1/2" receiver to fit 2" shanks, as well as hitch tube covers to protect the hitch receiver when not in use.

Like all CURT custom receiver hitches, Commercial Duty class 5 hitches are engineered, manufactured, finished and tested in the USA (may include imported hardware). This gives us direct control over the quality of each hitch from start to finish. We design our hitches using cutting-edge technology and real vehicles in our engineering bays, resulting in hitch designs that are perfectly suited for each vehicle application. We also fabricate and weld our trailer hitches using a combination of manual and robotic processes, ensuring the utmost speed and accuracy.

CURT trailer hitches are finished with industry-leading rust, chip and UV protection. We accomplish this with a two-part finishing process. First, the hitch is immersed in a liquid Bonderite® bath that completely covers the inside and outside of the hitch in a rust-resistant layer. Second, a carbide black powder coat is applied over the top of the Bonderite®, giving the hitch highly durable protection against scuffs, scratches and rust. The two layers of finish are also cured together to form a superior shield to outlast the rigors of the elements and the jobsite, season after season.

To fully back the towing strength of our class 5 hitches, we put each design through stringent, real-time testing. We maintain a dedicated engineering and testing facility near Detroit, MI where all of our hitches are tested according to SAE J684. They are placed on actual vehicles and exposed to multifaceted testing to simulate real towing conditions. This testing gives us complete confidence in our hitches and provides you with a safe, dependable piece of equipment you can be proud to mount on your truck.

Like all CURT custom hitches, this Commercial Duty class 5 hitch is backed by a limited lifetime warranty.
