Tackling a substantial load on the way to your next major project? Pulling your yacht for a weekend on the water? Transporting livestock from the county auction to your farm? No matter the towing challenge, make it seem effortless with CURT.

CURT Xtra Duty class 5 trailer hitches excel in design, capacity, and durability to offer you a trustworthy extension of your truck. These robust hitches are meticulously engineered to endure the demands of towing the largest non-commercial trailers, matching the strength and reliability of full-size pickup trucks, vans, and SUVs.

Every class 5 hitch is custom-designed to achieve a vehicle-specific fit, guaranteeing seamless integration and maximum towing capability. This specific custom class 5 hitch is crafted to be installed on certain models of the Ram 2500 or 3500 and Dodge Ram 1500, 2500, or 3500 (please verify its compatibility with your exact year, make, model, and style using the application information). The vehicle-specific design ensures a hassle-free installation, minimizing or even eliminating the need for drilling and modifications. Additionally, this hitch includes high-strength grade-8 hardware for a secure attachment.

This class 5 hitch for Dodge Ram models boasts an oversized main body crafted from high-strength steel. Its extra-large center section is purpose-built to provide the necessary towing capacity for demanding tasks. Specifically, this hitch has been rigorously tested and rated for a gross trailer weight of 17,000 pounds and a tongue weight of 2,550 pounds. It is also compatible with a weight distribution hitch, with a rating of 17,000 lbs. WD and 2,550 lbs. WDTW. This versatility makes it the perfect solution for a wide range of heavy-duty trailers, from full-size utility trailers and equipment haulers to horse trailers and yacht trailers. It's crucial, however, to never exceed the capacity of the lowest-rated towing component.

All CURT Xtra Duty class 5 hitches feature an industry-standard 2" x 2" receiver tube opening, offering versatile compatibility with a wide range of heavy-duty ball mounts, pintle hitches, weight distribution hitches, and other towing accessories. Additionally, it can readily accommodate cargo carriers or bike racks to expand your storage capacity. The 2" hitch receiver is fortified with a steel collar for extra durability, and its open-back design makes it easy to clear away dirt and debris. When not in use, you can install a hitch tube cover to safeguard it from dirt and corrosion.

For your peace of mind on the road and the safety of you and your passengers, every CURT custom tow hitch design undergoes comprehensive testing in accordance with SAE J684 standards. Our testing is conducted at our in-house facility in Detroit, MI, using actual vehicles and rigorous testing procedures that replicate real towing scenarios. All of our class 5 hitches are equipped with spacious safety chain loops designed to accommodate heavy-duty hooks and safety chains.

Just like all other CURT custom tow hitches, our Xtra Duty class 5 hitches are proudly manufactured in the USA (though some hardware may be imported). Each one is meticulously engineered using real vehicles to guarantee a tailor-made fit for every application. The fabrication and welding of each trailer hitch involve a blend of robotic and manual processes, ensuring both precision and efficiency.

Last but not least, our custom trailer hitches undergo an industry-leading finishing process that delivers unmatched protection against rust, chipping, and UV damage. It all starts with the hitches being meticulously descaled, ensuring a smooth surface. Following this, they are submerged in a liquid A-coat, providing the tow hitch with an initial rust-resistant layer both inside and out. Subsequently, a robust carbide black powder coat finish is expertly applied over the A-coat. Finally, these two finishes are cured together, creating a robust barrier that defends against scuffs, scratches, and the harshest elements.

CURT custom-fit trailer hitches are engineered for enduring reliability and come with a limited lifetime warranty for your peace of mind.
